Answer:
Sympatric speciation.
Explanation:
Sympatric speciation is a type of speciation that occurs when 2 types of groups of the common species live in the common geographic location, but they grow differently until they can no longer interbreed and are known as different species.
This speciation can occur in different types of species such as bacteria, the apple maggot fly, and cichlid fish, but it is difficult to tell when this speciation is happening or has occurred in nature. There are four types of speciation occurs:
1) Symmetric
2) Allopathic
3) Parapatric
4) Peripatric.
C) ribosomes and mitochondria
The tertiary structure of a protein refers to the overall three-dimensional arrangement of its polypeptide chain in space. It is generally stabilized by outside polar hydrophilic hydrogen and ionic bond interactions, and internal hydrophobic interactions between nonpolar amino acid side chains
I think it should be 24, for there are 48 chromosomes in each cell
The answer is semiconservative replication. Semiconservative meaning that half of the original molecule (one of the two strands in the double helix) is conserved in the new molecule. Replication is the process by which double stranded DNA molecule is copied to produce two identical DNA molecules. It is one of the most basic process that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each stand of existing DNA acts as a template for replication.
