There are many differences between plant and animal cells. Animal cells have a rounder shape while plant cells have a more rectangular shape. Plant cells have chloroplast and animal cells do not. Plant cells have a cell wall, animal cells do not. Describe the movement of euglena, ameoba and parmecium?

The paramecium moves by beating its cilia, therefore propelling it through the water. The amoeba moves by creating pseudopods with a finite amount of cytoplasm. The euglena moves by its long flagellum. My question is:
What are the best and worst colors for photosynthesis and why?
 

Sorry...
Here's my link.
 

Out of ROYGBIV, the best colors for photosynthesis are blue and red. The worst color for photosynthesis is green. This is because the green color is not being absorbed by the chlorophyll, while red and blue are easily absorbed by the chlorophyll.

A heterotroph is an organism that cannot make food on its own, so it therefore eats other organisms - plants, animals, etc. An autotroph is an organism that makes its own food through the process of photosynthesis. Generally, heterotrophs are animals, and autotrophs are plants. My question is: what are the three groups that compose the structure of an amino acid ?


here'a a lifeline ;)
 

Amino acids are the building blocks of proteins and join together through the formation of peptide bonds. Amino acids are made up of three structures an amino group(NH2), a variable group, and a carboxyl group(COOH)(from left to right). The variable group differs based on the type of amino acid.

Describe the function(s) of enzymes and their characteristics.

I'm here if you need help.
 

The function of enzymes is to speed up the process in a chemical reaction. It does this without changing itself so it is a catalyst, as well as a protein. An enzyme has an active site to which the substrate will attach itself to when they bump into each other, in the right way, by chance. An enzyme is lock and key specific, it can only be used for a certain substrate, not a wide variety.

What is the term that refers to "plant sweat", and how & why do plants do this?

yup.
 

Ray are u obsessed with Enzymes??? lol
 

Plant-sweat is called transpiration.plants transpire because it needs to take up water. It also keeps the plant cool, hence called "sweat". They lose this water through stomata or pores on the leaves which are microscopic.

Give three differences between Active and Passive transport and define the terms.
heres a bit of help
 

active transport requires energy while passive transport don't. passive tranport always operates from regions of greater concentration to regions of lesser concentration while active transport can go against the concentration. no external sourse of energy is required for passive transport and active transport uses ATP.

What are the elements important to life using C HOPKINS CaFe Mg NaCl?

Need Help?
 

we should all be ocd about our enzymes!!!! they are what keeps us alive!
:)
 

The phrase C. Hopkins' CaFe NaCl is an acronym for the vital elements for humans. The C stands for the important element Carbon, which is what humans are composed of. The rest of the acronym is as follows: Hydrogen, Oxygen, Phosphorus,Potassium, Iodine, Nitrogen, Sulfur, Calcium, Iron, Sodium, and Chlorine. All of these elements are either solids, liquids, or gases. Slow cycling elements are Calcium, Phosphorus, Potassium, Carbon, Iodine, and Iron. These elements are scarcely available. The fast cycling elements are Oxygen, Sodium, Sulfur, and Nitrogen. These elements are abundant within nature. All of these elements are needed for life and if one is removed then you probably won't live.

Question: What are the functions of the stomate and guard cells within a leaf?
Is This Too Hard?
 

The stomate and guard cells allow transport of materials in and out of a leaf. They block out things that are not wanted in the leaf and allow others in that could help the leaf in any way. The guard cells are the cells on either side of the stomate (open area). They do the actual process of choosing items to go into the cell. The stomate is just the open area between them that the objects going in and out of the leaf pass through.

Question: What are the functions of the xylem and phloem in a leaf?

Help for xylem


Help for phloem
 

arteries veins and capillaries all carry blood. However, arteries are the largest and thickest of the three, are very elastic, have no valves and carry blood away from the heart. Veins are partially elastic, have valves and carry blood to the heart. Capillaries are the smallest of the three, are one cell thick, and connect the arteries with the veins. The capillaries also exchange O2+CO2.

My question is: Name and describe the types of blood circulation in the human body.

Need Help?
 

Sorry i didn't see the other question before.
Systemic circulation goes around the body, feeding your body and head cells.
Pulmonary circulation, blood goes to the lungs to get oxygen.
Renal circulation brings blood to the kidney to be filtered.
Coronary circulation feeds the heart tissue.
Hepatic-Portal circulation, drain the digestive organs, spleen, and pancreas and deliver the blood to the liver via hepatic portal vein.

Describe the path blood takes through the heart.

