Question 4

A scientist crosses two pea plants, one with genotype $$Tt ($$tall) and one with genotype $$tt ($$short). What is the expected phenotypic ratio of their offspring?

Accepted Answer

1 tall : 1 short

Question 5

Which of the following best explains why natural selection leads to evolution?

Accepted Answer

It increases the frequency of beneficial heritable traits in a population over generations.

Question 6

Which metric unit would be most appropriate for measuring the diameter of a typical animal cell?

Accepted Answer

Micrometer ($$\mum)$$

Question 7

During which phase of mitosis do sister chromatids separate and move toward opposite poles of the cell?

Accepted Answer

Anaphase

Question 8

A student is asked to explain the difference between osmosis and diffusion. Which statement is correct?

Accepted Answer

Osmosis is the movement of water across a selectively permeable membrane, while diffusion is the movement of molecules from high to low concentration.

Question 9

Which of the following best describes the role of DNA in protein synthesis?

Accepted Answer

DNA is transcribed into RNA, which is then translated into protein.
