Which of the following statements about apoptosis is false? a. It is an important process in the development of human fingers and toes. b. Despite more than 600 million years of evolutionary divergence, humans and nematodes share similar apoptosis pathways. c. Because apoptosis genes kill cells, natural selection is seldom involved in apoptosis pathways. d. All of the above are true; none is false.

Respuesta :

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.

The following statements about apoptosis is false - c. Because apoptosis genes kill cells, natural selection is seldom involved in apoptosis pathways.

Apoptosis is a form of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes and death.

  • The major components of the programmed cell death pathway are conserved between Caenorhabditis elegans, Drosophila melanogaster, and humans.
  • The genetic basis for apoptosis pathways has been conserved during animal evolution.
  • the hand started out as a paddle-like block of tissue when you were an embryo. The block turns into fingers by apoptosis of the cells in between the developing fingers.

Thus, The following statements about apoptosis is false - c. Because apoptosis genes kill cells, natural selection is seldom involved in apoptosis pathways.
