Answer:
Explanation:
1. a. Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During interphase, the cell copies its DNA in preparation for mitosis.
b. The third phase is anaphase. This phase only takes about 0.8 percent of the cell cycle to complete, which is the shortest time required out of all the phases. During anaphase the sister chromatids, or the two identical parts of a chromosome, are pulled apart to opposite ends of the cell by the spindle fibers.
2. Mitosis is important for three main reasons: development and growth cell replacement and asexual reproduction.
- Development and growth. After meiosis has produced a gamete, and this has fused with another gamete to form an embryo, the embryo grows using mitosis. ...
- Cell replacement. ...
- Asexual reproduction.
Answer:
Explanation:
What Mendel wanted to happen was to obtain middle-sized plants. What actually happened was that Mendel got tall plants. Due to this result, Mendel called Reccesive to the genes thatdetermined the short offspring, and Dominant to the genes that determined the tall offspring.
The correct answer is C incomplete dominance, because the pink flowers represent a third phenotype. Incomplete dominance<span> is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over the other allele which results in the formation of a third phenotype, which in this case is the pink flowers:)</span>
Cell division and differentiation first begins during the germinal stage of prenatal development.
<u>Explanation:</u>
The development of the zygote into a full developed fetus occurs in three most prominent stages they are the germinal stage that occurs from the conception to the second week.
The embryonic stage that is from second week to the eighth week and the fetal stage that is from the eighth week till the birth of the baby. Each stage has its characteristic development that has to be completed.
C. Australia was covered in ice during a key geologic period.
at the time of coal forming, Australia was closest to the south pole, so it was too cold.
