Which pedigree symbol is used to represent a female carrier of a recessive X-linked trait?
xeze [42]
The answer is a half-filled circle. 

In the pedigree charts, squares present males and circles present females. If a female is healthy, the circle is empty (white). If a female is affected with a trait, the circle is filled-in (usually black). However, if a female is a carrier of a disease, which means that one allele is dominant and one is recessive, then the circle is half-filled.

The peripheral nervous system (PNS) transmits information to and from the central nervous system (CNS) and plays a role in regul
kow [346]

Answer:

Neurons in the parasympathetic division release neurotransmitters that act on receptors that slow heart rate

Stimulating the organs of digestion is a parasympathetic response

Parasympathetic nerves are associated with the cranial and sacral regions of the spinal cord, whereas sympathetic nerves are associated with the thoracic and lumbar regions

The sympathetic division of the PNS prepares the body for physical exertion in stressful situations.

Explanation:

The autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates  smooth muscle and glands. Thus, it directly affects the function of internal organs and  regulates  functions such as the heart rate, digestion, respiratory rate,  urination etc. This nervous system control is  unconscious.

The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.
