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.

It will have no effect because the order in which ingredients are mixed will not change the fact that matter cannot be created nor destroyed.
<h3>Effect occurs on mass</h3>
The order in which we add the ingredients do not affect the mass of the batter because the order in which ingredients are mixed will not change the fact that matter cannot be created nor destroyed.
The mass of the batter remains the same due to the incorporation of same quantity of ingredients so we can conclude that option A is the right answer for this question.

The answer to this question would be: insulin
Insulin is a hormone that produced by the pancreas. Insulin makes sugar go inside cells. Sugar is the food for cells. Without insulin, the sugar can't enter the cell and the cell food is depleted. This will cause the body feel that the sugar is not enough and trying to increase the sugar concentration. This will result in the increases of blood sugar level.
Meiosis a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
It is useful for an ecologist to identify the keystone species in an ecosystem because the keystone species is important to maintaining the stability of an ecosystem, and any changes in the keystone species population shows that there is changes in ecosystem health.
