C. the amount of rain falling on the cactus plants

Explanation:

The amount of rain falling on the cactus plant is the independent variable in this experimental design.

The height of the cactus plant is the dependent variable here.

  • An independent variable in an experiment is the cause of a change.
  • The dependent variable is the effect of the change produced.
  • The amount of rain that falls affects the growth of the cactus plant.
  • This is clearly the independent variable in this design.

How many ova, plural for ovum, can be produced from two primary oocytes through meiosis?
ivann1987 [24]

Answer:

b. 2

Explanation:

Each primary oocyte produces 4 daughter cells after meiosis. However, only one of those 4 cells is an ovum;the three remaining cells are called polar bodies. Polar bodies are not ovulated and therefore are not fertilized.

According to the above, if we have two primary oocytes, we will obtain two ova after meiosis.
