No the right answer is A. Homeostasis allows organisms to regulate their temperature because it makes sure the organisms cells do not burst or shrink. This allows the organism to survive.
Answer:
In a chemical equilibrium, the forward and reverse reactions occur at equal rates, and the concentrations of products and reactants remain constant. A catalyst speeds up the rate of a chemical reaction, but has no effect upon the equilibrium position for that reaction.

C. They unwinds the two strand of DNA.
The concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.
<h3>What is the endosymbiotic theory?</h3>
The endosymbiotic theory is a well-sustained theory in biology about the origin of eukaryotic cells.
According to this theory, eukaryotic cells emerged by endosymbiosis between primitive eukaryotic cells and bacteria that converted into mitochondria and chloroplast organelles.
The endosymbiotic theory is well sustained in several scientific observations such as the existence of DNA in mitochondria and chloroplasts that is independent of nuclear DNA, the size of ribosomal units, etc.
In conclusion, the concept presented to explain the origin of eukaryotic cells form a bacterial cell parasitized by another descendant cell is called endosymbiosis.

Recessive alleles. Recessive alleles are only expressed phenotypically when the offspring receive recessive genes from each parent. In other words they are only expressed phenotypically when they occur in pairs. In the presence of dominant gene they are never expressed phenotypically and the offsprings with both the recessive and dominant genes occurring concurrently are referred to as carriers.
