Accepted Answer

Prokaryotic cell

Question 3

Accepted Answer

Metaphase

Question 5

Which of the following is a real-world example of diffusion in biological systems?

Accepted Answer

Oxygen moving from alveoli into blood capillaries in human lungs

Question 6

A geneticist is studying a trait controlled by a single gene with two alleles, one dominant (A) and one recessive (a). If two heterozygous individuals (Aa) mate, what is the expected genotypic ratio of their offspring?

Accepted Answer

1 AA : 2 Aa : 1 aa

Question 7

Which principle of evolution explains why antibiotic resistance in bacteria increases over time in a hospital setting?

Accepted Answer

Natural selection

Question 8

Which of the following best describes the function of enzymes in biological reactions?

Accepted Answer

Enzymes lower the activation energy, speeding up chemical reactions.

Accepted Answer

Plantae

Question 13

Which of the following statements about meiosis is correct?

Accepted Answer

Meiosis results in four haploid cells from one diploid cell.

Question 14

Accepted Answer

Natural selection

Question 15

Which of the following is a correct statement about genetic principles?

Accepted Answer

Dominant alleles always mask recessive alleles in heterozygotes.

Question 16

Which of the following is an example of a biotic factor in an ecosystem?

Accepted Answer

Soil bacteria

Question 17

A student is asked to calculate the magnification of a microscope using the following formula: $$	ext{Total Magnification} = 	ext{Objective Lens Magnification} 	imes 	ext{Ocular Lens Magnification}. If $$the objective lens is 40x and the ocular lens is 10x, what is the total magnification?

Accepted Answer

$$400$$
