Answer:
I'm almost positive it's answer c. :)
Answer and explanation:
Epinephrine and norepinephrine are two hormones that are released from the adrenal medulla when the body is under stress (like during exercise, for example) as a part of the sympathetic response.
These hormones have many functions and they all work together to prepare the individual for a fight or flight response -<em> like increasing heart rate and producing bronchodilatation</em>. One of these functions is the rise of glucose levels in blood which is important for this substance to reach several tissues, like the skeletal muscle. The skeletal muscle will make use of this glucose to produce ATP and generate the required energy for muscle contraction through a process called glycolysis, which is key for the fight or flight response mentioned above.
When we exercise, glucose levels rise thanks to these hormones so the skeletal muscle can have enough energy to contract and move as we want. If the exercise is too intense or prolongued, glucose levels will drop and other fuels will be needed to sustain this activity, like stored glycogen and fat.
Answer:
urethral
Explanation:
The urethral opening is called the meatus and lies on the tip of the glans penis. It serves as a passage both for urine and semen.
Answer:
Primary producers (autotroph organism), primary consumers (herbivores), secondary consumers (carnivores), decomposers
Explanation:
The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. The next links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
When one of the links disappears, it affects the superior links as they will not have their food source. The immediately anterior link will be beneficiated, as it will not be eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link.
Answer:
(a) Manual Dexterity and large brain size
Explanation:
In primates there cerebrum is expanded. The area of the brain that correlate with eye Hans coordination and stereoscopic vision are particularly large just like in humans
