zzz [600]3 years ago

The answer is alveoli.

The bronchi conduct air to the lungs. They branch into secondary bronchi, which further branch into tertiary bronchi. They divide into small bronchioles. Bronchioles divide into terminal bronchioles, they into respiratory bronchioles, and later into alveoli. The alveoli are places where gas exchange occurs.

Stretch reflexes: Multiple Choice
sammy [17]

Answer:

aid in maintaining proper posture.

Explanation:

Stretch reflexes are the monosynaptic reflexes. These reflexes are produced by tapping on tendons attached to muscles at the elbow, wrist, knee, and ankle joints. One of the functions of the stretch reflex is to help maintain posture. For example, when a standing person begins to lean forward, stretching of calf muscles initiate the stretch reflexes. These reflexes cause the calf muscles to contract to restore the body’s upright posture. Similarly, stretch reflexes also occur in the muscles of the shin when a standing person begins to lean backward.

The atmosphere is 80% nitrogen: why do you think plants and animals can't use nitrogen as it is found in the atmosphere?
Setler [38]

Answer: Atmospheric Nitrogen is unreactive

Explanation:

The atmosphere is made up of about 80% Nitrogen, 16% oxygen, about 4% carbon dioxide, rare gases etc.

However, the 80% Nitrogen is highly unreactive, and needs to be trapped by competent micro organisms known as nitrogen-fixing bacteria in the root nodules of legumes.

Then, it is converted to several forms like nitrites, nitrates (easily absorbed by plants), ammonia and finally escape to the atmosphere again.

This brief illustration explains the NITROGEN CYCLE, and it is the only means by which plants and animals can use the highly unreactive nitrogen
