Preganglionic Neruons, Conduct impulses from the brain/spinal cord to the ganglion. Both SNS and PNS preganglionic neurons release Acetylcholine (Ach) as their neurotransmitter and Receptors are Cholinergic. Postganglionic Neurons conduct impulses from the ganglion to the effector organ or tissue.

An increased rate of breathing as a result of an increased buildup of carbon dioxide in the bloodstream would be best described

ValentinkaMS [17]

Answer;

Responsiveness

Excretion

Explanation;

Excess carbon dioxide must be removed from the body to stop it reaching toxic levels. As the blood flows through the lungs, excess carbon dioxide passes out of the blood and into the alveoli by diffusion. It is then removed from the lungs when we exhale (breathe out).

-Carbon dioxide helps remove carbon dioxide (a waste gas that can be toxic) from your body. The lungs' intake of oxygen and removal of carbon dioxide is called gas exchange. Gas exchange is part of breathing.

3. In what possible scenario would the female birds evolve to having the singing trait? (5 points)

Iteru [2.4K]

The possible scenario for singing traits in female birds will be about 26% in Generation 4 species

Explanation:

Singing trait have been common among both male and female birds and it is an ancestral traits. However, singing has been more sex-specific with male birds. Reasons for which birds generally sing are:

To attract the mates
While making nests and laying eggs
For the young birds to recognize their parents

However, various studies prove that the singing trait in female birds is reducing with increase in non-singing female birds over the years due to evolutionary course.

Science when birds remain airborne and moving without flapping their wings, on what are they gliding?

Citrus2011 [14]

Soaring is a science when birds remain airborne and moving without flapping their wings. They are maintaining thrust and gliding downward but staying aloft

<h3 /><h3>Further explanation</h3>

Soaring birds is where the birds can maintain flight without wing flapping, because they using rising air currents. Many gliding birds are able to lock their extended wings by means of a specialized tendon. Some land birds such as vultures and certain hawks, sustain flight for long periods without flapping their wings.

For example soaring California Condor spreads its primary feathers so that each acts as a small, high-aspect-ratio wing. This reduces turbulence at the wingtips and helping the condor to stay aloft circling slowly in thermals.

Vultures have a low aspect ratio (ratio of length to width of the wing) which generally produce a lot of drag. Vultures overcome the problem of by flying with their primary feathers extended, creating slots between them. Each primary serves as an individual high-aspect-ratio wing. This high-aspect-ratio reducing wingtip turbulence and lowering the stalling speed of the wings. This helps vultures to circle in thermals, maintaining thrust by gliding downward, but staying aloft by sinking at a rate slower than the hot air rising.
