Which of the following is the process by which an organism grows and develops from a zygote to an adult?

  1. Ontogeny

  2. Phylogeny

  3. Meiosis

  4. Mitosis


Correct Option: A
Explanation:

Ontogeny is the process by which an organism grows and develops from a zygote to an adult.

Which of the following is the first stage of embryonic development?

  1. Zygote

  2. Blastocyst

  3. Gastrula

  4. Neurula


Correct Option: A
Explanation:

  1. Senescence

  2. Necrosis

  3. Autophagy

  4. Mitotic catastrophe


Correct Option: A
Explanation:

Senescence is the process by which cells age.

Which of the following is the process by which cells die in a non-apoptotic manner?
