Level 2 Compare and Contrast: Which of the following characteristics applies to only meiosis?

The new cells are used for reproduction

The new cells have the same amount of DNA as the original cell

What is the claim made about the effect of caffeine on root growth?

Caffeine decreases root growth by damaging DNA and preventing mitosis.

Caffeine increases root growth by speeding up mitosis.

Caffeine has no effect on root growth.

Caffeine helps roots absorb more nutrients.

Why does exposure to chemicals like caffeine reduce average root growth, according to the claim?

Because caffeine damages DNA and prevents cells from completing the cell cycle.

Because caffeine increases the rate of photosynthesis.

Because caffeine provides more nutrients to the roots.

Because caffeine causes roots to grow in different directions.

If you were to design an experiment to test the effect of a new chemical on root growth, what would be an important control to include?

Use a group of plants that receives no chemical treatment.

Only use the new chemical on all plants.

Change the amount of sunlight for each group.

Use different types of soil for each group.

A researcher is calculating the mitotic index for normal and cancerous cells. The table shows the number of cells in different phases of the cell cycle. Which of the following is the correct first step in calculating the mitotic index for both normal and cancerous cells?

Add the number of cells in mitosis (prophase, metaphase, anaphase, and telophase) for each tissue type.

Divide the number of cells in interphase by the total number of cells observed.

Subtract the number of mitotic cells in normal tissue from the number in cancerous tissue.

Multiply the total number of cells by 100 to find the mitotic index.

How does the corpse flower’s reproductive strategy rely on genetic variation for pollination success?

They use pollinators to obtain pollen from other plants that will fertilize their ovules with fresh genetic material.

The corpse flower produces genetically identical clones to ensure that all pollinators are attracted to the same scent.

The corpse flower uses mitosis exclusively to create pollen, leading to more consistent pollination rates.

Genetic variation in the corpse flower has no impact on pollination, as it relies solely on environmental factors for reproductive success.

Which process is used by plants to create offspring?

Both asexual and sexual reproduction

Which of the following statements best describes the main difference between mitosis and meiosis?

Mitosis produces identical cells; meiosis produces genetically different cells.

Mitosis occurs only in animals; meiosis occurs only in plants.

Mitosis requires two parents; meiosis requires one parent.

Mitosis produces gametes; meiosis produces body cells.
