Answer:
These are the basic steps of urine formation.
Explanation:
The first step comprises creating a filtrate in the glomerulus.
During the second stage, the filtrate flows through the tubules, and useful substances are reabsorbed.
Waste products will then be secreted by the tubules.
Whereas, the final stage is the conservation of water that occurs in the renal tubule.
There are four major stages in the formation of urine.
The tadpole would die out. Which would cause the sudden decrease I duck and frog.
It is the circulatory system and respiratory system.
It was the trip that Charles Darwin went on in attempt to find the answer of how animals got on earth in the first place and how they changed over time. This later on helped him discover evolution and natural selection. The most significant find on this voyage was that he found that different types of finches evolved to the food around them. Smaller beaks meant the finch ate more small nutrients but larger beaks meant the finch ate more harder prey such as fish and worms.
Answer:
sympathetic stimulation
Explanation:
Under stress or emergency conditions, the preganglionic neurons of the sympathetic division release acetylcholine. Acetylcholine stimulates secretion and release of epinephrine and norepinephrine from the adrenal medulla. These hormones enhance the effects of the sympathetic division of the autonomic nervous system (ANS) during stress. Epinephrine and norepinephrine augment the fight-or-flight response as they increase the heart rate and force of contraction, the output of the heart, and blood pressure. They also increase blood supply to the heart, liver, and adipose tissue. The airways to lungs become dilated and there are increase blood levels of glucose and fatty acids.
