Cell Signaling For AP Biology Assignment

Preparing specimen for electron microscope hard, light microscope still very useful as a window on living cells.

3. Explain your prediction for the effect Na+ Cl- might have on glucose transport. In other words, explain why you picked the choice that you did. How well did the results compare with your prediction?

Dissecting helps students appreciate the complexity of organisms, by actually being able to come in contact and see up close instead of learning about it through a textbook. Students will become more involved if they are able to do something, rather than just listen as they will mostly not retain anything. Therefore, speaking from experience the dissection is geared more for hands- on learners, but, it enables all students to practice their observational and following instruction skills. Comparing notes with other students this dissection enabled everyone to come up with a better visualization of how all the organs are interconnected in the human body. Looking through the textbook at pictures does not give an

Surface Tension: The measure of how difficult it is to stretch or break the surface of a liquid.

Red and white blood cells are the two types of blood cells in the human body. Red blood cells transport oxygen around the body which is transferred through the bloodstream. It moves oxygen into the body and then removes it. They are absorbed through its haemoglobin.

Write a brief description of the three slides (Neuron, Spinal Cord Smear and C.S of Myelinated Nerve Fibers) as though you were explaining it to someone who cannot see the slide.

Continued on in the semester Ms. Gussow has her students do extended drawings. In these drawings, they center in on certain parts of the human body. By now, they have shortened their time on them. "This is the best way

You would expect for the normal lung cells to not have to divide as often because those cells are not exposed to many things through out the day. The normal stomach cells on the other hand would be expected to divide more because there is a lot of acidity in the stomach and therefore those cells are exposed to a lot of things on a daily basis. As for the ovaries you would expect that there would be a little more cell division because that is where new life is formed and all of the things that come along with that which means that there should be more division going on.

5. A. Fimbriae- hair like Gram-negative bacteria that allows attachment and through that the bacteria is able to colonize.

1) Leaves- Main organ for photosynthesis and transpiration. A flattened, typically green and blade-like structure of a higher plant.

7. Support Productive struggle in learning mathematics. The teacher did this when the students were working on their own methods of solving the problem. He allowed time for the students to draw out their representations. It never said, in the reading, how much time was given for the students to draw arrays, but based off molly’s representation she had enough time to draw 160 individual boxes. Also, in the reading the teacher goes by and sees that some students have changed their method of solving the problem (Ex. Lines 38 provides evidence of Support Productive struggle in learning mathematics). That would not have happened if there was not enough time to have a productive struggle.

PM331 Essay: Exosomes, their cell biology, normal function in the cell, and role in disease.

A Cell is the smallest structural and functional unit of an organism and consists of cytoplasm and a nucleus enclosed in a membrane

In cells, the process of producing and releasing a particular chemical, whether a protein or some other regulatory molecule, often requires the presence of an external signal. Cells must therefore have specialized receptors for this signal, or ligand. There are several classes of cell surface receptors, including receptors with noncatalytic activity, such as G protein-coupled receptors, and those with catalytic activity such as receptor tyrosine kinases.

1. Introduction Babesias are tick-transmitted hemoprotozoan parasites belonging to the phylum Apicomplexa. These parasites are etiological agents of babesiosis that infect a wide spectrum of mammals thereby causing major health and economic problems in the livestock industry throughout the world. Babesia bigemina is one of several Babesia species known to cause bovine babesiosis. The disease is clinically manifested by anemia, fever, hemoglobinuria, and the presence of parasites in the host erythrocytes (Homer et al., 2000).
