Answer:
A) once, during interphase I
Explanation:
Although meiosis has two phases, the chromosome replicate only once during interphase I. The DNA material replicates and cell builds up enough energy stores to drive the process through. Other events that occur during interphase are formation of new organelles including centrioles.
Answer:
an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Explanation:
An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge. In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species
Both mitosis and meiosis are a cell division process having various similarities and differences.
Similarities between the process of mitosis and meiosis include:
- Both the processes are cell division process.
- Both the processes occur in the nucleus of a cell.
- Both the processes result in the formation of daughter cells.
- The main phases are the same in both the processes
The differences between mitosis and meiosis include:
- As a result of mitosis, two daughter cells are formed. As a result of meiosis, four daughter cells are formed.
- The process of mitosis occurs in somatic cells whereas the process of meiosis occurs in reproductive cells.
- The daughter cells formed as a result of mitosis are the exact copies of parent cell. In the process of meiosis, genetic recombination occurs and hence the daughter cells are not exact copies of parent cells.
