Question 1

Which of the following best describes the hierarchical organization of the human body from simplest to most complex?

Accepted Answer

Cells → Tissues → Organs → Organ Systems → Organism

Question 2

Which organelle is primarily responsible for producing ATP, the energy currency of the cell?

Accepted Answer

Mitochondrion

Question 3

During which phase of mitosis do chromosomes align at the center of the cell?

Accepted Answer

Metaphase

Question 4

Which of the following statements about meiosis is correct?

Accepted Answer

Meiosis produces four haploid daughter cells, each with half the genetic material of the original cell.

Question 5

Which cell structure is responsible for packaging and transporting proteins within the cell?

Accepted Answer

Golgi apparatus

Question 6

A mutation prevents the formation of spindle fibers during mitosis. Which stage would be directly affected?

Accepted Answer

Anaphase

Question 7

Which of the following best explains why muscle cells contain more mitochondria than skin cells?

Accepted Answer

Muscle cells require more energy for contraction, so they need more ATP.

Which of the following is NOT a function of the cell membrane?

Accepted Answer

Synthesizing proteins

Question 9

If a cell is unable to produce ribosomes, which process would be directly impaired?

Accepted Answer

Protein synthesis

Question 10

Which of the following best describes the role of epithelial tissue in the body?

Accepted Answer

It forms protective barriers and lines body surfaces.

Question 11

Which phase of meiosis is responsible for the separation of homologous chromosomes?

Accepted Answer

Anaphase I

The division of the cytoplasm to form two separate daughter cells

Question 16

Which of the following is a function of nervous tissue?

Accepted Answer
