Answer:
A
Explanation:
this is because, in smaller organism their SA/V ratio is large hence they have efficient transport of materials within their cells
Medications can be tested on cell cultures instead of being injected into patients unnecessarily.
Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells.
Answer:
The teeth in the mouth bite off a piece of food.
The teeth continue to break the food into smaller pieces.
Saliva rushes into the mouth and mixes with the broken-down food.
The food travels down the esophagus.
The muscles of the stomach churn the food and continue to break it down.

A testable question is one that can be answered by designing and conducting an experiment. The answers to a testable question can be observed and measured. Hypothesis- a testable explanation of an observation. A hypothesis is NOT just an educated guess about what you think will happen.
When crossing alleles for color, you get
25% pp
50% Pp
25% PP
White flowers are recessive, so there is a 1/4 chance
And when crossing alleles for shape you get
25% rr
50% Rr
25% RR
Wrinkled seeds are recessive so there is a 1/4 chance
Since you are looking for white flowers AND wrinkled seeds, you need to multiply 1/4 x 1/4, giving you a 1/16 chance that the offspring will have these two traits
