What is produced by the process of meiosis?
lara31 [8.8K]
Choice C is correct. 

WHY: In meiosis, sex cells (eggs or sperm) are produced. This means that they must have <u>half </u>the number of chromosomes in each, and they must be each <u>UNIQUE</u>.
Thus, the other options (A,B,D) cannot be correct because the product of meiosis cannot be the exact copy of the parent cells, and so cannot have the same number of chromosomes either.

After watching the video on flooding, what would be a major change that can
Delicious77 [7]

Answer:

Both

Explanation:

Depends on what happened in that video. I would rewatch it and write about what the video said about flooding and relate it to the river. Could be an ice jam or something else slowing the flow of water suddenly opened up. A breaking dam? Flash floods from an abundance of rain. As the amount of water in the river increases, so does the flow rate. If the amount of water suddenly increases more than the river was used to/it could hold, it will flood.

Rewatch the video and see if this relates at all :)

Dovator [93]

Answer:

Outcome variable (dependent variable)

Explanation:

In a scientific investigation, a DEPENDENT VARIABLE (also known as outcome variable) is the variable that is being measured. The dependent variable, as the name implies, responds to the changes made to the independent variable.

For example, in an experiment where the effects of different concentration of fertilizer is used to test plant growth (height), the HEIGHT OF THE PLANTS is the dependent variable because it is the variable being measured.
