A teacher explains to her students that during mitosis, all the cells divide into two daughter cells and each daughter cell has the same number of chromosomes. The teacher asks her students to support this explanation. What statements should the students give?
During mitosis, cells divide continuously without growing.
During the growth phase between two mitotic divisions of a cell, chromosomes and the cytoplasmic organelles duplicate.
Each daughter cell receives exactly half the number of duplicated chromosomes.
Each daughter cell receives half the chromosomes and the cytoplasmic organelles from the parent cell and then duplicates.
Which statement below is an example of active transport?
The LDL (low-density lipoprotein) from a human body carries cholesterol, which binds to LDL receptors on the cell surface.
The gills of a marine fish remove salt from the fish's body by pumping it into the ocean water.
The root hair cells of a plant absorb the higher concentration of water from the soil into the plant's body.
The digestive enzymes of a bear are secreted from cells that line the inner surface of various exocrine glands.

The root hair cells of a plant absorb the higher concentration of water from the soil into the plant's body.
The LDL (low-density lipoprotein) from a human body carries cholesterol, which binds to LDL receptors on the cell surface.
