Some species we see in Alaska and nowhere else in the Wolrd are:
Bats
Shrews
Bears
Seals
White Wolfs
Sea lions
Racoons
Walrus.
Bears, Seals, White Wolfs and Sea lions survive the cold weather much more than those other animals.
Answer:
Negative feedback mechanism
Explanation:
Negative feedback mechanism occurs when the product or the output of a process inhibits the same process. When blood glucose level rises, body receptors stimulate beta cells in pancreas to release insulin. Insulin leads to uptake of glucose by cells, lowering the blood sugar levels. The lowered blood sugar level is again sensed by the receptors and they inhibit the secretion of insulin. Hence, insulin inhibits its own secretion by removing glucose from blood which makes it a negative feedback mechanism.
To establish causation sociology, there are three key factors namely correlation, time order and ruling out alternative explanations. correlation gives the difference between the alternatives to be considered, time order gives the occurrence of events chronologically, finally, the ruling out alternative explanation gives one the chance to get the best alternative
Answer:
As the blood pressure in each of the blood vessels is measured, it can be predicted to be lowest in the capillaries.
Explanation:
Options for this question are:
- <em>Artery.</em>
- <em>Arteriole.</em>
- <em>Capillaries.</em>
- <em>Venule.</em>
- <em>Vein.</em>
Once the blood leaves the heart, it is distributed in a network of arterial vessels -arteries and arterioles- that bridge the venules and veins through the capillaries. Blood pressure depends on the pumping strength of the heart and the force that blood produces on the vessel walls. There is a marked difference between arterial and venous pressure. Some conclusions can be drawn from this:
- <em>Blood pressure is higher the closer the vessel is to the heart.
</em>
- <em>The larger the vessel, the more blood is contained and the more blood pressure is recorded.
</em>
Based on this, it can be deduced that the blood vessels with the lowest pressure are the capillaries, with very thin walls and where gas and nutrients or metabolites enter and leave the vessel.
The question gives an answer, but does not explain why.
