Thank you.

One of the ingredients present in the venom of Indian spectacled cobra, Naja naja is phospholipase A2(PLA2). We have discussed the site of action of PLA2 in a glycerophospholipid. PLA2 from cobra venom thus degrades the glycerophospholipids present in the cell membrane leading to cell lysis releasing its cytoplasmic contents.
a. Explain taking an example of any glycerophospholipid present in the cell membranes, how action of PLA2 brings out lysis

the student is now given sugar solutions with concentrations of 1%,5%,10% and 20%.

Explain how the student could use these solutions to estimate the concentration of sugar in the four fruit juices

Write down the first three steps of the scientific method. Think of a broad topic that you are interested in and which would make a good sociological study—for example, ethnic diversity in a college, homecoming rituals, athletic scholarships, or teen driving. Now, take that topic through the first steps of the process. For each step, write a few sentences or a paragraph: 1) Ask a question about the topic. 2) Do some research and write down the titles of some articles or books you’d want to read about the topic. 3) Formulate a hypothesis.

Create a brief research design about this topic in the form of a letter to a philanthropic or grant organization requesting funding for your study. How can you describe the project in a convincing yet realistic and objective way? Explain how the results of your study will be a relevant contribution to the body of sociological work already in existence.

What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an ocular lens power of 5x?

5x

15x

500x

50x

4. An advantage of electron microscopes compared to light microscopes is that electron microscopes

are inexpensive and commonly used in most biology laboratories

allow you to view living cells, while light microscopes do not

have higher resolution that allows you to view smaller specimens

allow you to view the true colors of the specimens being viewed

.To study the details of protein molecules on the surface of a cell, a biologist would likely use a

scanning electron microscope

transmission electron microscope

compound light microscope

dissecting microscope

1. Compare and contrast the structure and function of a compound light microscope and a dissecting microscope.

Both are electron microscopes, but the dissecting microscope has a higher magnification than the compound light microscope.

Both are electron microscopes, but the compound light microscope can view only nonliving things.

Both are light microscopes, but the compound light microscope has a higher magnification than the dissecting microscope.

Both are light microscopes, but the dissecting microscope can view only nonliving things
