I think the answer is letter A. I hope this helps and i would have someone check this to make sure it's the correct answer for sure.
Answer:
Reverse mutations in the colonies enabled to recover the ability to synthesize histidine. The 2-aminoanthracene is a chemical agent that induce mutations and therefore it is potentially a carcinogen.
Explanation:
A reverse (suppressing) mutation is a type of mutation capable of restoring the activity of previously mutated genes. On the other hand, 2-aminoanthracene is an aromatic amine carcinogen capable of inducing hepatic and skin tumors. In this case, 2-aminoanthracene has been used to induce reverse mutations at <em>loci</em> responsible for the synthesis of histidine.
Answer:
Answer is given below;
Explanation:
Lipids:
lipids are naturally occuring solvents that is insoluble in polar solvents(i.e water). They are composed of fatty acids and glycerols.Fatty Acids of lipids maybe
- Saturated Fatty acids
- Un-saturated Fatty acids.
Saturated Fatty Acids: They have carbon atom binded to hydrogen atom.
Un-saturated Fatty acids: They have some of their carbon atoms doubly attached in place of Hydrogen atom.
Answer:
it is B
Explanation:
it is Anti-A Individuals with type AB blood have both A and B antigens,
The group of animals that group or live together are called
analogies. Analogies are structures that
result from convergent evolution - species from different evolutionary branches
= no shared ancestry similar appearance examples - wings of bees and bats,
Australian mole an North American mole - both look similar, they occupy the
same niche.
