Adisadvantage of asexual reproduction is that offspring lack ; therefore, all the offspring are vulnerable to attack by the same diseases or pests.
a. cotyledons
b. genetic variation
c. radicles
d. cuticles

B. Genetic variation

Explanation:

New combinations of genes and alleles impart genetic variations to the offspring produced by sexual reproduction. These new gene combinations are produced during meiosis and fusion of male and female gametes. Some of these genetic variations become beneficial under certain conditions and increase the chances of survival of the species under unfavorable conditions.  

Asexual reproduction includes a single parent. It does not involve the fusion of male and female gametes. Therefore, the progeny produced by asexual reproduction is genetically identical to the single parent and lack any genetic variations. The absence of genetic variations makes this progeny prone to be adversely affected by any biotic or abiotic disturbances such as diseases.  

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
