Which statement best explains how each of the different cell types can develop from the same embryo?

• The cells have identical genetic instructions, but different parts of these instructions are being expressed in each cell.

• The cells have identical genetic instructions, and all parts of these instructions are being expressed in each cell.

• The cells are produced by asexual reproduction and contain identical genetic instructions.

• The cells contain genetic instructions from two different parents and will express the instructions from one parent, only.

When an organism reproduces asexually, it usually has

• only one parent, and half as much DNA as the parent

• only one parent, and the same chromosome number as the parent

• two parents, and twice as much DNA as either parent

• two parents, and the same chromosome number as each parent

When a paramecium, a single-celled organism, is living under stressful conditions, it sometimes switches from asexual to sexual reproduction. The main advantage when this switch occurs is that the paramecium is most likely to

• produce fewer offspring

• increase variation among its offspring

• avoid having to find a mate

• produce clones of itself

Which statement describing this diagram is correct?

• The cell represented by structure 3 has the same genetic content as structure 2.

• Process A represents the process of meiosis.

• Each cell in structure 4 has the same genetic content as that in structure 3.

• Processes A and B both occur in the placenta.

Which statement describes a function of the hormone estrogen?

• It regulates the secretion of digestive enzymes.

• It promotes sperm production in males.

• It influences the development of adult sex characteristics.

• It maintains blood sugar levels.

The primary function of the human male reproductive system is to

• provide a site for fertilization

• produce and transport gametes

• protect and nourish the embryo

• prevent urine from leaving the body

If blockages of this type occur, the most likely result would be that

• the egg would remain in the uterus and not travel upward

• the female gamete would not be able to unite with the male gamete

• hormones could not be produced by the ovaries

• the process of asexual reproduction would be prevented or interrupted
