Cell biologists have introduced radioactively labeled carbohydrates, fats, and amino acids to living cells, allowed time for cel

l metabolism, and then placed the cells in a blender and separated out the various cell organelles from the cytoplasm. They found the radioactive molecules could soon be detected as part of various cellular compounds, although the visible cell structures appeared unchanged. Which of the following is the best conclusion based on this information?
a) these "food" molecules are used only for energy.
b) most cell components are constantly being broken down and rebuilt.
c) radioactivity was transferred from the introduced molecules to the resident table molecules.
d) molecules diffuse at random through the cytoplasm and into cell organelles.

Answer:

b)

Explanation:

Based on the scenario being described within the question it can be said that the best conclusion is that most cell components are constantly being broken down and rebuilt. This can be concluded as the statement describes that the cells metabolize meaning they "build up" which are then placed in a blender which breaks them down again.

Which of the following model organisms is a multicellular worm usedto study the process of development? a)Saccharomyces cerevisi
san4es73 [151]

Answer:b) Caenorhabditis

Explanation:

The C.elgans is a species of Caenorhabditis. It is a namatode which can be male or hermaphrodite. It lays 1000 of eggs which can be used for the purpose of research studies. These worms share common genes and molecular pathways like in humans.

Many of the genes present in C. elegans have functional counterparts as that of humans which makes them useful for determining the cause of human diseases. The mutant forms of genes of C.elegans can be used for screening the thousands of drugs. The genes have been used to determine the effects of ageing in humans, cancer, diabetes and other diseases.

Due to above reasons the C.elegans are considered as model organisms.
