Which of the following statements about natural selection is true? A. Natural selection favors individuals that reproduce more than others. B. Natural selection occurs in opposition to evolution. C. Natural selection can be used by farmers to generate organisms with desirable traits.
Answer:
A DNA sequence codes for the same proteins in different species
Explanation:
All living organisms store their genetic information in DNA (genetic material). The manner through which information in the genes are encoded is the GENETIC CODE. The genetic code comprises of all the codons that specifies amino acids in living organisms. The genetic code has several characteristics, which includes that the GENETIC CODE IS UNIVERSAL
The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.
Answer:
A) To make sure that the effect is not occuring through actions in the nervous system
Explanation:
In the above scenario, researchers actually studies the effect of hormone to the organ but they are in a situation to study the effect on organ are either hormone base or nervous system base (neurons). For this reason they will cut the neurons to study the effect of hormone on the organ.
So, to check the effect of hormone they should cut the neurons to make sure these effect are not due to actions of nervous system.
Answer:
Molluscs have more varied forms than any other animal phylum. They include snails, slugs and other gastropods; clams and other bivalves; squids and other cephalopods; and other lesser-known but similarly distinctive subgroups. Although it is impossible to know the subjective experience of another animal with certainty, the balance of the evidence suggests that most invertebrates do not feel pain. The evidence is most robust for insects, and, for these animals, the consensus is that they do not feel pain. In general, mollusks have 3 body regions: a head, a visceral mass, and a "foot." The head contains the sense organs and "brain," while the visceral mass contains the internal organs. Mollusks usually have a shell (although some do not). Mollusks also have an extension of the body wall called the mantle.
