Write a letter to a friend who is thinking of going on a questionable “fad” diet. Convince them that this is a very bad idea.
define all the cell organelles with their discovery.
two cities are located at the same latitude but in different regions of earth. which of the following factors could cause these cities to have different climates?
a) Based on the class consensus model of natural selection what will happen to the
snail popluation over 20 generations on the island, assuming the conditions on the
island do not change?
To demonstrate your answer create a representation that shows what happens to the
banded and unbanded snails in the current population, at the first generation, at the
10th generation and the 20th generatio
The Ras protein functions as a molecular switch that is set to its “on” state by other proteins that cause it to release its bound GDP and bind GTP. A GTPase-activating protein helps reset the switch to the “off” state by inducing Ras to hydrolyze its bound GTP to GDP much more rapidly than it would without this encouragement. Thus, Ras Works like a light switch that one person turns on and another turns off. You are studying a mutant cell that lacks the GTPase-activating protein. What abnormalities would you expect to find in the way in which Ras activity responds to extracellular signals?
Testosterone in humans shapes the formation of the external genitalia and influences brain development in the fetus; at puberty, the hormone triggers the development of male secondary sexual characteristics.
Assume that you are a genetic counsellor and you have a case who is genetically male but developed as a female. What could be the defect in this case? How would you explain the situation to the case?
Please explain the refulation of dynamic structure of microtubules?
The gene for the human protein albumin spans a
chromosomal region 25,000 nucleotide pairs (25 kilo-
bases, or kb) long from the beginning of the protein-coding sequence to the end of the protein-
coding sequence, but the messenger RNA for this protein is only 2.1 kb long. What do you think accounts
for this huge difference?
