Answer:
The correct answer would be Gene pool for the population.
A gene pool is defined as the sum total of all the genes present in an inter-breeding population at a specific time.
It includes all the alleles of all the loci within the genes of a interbreeding population or species.
The composition of the gene pool of a population can change with course of a time due to evolution.
A large and diverse gene pool enhances the ability of a population to adapt, survive and evolve in a nature.
Answer: C
Explanation:
If immigration and emigration numbers remain equal, decreased birthrate could cause a slowed growth rate
.
Decreased birthrate always affects the numbers in terms of population.The less births there are, the smaller the number of people. Even if the death rate remains constant a decreased birthrate will slow growth of population.
Answer:A set of five nitrogenous bases is used in the construction of nucleotides, which in turn build up the nucleic acids like DNA and RNA. These bases are crucially important because the sequencing of them in DNA and RNA is the way information is stored.
Answer:
In most eukaryotes, the nuclear envelope fragments, but in diatoms and dinoflagellates, it remains intact.
