Question 1

Which of the following statements best describes the outcome of mitosis in a diploid eukaryotic cell?

Accepted Answer

Two daughter cells, each genetically identical to the parent cell and to each other.

Question 2

During which process do homologous chromosomes pair up and exchange genetic material, increasing genetic diversity?

Accepted Answer

Meiosis I

Question 3

A certain protozoan spends most of its life cycle as a haploid organism. What does this mean about its chromosomes?

Accepted Answer

It has one copy of each chromosome.

Question 4

Which of the following best explains why meiosis results in genetically unique daughter cells?

Accepted Answer

Crossing over and independent assortment occur during meiosis.

Question 5

If a diploid cell with $$2n = 8$$ chromosomes undergoes mitosis, how many chromosomes will each daughter cell have?

Accepted Answer

$$8$$

Question 6

Which of the following is a key difference between mitosis and meiosis?

Accepted Answer

Mitosis results in genetically identical cells, while meiosis results in genetically diverse cells.

Question 7

In which scenario would you expect to find multiple rounds of mitosis without cytokinesis, resulting in a multinucleated cell?

Accepted Answer

Schizogony

Question 8

A fungal cell undergoes budding. What is the most likely outcome?

Accepted Answer

One large and one small daughter cell due to unequal division of cytoplasm.

Question 9

Which of the following equations correctly represents the chromosome number in daughter cells after meiosis, if the parent cell is diploid with $$2n$$ chromosomes?

Accepted Answer

$$n$$

Question 10

Why are the products of meiosis not genetically identical to each other?

Accepted Answer

Because of crossing over and independent assortment during meiosis I.

Question 11

Which of the following best describes cytokinesis?

Accepted Answer

Division of the cytoplasm.

Question 12

If a diploid organism has $$2n = 12$$ chromosomes, how many chromosomes will each cell have after meiosis II?

Accepted Answer

$$6$$

Question 13

Which of the following is true about the life cycles of most eukaryotes?

Accepted Answer

They alternate between haploid and diploid stages.

Question 14

A scientist observes a cell with multiple linear chromosomes and a nucleus. Which type of organism is this cell most likely from?

Accepted Answer

Eukaryote

Question 15

Which process is responsible for producing gametes in animals?

Accepted Answer

Meiosis

Question 16

In a medical scenario, a patient is diagnosed with a parasitic infection caused by a protozoan that reproduces by schizogony. What is a key feature of this reproductive process?

Accepted Answer

Multiple rounds of mitosis without cytokinesis, followed by a single cytokinesis event.

Question 17

Which of the following best explains why mitosis is important for multicellular organisms?

Accepted Answer

It allows for growth and repair by producing genetically identical cells.

Question 18

During which stage of meiosis does crossing over typically occur?

Accepted Answer

Prophase I

Question 19

If a cell undergoes mitosis but fails to complete cytokinesis, what is the most likely result?

Accepted Answer

A single cell with two nuclei.

Question 20

Which of the following is a real-world example of an organism that is haploid for most of its life cycle?

Accepted Answer

Fungus