Click Here
 

On the right side of the heart blood enters the through the inferior vena cava and superior vena cava. It empties oxygen-poor blood from the body into the right atrium. On the left side of the body the pulmonary vein empties oxygen-rich blood from the lungs into the left atrium.
My Question is:
Describe the functions of the Nucleus, Mitochndria and Lysosome in a cell?
Need Some Help?-Nucleus
Need Some Help?-Mitochondria
Need Some Help?-Lysosome
 

Sorry......
Here are my links:
Nucleus
Mitochondria
Lysosome
 

study study study !!!
:)
 

The nucleus in the cell contains most of the cell's genetic material, organized as multiple long linear DNA molecules to form chromosomes and is known as the "control center" of the cell. The mitochondrion is the powerhouse of the cell because it generates ATP. Lysosomes digest excess or worn-out organelles by secreting enzymes.

My question is: Describe dehydration synthesis and hydrolysis and how they relate to organic componds.

Dehydration and Hydrolysis
 

During dehydration synthesis, you are building something up while taking water out.
Hydrolysis is simple; it is the reverse of dehydration synthesis.
This is connected to organic compounds because these processes involve carbon and in order for something to be an organic compound, there has to be at least one carbon.

Systemic circulation is The movement of blood to your head and throughout your body. Pulmonary circulation is the movement of blood to and from your lungs to pick up Oxygen. Coronary circ. is the movement of blood through the muscles of your heart.

What is the difference between Eukaryotic and Prokaryotic cells

Click Here
 

Systemic circulation carries blood between the heart and the rest of the body. The blood begins in the left ventricle and is retured to the right atrium.
Pulmonary circulation carries blood to and from the lungs. During this process oxygen is added and carbon dioxide is removed from the blood.
Coronary circulation is the branch of the systemic circulation that supplies blood to the muscle of the heart.

What is the roll of the lymphatic system?
Need help?
 

Oops! i answered the same question as g2 cause it wasnt there before. What do i do mr.j?
 

There are many rolls of the lymphatic system. One of the rolls is to collect and return fluids inside the body, including plasma protein to the blood,
to help maintain fluid balance. Another roll is to defend the body against disease by producing lymphocytes(aka white blood cells). The last main roll is to absorb lipids from the intestine and transport them to the blood.

Describe the process of a blood clot.

Click Here for help and to see a visual!
 

A blood clot can only happen if all the steps are included. There has to also be platelets, prothrombin, and fibrinogen to start a clot in the blood. First you have to get some sort of wound where the platelets are damaged. This causes the production of thromboplastin, which allows the prothrombin, with the thromboplastin to form thrombin. This requires the use of calcium. The thrombin has a reaction with the fibrinogen and makes fibrin. Fibrin looks a lot like a spider web. This web of fibrin catches anything that might be in your blood and causes a clot.

What are the names of three types types of white blood cells and what do they do?
For a hint... Click here!
 

Three types of white blood cells are memory cells, regulatory T-cells, and cytotoxic T-cells, The job of the memory cells is to remember what kind of antibody was used to kill a specific pathogen so when that pathogen enters the body again the memory cells can detect it and know what kind of anitbodies to make. The job of the regulatory T-cell is to regulate the immune system. They shut down T-cells towards the end of its life cycle and eliminate T-cells that escaped negative selection in the thymus. The job of the cytotoxic T-cells is to destroy virally infected cells and tumor cells.






Ok so my question is....
What kind of circulatory system does a grasshopper have? Human?



Here's my hint:)
 

good job folks :)
hj
 

Grasshoppers have open circulatory systems. Humans have closed circulatory systems.

So here is my question...
What are three major differences between organic and inorganic matter?

Having Trouble??
 

...and what are the definitions of both open and closed circulatory systems??? compare and contrast.
:D
 

Im not realy sure which question to answer Hj's or Alexis's so ill answer both Three differences between inorganic and organic compounds ar that organics contain hydrocarbon while inorganics do not. Inorganic compounds are also aple to comprise of metal while organics cannot and organic compounds are created by living things inorganic compounds are formed by the forces of nature or human intervention in nature.
The differences between a closed an open circulatory system is that in a closed system the blood is confined within blood vessels and in an open circulatore system they souround the tissues and organs.

My question is from way back. What is the name of the system used to name and classifie differant animals?
 

To answer conners question, the binominal nomenclature. This process of taxonomy was invented by Carolus Linneaus a Swede. The first name, both in latin would be its genus and then second its the species. The orgamisms would be grouped in animals with simmilar life habbits and then the groups wouold get more detailed and more detailed.

What is the difference between absorbtion and digestion and where do they occur?
 

