Dominant allele is the one which show itself in F1 generation,
If a student made a model of an onion skin cell using a microscopic magnification scale of 500:1 and the length of the modeled cell is 15 cm, the real cell's length would be 0.03 cm.
The scale is 500:1. This means that the dimension of the real cell without being magnified under the microscope would be 1/500.
Thus, if the length of the cell under the microscope is 15 cm. This length has been multiplied by 500. In order to get the real length, it must be divided by 500.
15 x 1/500
= 0.03 cm

If it's the same diagram as mine then it should be the control center of the cell
Chemical messengers, energy providers and cholesterol formation.
Answer:
C: they threaten biodiversity.
They don`t always pollute because they just eat or destroy things in the environment. (Thus "invasive")
Not all are predators. My state has an invasive form or blue reed river algae that kills fish.
Being nonrenewable is mostly irrelevant to the environment.
Hope that helps.
