For fertilization to occur in humans, only one sperm is needed to weaken the barrier that surrounds the egg.
photoshop1234 [79]

Answer:

False

Explanation:

Approximately 200 out of 200 million sperms ejaculated during intercourse reach the general vicinity of the egg.  They sperms must undergo capacitation during which dilute inhibitory factors fluids of the female reproductive tract weaken the membrane of the sperm head so that head of the sperm can be broken easily when it came in contact with the egg.

The first sperm to reach an egg isn’t the one to fertilize it because the egg is surrounded by a gelatinous membrane called the zona pellucida. Outside this layer, a layer of small granulosa cells also present.

Therefore, it requires numerous sperm to clear a path through these barriers before one of them can penetrate the egg and fertilize it.

Which function of the integumentary system is illustrated in the release of sweat? A. Absorption B. Protection C. Sensory Recept
ladessa [460]

Answer:

F. Both regulation and secretion

Explanation:

Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.

The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.
