What is the question your trying to have answered?
A terrestrial ecosystem is a land-based community of organisms.
Answer:
The correct answer is option B) "a deletion of two nucleotides".
Explanation:
A frameshift mutation is a type of genetic modification caused by the insertion or deletion of one or more nucleotides in a position that results in changing the sequence at which codons are translated in the ribosome. Frameshift mutations have the most serious effect on the polypeptide products since it results in changing completely the sequence of the protein. A deletion of two nucleotides after the AUG start of translation would result in a frameshift mutation, therefore this mutation would have the most serious effect on the polypeptide product.
In enzymes, structure determines function, so if you denature the enzyme (mess with the structure), then the function will most likely be lost. Also, most enzymes are very specific for a certain substrate. The substrate is the key and the enzyme is the lock.
Global can harm animals that are not likeli to change their environment parameters, such as humans can go from desert to tundra, but for example lions cannot live in tundra. Animals that need lower temperature won't live in higher one, such as polar bears or penguins.
