Answer:
A
Explanation:
a. contain checkpoints that determine if the cycle will continue.
b. help move chromosomes to the new daughter cells.
c. produce more chromosomes before the cell divides.
d. grow and produce enough cytoplasm to fill two cells.

<em>The correct answer would be that G1 and G2 contain checkpoints that determine if the cycle will continue or otherwise.</em>
The cell cycle generally has three checkpoints that happen at G1, G2, and M phase of the cycle.
At G1 checkpoint, the integrity of the DNA of the cell is assessed to ensure that there are no damages and other conditions such as size and energy reserve are checked.
At G2 checkpoint, the cell is assessed for proper chromosome duplication to ensure that there are no mistakes or damages. The size of the cell and the amount of protein are also checked to ensure that the cell is ready for the active division phase.
At M checkpoint, correct attachment of the spindle fiber to the kinetochore of the chromosomes is checked. This checkpoint is also known as the spindle checkpoint and it happens towards the concluding phase of the metaphase stage.
<u>The correct option is therefore, A.</u>
Answer:
The answer is C.
Explanation:

Answer:
Causes. Three main causes of ecological succession are identified for the process of succession. Initiating causes - The initiating causes include biotic and climatic factors which destroy the existing populations of the area. The climatic factors include wind, fire, natural disasters, erosion, etc.

<h2>
Answer:</h2>
<u>B. Spores</u> are involved in both sexual and asexual reproduction.
<h2>
Explanation:</h2>
In science, a spore is a unit of sexual as well as asexual proliferation that might be adjusted for dispersal and for endurance, frequently for expanded timeframes, in troublesome conditions.
Bacterial spores are not part of a sexual cycle but rather are safe structures utilized for endurance under horrible conditions. Under good conditions, the spore can form into another living being utilizing mitotic division, delivering a multicellular gametophyte, which inevitably proceeds to create gametes.
Answer:
<em>The correct option is "a discussion of any errors in the experimental data"</em>
Explanation:
The analysis section of a lab report describes the critical analysis of the experiments and observations that were carried out. It also describes the defaults in any observational method which they got to know during the experimental method. The analysis section also tells how the experimental and observational methods could be made better. Hence, we can say that the analysis section of a lab report shows discussion of any errors in the experimental data.
