Answer:

<em>The correct option is A. mitospore</em>

Explanation:

A mitospore can be described as a haploid or diploid spore. Generally, a spore is formed by meiosis but under certain conditions it can form by the process of mitosis and is known as mitospore.

When spores are formed by sexual methods, meiosis occurs. When they are formed by asexual methods, mitosis occurs. Asexually, there are different ways by which mitospores form by mitosis.

What is the part of the cell cycle process by which chromosomes in a cell nucleus are separated into two identical sets of chrom
Damm [24]

Answer:

Mitotic phase

Explanation:

Cell cycle is composed of interphase and mitotic phase. Interphase is aphase of cell preparation. It is subdivided into:

  • G1 (gap 1 phase)-the cell grows and becomes larger
  • S phase- replication of DNA, duplication of centrosomes
  • G2 (gap 2 phase)-proteins and oranelles are made

Mitotic phase is phase of cell division, chromosomes are separated, daughter cell get identical sets of chromosomes. It is followed by cytokinesis-separation of cytoplasm. Stages of mitosis are:

  • prophase-condensation of chromatin into chromosomes,  the nuclear envelope breaks down, mitotic spindle formation
  • metaphase-the chromosmes line up (metaphase plate)
  • anaphase-the siste chromatides move toward opposite cell poles
  • telophase-the nuclear envelope forms again, cell division is almost complete

What is the main prerequisite for clearance at the G2 checkpoint?
Katena32 [7]

Answer:

The correct answer will be option-accurate and complete DNA replication.

Explanation:

The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.

The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.

Thus, option-accurate and complete DNA is the correct answer.

NNADVOKAT [17]
The mechanism that affected the gene pool of the immigrants that entered the United states Through Ellis Island is Gene flow.

Gene flow involves the movement of genes or alleles between interbreeding populations of a particular species. In other words it is the movement of genes from one population to another population. Actually it may be an important aspect of evolution; evolution can occur as a result of genes being transferred from one population to another. Gene flow occurs when there is migration, since the loss or addition of people can easily change pool frequencies even without no other evolutionary mechanisms operating.