The difference between absorption and digestion is digestion is the chemical and physical breakdown of food into compunds usable by the body, and absorption is the taking up of the compounds by the body, either through the stomach lining or through the intestinal walls. My question is what is the difference between the structure of a plant cell and the structure of an animal cell?
 

rickys Q is a repeat... so
my question....
explain what happens during both the light and dark reactions of photosynthesis. Be Specific :)
 

In a light reaction, light energy from the sun is used to split water (called photolysis) which has been sucked in by plants by transpiration. The sunlight hits chloroplasts in the plant and the leafs of the plant, causing an enzyme to break apart the water. Water, when broken, makes oxygen, hydrogen, and electrons. The hydrogen converts to NADP which is then used in the light reactions. Oxygen diffuses out of the plant as a waste product of photosynthesis and ATP is synthesized from ADP and inorganic phosphate. This all happens in the granna of chloroplasts. In the dark reaction, sugars are built up using carbon dioxide and the products of the light reactions (ATP and NADP) and various other chemicals found in the plant in the Calvin Cycle. Therefore, the dark reaction cannot happen without the light reaction. Carbon dioxide diffuses into the plant and along with chemicals in the stroma of the chloroplast and ATP and NADP, glucose is made and finally, transported around the plant by translocation.

My question: A group of cells that work together to perform a function is called a what?
Confuddled?
 

Xcellent job ZeeBee :)
 

Its tissues :) a collection of similar cells that group together to perform a specialized function. There are 4 primary tissue types in the human body: epithelial tissue, connective tissue, muscle tissue and nerve tissue.

QUESTION
What are Active and passive immunities and how do they differ???give examples for each too :)

need help???
 

>( heyyyy IM NOT JEROMEEEEEE IM AGGLE AGGLE AGGLE ANGLE
 

i'd recognize ya either way angle jay aggle
:)
 

wait, my question is a repeat?, so I should answer that one and ask another question?
 

And I will answer the question anyways. So what happens during the dark reactions of photosnthesis is carbon dioxide is converted to sugar using ATP and NADPH. Then carbon dioxide is combined with carbon sugar and carbon sugar breaks down into two molecules, glucose and fructose. Glucose and fructose can be used to make sucrose. All of this happens in the cholorplast. That is what happens during the dark reactions of photosynthesis. During the light reactions of photosynthesis, which is the first stage of photosynthesis, light energy is being converted to chemical energy. It is being transferred by the energy carriers ATP and NADPH. This light reaction is also happening in the chloroplast. My question is What are the stages of meiosis?


There Mr. Johnson, I hope that is specific enough for you. : ), and for my science fair project, is it okay to do my project on the effect of gatorade verses water on the pulses recovery time?
 

Oh, sorry Mr. Johnson, I answered the same thing as Zahraah because I thought it was for me. haha. So I will answer the next one or is mine okayyy??
 

The two cell divisions in Meiosis are called Meiosis 1 and Meiosis 2. Each of these stages are broken into the same stages as mitosis; Prophase, Metaphase, Anaphase, Telophase. Meiosis 1 begins with Prophase 1, the Metaphase 1, Anaphase 1 and Telophase 1. Then Meiosis 2 begins with Prophase 2, Metaphase 2, Anaphase 2, and Telophase 2. Basically Meiosis is a two-part cell division process in organisms that sexually reproduce, which results in gametes with one-half the number of chromosomes of the parent cell.
My question is What is Coronary Circulation and what does it do? Hint
 

Coronary circulation is the circulation of blood throughout the inner chambers of the heart. The blood is first pumped through the left side of the heart through the aorta and comes back into the heart via either the superior or inferior vena cava on the right side of the heart to feed the cells of the heart.
My question is: How are ATP and ADP related to cell respiration?

HELP!! I'm STUMPED!!
 

Ugh this is more work than i thought it'd be
 

hey johnson(:,
so the midterm is based on all these questions even for the regent classes?
 

ATP and ADP are energy molecules (adenosine triphosphate and adenosine diphosphate, respectively). In ATP there are 3 phosphate groups, hence triphosphate. When you break off one of those phosphates you release energy, and it becomes adenosine diphosphate. Adding one will store energy in it. Therefore ATP and ADP provide energy to help start processes in cell respiration by providing energy. Same with photosynthesis. ATP releases a phosphate group in order to help carry out some of the parts of photosynthesis.


My question is what is sickle celled anemia?
Sickle cell
 

Sickle celled anemia is when the red blood cells are abnormal. The red blood cells are normally like life savers with the hole still in the center. Sickle celled anemia is when the cells are in different shapes the cause them to have less surface area and have an abnormal "squished" shape.
