The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.
<h3>Cell cycle checkpoints</h3>
There are 3 regulatory checkpoints in the life cycle of cells:
- G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
- G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
- M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.

Answer:
The major organs of the nervous system are the brain, spinal cord, sensory organs, and all of the nerves that connect these organs together.
The nervous system reacts to the presence of danger(instinct), stores memories, control the 5 senses, and commands the rest of the organ systems to maintain homeostasis.
The nervous system works together with the respiratory system, the circulatory system, the muscular system, and many more.

if my answer helps please mark as brainliest.
The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.
The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends.
By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.
There are many ways you can reduce power consumption.
