How does the number of chromosomes in the daughter cells of meiosis different from those in mitosis?

Biology
1 answer:
pashok25 [27]3 years ago
7 0

Answer:

In meiosis, chromosome number in daughter cells is reduced by half while in mitosis the chromosome number doesn't change.

Explanation:

In mitosis there is a single cell division, while in meiosis there are 2 cell divisions.

In both cases the process start with the replication of DNA, so each chromosome has two sister chromatids.

  • In mitosis, the sister chromatids separate, resulting in two daughter cells identical to the original cell, before the DNA replicated.

  • In meiosis, homologous chromosomes separate during the first cell division, giving two daughter cells with half the chromosome number of the original cell, but each of them still has two chromatids. During the second cell division the chromatids separate, resulting in a total of four daughter cells, each with half the chromosomes than the original one.

What is semi-conservative DNA replication and how does it differ from conservative replication? Which type of DNA replication is
fredd [130]

Answer:

Semi-conservative DNA replication:

The semi-conservative model of DNA replication explains that the newly synthesized daughter DNA molecule contains one newly synthesized strand and one parental strand. This model of replication is important and explains the biological significance of replication. The DNA unwinds in this mode of replication.

Conservative model of DNA replication:

The conservative model of DNA replication explains that the newly synthesized daughter DNA molecules has the one DNA helix of parent and the other DNA helix are entirely new. This model does not has a biological significance. The DNA is not unwinds in this mode of replication.

The semi-conservative mode of DNA replication is found in the living organism.

Which energy system can power an all-out effort from 3 to 10 seconds? oxygen atp-cp lactic acid nad
Anon25 [30]

The correct option is (b) ATP-CP.

ATP-CP stands for Adenosine Triphosphate Phosphocreatine.

<h3>What makes ATP and ATP CP different from one another?</h3>

ATP exhausts its energy after roughly 1-2 seconds. The high-energy links that hold the CP (creatine/phosphate) molecule together are utilised in subsequent studies. Energy is released when these bonds are broken. ATP is once more formed when the energy is used to rejoin the phosphate to ADP.

<h3>Why is ATP CP so important?</h3>

The ATP-PC system provides energy to the muscle fibers with the highest threshold, which can exert the maximum force. Larger, stronger muscles should have higher power because they can store more phosphocreatine.

Based on the diagram below, which part of an atom has the greatest mass?
Juli2301 [7.4K]
The nucleus will have the greatest mass. Among the 3 kinds of subatomic particles, electrons are the lightest (by several orders of magnitude), protons and neutrons are much closer is magnitude, though neutrons are slightly heavier. However, in the diagram, the nucleus contains both the neutrons and the protons, so its combined mass would be heavier than either the neutrons alone or the protons alone.
