Answer:
The individual calcium atom has a positive, not negative, 2 charge.
Explanation:
The error in her study is in the second line of her note which suggests that the individual calcium atoms becomes ions with a negative 2 charge.
- When atom loses electrons, it has a net positive charge on it.
- Not a negative charge.
- This is because the number of protons is now more than electrons.
- Therefore, a net charge on the calcium atom will be a positive one.
- This is her mistake.

The correct answer will be option-A
Explanation:
Cytochalasin is the metabolic product released from the fungus. The cytochalasin acts a toxin to the cell as it inhibits the division of the cell.
Cytochalasin act by inhibiting the cytoplasmic separation during cell division as it blocks the formation of contractile microfilaments. The presence of cytochalasin inhibits the elongation of acing filament as it blocks the addition of the monomer to the growing end of the filament.
Since it prevents the formation of the contractile rings and cytoplasmic separation, therefore, option-A is the correct answer.

Explanation:
Asexual reproduction can be defined as a type of reproduction, in which offspring are developed from a single parent and fusion of gametes does not take place.
As it involves only one parent that contributes to the all of the genetic material of offspring, the offspring are genetically or physically similar to their parents.
Thus, the correct answer is option) C.
