Lateral gene transfer, also known as horizontal gene transfer, increases genetic diversity and plays a big role in evolution of single celled organisms.
The correct answer would be C) The genetic variation will increase.
Horizontal or lateral gene transfer refers to the transmission of genetic material between two different genomes which is distinguished from a transfer of genetic material from parent to the offspring that is, vertical gene transfer.
For example, transformation, transduction, and conjugation result in horizontal gene transfer in bacteria.
It increases genetic variation of the population and plays important role in adaptation as well as evolution.
A heterotroph is an organism that ingests or absorbs organic carbon in order to be able to produce energy and synthesize compounds to maintain its life.
I think this is the answer. It may be autotroph if im wrong.
B. Oxidation of food through the process of cellular respiration
Explanation: During cellular respiration oxygen molecules combines with glucose and forms ATP or adenosine triphosphate an energy giving molecule to sustain cellular activities.
Stretching of the atrial muscle cells releases a hormone called atrial natriuretic factor (ANF). ANF relaxes the juxtaglomerular (JG) cells of the afferent arteriole and thereby increases GFR and urine output.
