This is because these characteristics normally have a low survival value for the species. Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and more harmful traits to become rare. This occurs because organisms with advantageous traits pass on more of these heritable traits to the next generation.
Answer: to protect the body from invasion in the gut
Explanation: Gut-associated lymphoid tissue (GALT) is a component of the mucosa-associated lymphoid tissue (MALT) which works in the immune system to protect the body from invasion in the gut.
Answer:
C) Because apoptosis genes kill cells, natural selection is seldom involved in apoptosis pathways.
Explanation:
Apoptosis is a natural process taking in the cell which causes the physiological and biochemical changes in the cell which could cause the death of the cell.
The apoptosis is controlled at the genetic level therefore apoptosis is also known as the programmed cell death.
The studies have shown that the process is involved in the development of the finger and the toes in humans and the sequences controlling the process has been conserved during the evolution in a different organism.
This shows that humans and nematode have the same conserved sequence of apoptosis but the natural selection does not control the apoptosis.
Thus, the selected option is the correct answer.
Answer:
crossing over
Explanation:
Crossing over is where homologs can exchange DNA which leads to genetic variation
