There are no choices available, however, the possible environmental risk that this situation can give is the depletion of ground water. The amount of water being pumped out from the ground will take time to replenish, hence emptying ground water and possibly mixing sediments trapped inside the cavern of water. This situation can eventually contaminate new ground water that will seep in into the cracks that were dug for irrigation.
Answer:
D. The offspring of multi-cellular organisms tend to be identical to the parent.
Explanation:
The offspring of multi-cellular organisms which reproduce through sexual mode can never be identical to the parents because of <u>crossing over</u> which is a phenomenon which occurs during <u>meiosis</u>. All the individuals which have sexual dimorphism and reproduce sexually have germ cells in their gonads. Meiosis is a type of cell division which occurs only in germ cells not in somatic cells. <u>During meiosis the genetic material from both the parents is exchanged leading to new combinations of genes</u> as a result of which offspring is neither 100% identical to father nor to the mother. Offspring displays traits which are a combination of both the parents thereby showing variability.
If you change more than one variable at a time, then you will have a harder time trying to figure out why the certain change occurred.
Explanation:
Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both.
Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients while Chloroplast is the site for photosynthesis in a plant cell.
The best description of chromosomes by the end of metaphase 2 of meiosis is that they are lined up in the middle of the cell. You can help remember this by thinking of the "M" in metaphase as middle. this is because in this phase the chromosomes are lined up in the middle of the cell.
