In metaphase, anaphase and telophase of meiosis 2 before cytokinesis the condition prevails.
Explanation:
Meiosis is the cell division process that occurs in gamete precursor cells to create gametes. It's a reduction division since the progenitor cells are diploid while the gametes are haploid.
During meiotic division, the cells first go through DNA replication that doubles the DNA content of each chromosome.
Then, via meiosis I, the cell experiences reduction division, transforming the diploid cell into a haploid cell. Thus, a cell with 10 chromosomes becomes one with 5 chromosomes. However, the DNA amount per chromosome remains doubled. This is corrected by the second meiotic division, where each chromosome splits into chromatids with a standard DNA content.
So at each stage of meiosis II,
until cytokinesis occurs, the cells should remain in a haploid state with double the DNA content. [[TAG_45]]
By applying Kepler's third law of planetary motion, we understand that the square of the orbital period corresponds to the cube of the semi-major axis. Given that Earth orbits at 1 AU with a 1-year period, we can establish the ratio:
P^2 / r^3= 1
(P)^2 = 4^3
<span>P = 4^(3/2) = 8 years </span>
Answer:
100 units
Explanation:
The parent cell holds 200 units of DNA. During the process of cell division, this amount is distributed between the resulting daughter cells, with each cell obtaining half of the DNA present in the original cell.
As mitosis yields two daughter cells, each one will receive 100 units of DNA.
The answer involves the regulation of activity by higher brain centers. Explanation: The autonomic nervous system, part of the peripheral nervous system, manages involuntary functions that occur without conscious control, such as heart rate and breathing. Conversely, the somatic nervous system is also part of the peripheral nervous system but transmits signals to skeletal muscles and receives stimulus information. While both systems differ, they are not responsible for regulating activity by higher brain centers.
