Question

the replicated chromosomes are separated by spindle fibres during: *
prophase
metaphase
anaphase
telophase

the interior of the small intestine is lined with *
small hairs that capture dirt.
villi and microvilli that absorb.
slippery, smooth cells so that material moves quickly.
smooth balloon - like bags.

Explanation:

• For the first question:
• In prophase, chromosomes condense, nuclear envelope breaks down, and spindle fibers form.
• In metaphase, chromosomes line up at the equator of the cell.
• In anaphase, sister chromatids (replicated chromosomes) are pulled apart by spindle fibers to opposite poles of the cell.
• In telophase, nuclear envelopes reform around the separated chromosomes.
• For the second question:
• The interior of the small intestine is lined with villi and microvilli. Villi are finger - like projections, and microvilli are even smaller projections on the surface of villi. These structures increase the surface area for absorption of nutrients. Small hairs that capture dirt are more related to structures like cilia in the respiratory tract (for trapping dust etc. in a different context). Slippery, smooth cells for quick material movement and smooth balloon - like bags are not characteristic of the small intestine's lining for its main function of absorption.

Answer:

• First question: C. anaphase
• Second question: B. villi and microvilli that absorb
