Answer:
Explanation:
a) Drug X binds to the secondary site or co-agonist site of the receptor since it has no effect on contraction.
b) Drug Y binds to the primary site or agonist site of the receptor since it elicits contraction when aorta is exposed to it.
c) Drugs X and Y have a synergistic effect because the sum of their forces measured independently is larger than when they are tested simultaneously.
The answer is A.) Sister chromatids of the same chromosome! Hope this helps dear! and if u can please put me as Brainliest! thanks
This could help the elephant population rebuild by taking away some of its (predators). Elephants are a keystone species because they dig watering holes, which all animals need. You increase the number of elephants, you increase water availability.
A frameshift mutation is a kind of mutation which is most likely to lead to a new trait in an organism. Thus, the correct option is A.
<h3>What is Mutation?</h3>
A Mutation may be defined as the sudden, stable, and inheritable alterations in the genomic sequence of an organism.
A frameshift mutation occurs when the reading frame modifies the grouping of the bases and thereafter transforms the amino acids that are encoded. Here, the encoded protein is non-functional.
A missense mutation arises when there is a blunder in the DNA code and one of the DNA base pairs is altered.
A nonsense mutation occurs when a single change in the base sequence outcomes in the exhibition of a stop codon, thereby concluding protein synthesis prematurely.
Therefore, it is well described above.
