What is one difference between a primary oocyte and a secondary oocyte in humans

Biology
2 answers:
Monica [59]3 years ago

Answer:

Oocyte refers to the female germ cell which is involved in the process of reproduction.  

In humans, the primary oocyte is diploid in nature, that is, it contains 46 chromosomes as it is formed by mitotic divisions of the oogonium.

In contrast, secondary oocyte is haploid in nature, that is, it contains only 23 chromosomes as it is formed from primary oocyte after it has completed its meiosis I.

Secondary oocyte then undergoes meiosis II to produce a mature ovum.

Is the vagus nerve the heart rate centre of the brain?
koban [17]

Answer:

The vagus nerve has two bunches of sensory nerve cell bodies, and it connects the brain stem to the body. It allows the brain to monitor and receive information about several of the body’s different functions.

Explanation:

The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body.

There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts

The vagus nerve has a number of different functions. The four key functions of the vagus nerve are:

-Sensory: From the throat, heart, lungs, and abdomen.

-Special sensory: Provides taste sensation behind the tongue.

-Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech.

-Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning.

What could be inferred from suntans?
podryga [215]

Answer:

A tan might indicate sun damage to the skin.

Explanation:

Tanning is the process by which the skin is exposed to the ultraviolet rays that comes from the sun with the purpose of producing a dark-brown coloration called a TAN.

A tan achieved by exposure to the sun can actually indicate that a person's skin is undergoing damage from the UV rays of the sun, hence, the skin responds by producing a protein called melanin, which protects the skin and later forms the dark coloration- tan. From this explanation, tan is got in response to a damaging signal received by the cell, hence, a tan might indicate sun damage to the skin.
