Answer:

1.Sexual reproduction couldn't happen without the sexual organs called the gonads. Most people think of the gonads as the male testicles. But both sexes have gonads: In females the gonads are the ovaries, which make female gametes (eggs). The male gonads make male gametes (sperm).

2.The pores in your skin contain oil glands. When you hit puberty, there's an increase in sex hormones called androgens. The excess hormones cause your oil glands to become overactive, enlarge, and produce too much oil, or sebum. When there's too much sebum, the pores or hair follicles become blocked with skin cells.

3.Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)

4.Reproduction is important for the survival of all living things. Without a mechanism for reproduction, life would come to an end. ... Asexual reproduction refers to simple cell division that produces an exact duplicate of an organism.
