The parasympathetic division of the autonomic nervous system utilizes <u>acetylcholine</u> as a postganglionic neurotransmitter.

Explanation:

The parasympathetic nervous system consists of both preganglionic (soma in the brain cell/sacral spinal cord) and postganglionic neurons (soma in the ganglion near target organ).

These neurons utilize acetylcholine as the neurotransmitter to transmit the electric nerve signals and produce parasympathetic responses like lacrimation, salivation, sexual arousal, urination and defection at the respective target organs.

Acetylcholine (Ach) can activate the receptors – muscuranic and nicotinic chloinergic receptors.

Pathway of neurotransmission: upon stimulation, ACh released by the preganglionic neuron acts on nicotinic receptors in the postganglionic neurons. Then the ACh released by the postganglionic neuron acts on the muscuranic receptors at the target organ.

Which of the following applies to human skin color?
Bad White [126]

Answer:

A. Heritable

C. Affected by the MC1R gene

D. Polygenic trait

Has evolved due to evolutionary processes such as natural selection.

Explanation:

Human skin color is a polygenic trait as it is regulated by more than one gene. Each allele of these genes has an additive effect on the overall skin color of an individual. Therefore, the trait is a continuous trait, not a discrete one. The genes for human skin color are transmitted from parents to progeny which in turn makes it a heritable trait.

The gene MC1R codes for melanocortin 1 receptor and thereby, regulate the skin color of humans since melanocyte-stimulating hormone binds to the receptor to trigger the synthesis of melanin from melanocytes. Evolution of various skin color in human beings is regulated by natural selection which in turn favors the skin tone best suited under the prevailing climatic conditions of a particular human population

<h3>What causes infectious diseases?</h3>

Coming into contact with a person or an animal who has the virus is one of the most straightforward ways to obtain the most contagious or infectious diseases. Direct contact, such as person-to-person contact, can transfer contagious diseases. Direct transmission of bacteria, viruses, or other germs from one person to another is the primary method by which contagious diseases are typically disseminated. If someone who is unaffected touches, kisses, coughs, sneezes, or has the virus or bacterium on them, this could happen. Additionally, these pathogens can disperse through sexual contact and the exchange of bodily fluids. The person who spreads the infection may only be a carrier and not exhibit any signs of the illness.
