The correct answer is the cluster sample is obtained by selecting individuals who are easily contracted rather than who voluntarily respond because cluster sampling is a way of dividing a group then the individual responsible for picking from the selected population will select people from the cluster in which is easily contacted.

Anvisha [2.4K]

If a person uses up his or her reserve supply of glycogen and still does not eat, sugar comes from the muscle.

Although only liver glycogen directly contributes to the release of glucose into circulation, maintaining a healthy blood glucose concentration is one of the glycogen's key functions. Since skeletal muscles lack glucose 6-phosphatase, they are unable to release glucose, and muscle glycogen primarily serves as a local energy source for activity rather than a source of fuel to keep blood glucose levels stable while fasting.

In fact, the breakdown of muscle glycogen into lactate allows for its delivery to the liver, where it participates in the maintenance of euglycemia through the process of gluconeogenesis (Cori cycle).

A swine producer wants to know if the average weight of his pigs is different from the breed average of 230 lb. He selects a ran
Aloiza [94]

Answer: t= -1.60

Explanation:

Let \mu be the population mean weight of pigs.

As per given , we have

H_0:\mu=230

H_0:\mu\neq230

Sample size : n= 16

Sample mean =\overline{x}=220\ lb

Sample standard deviation : s=25\ lb

<em>Since the population standard deviation is not known so the test is a</em><em> t-test.</em>

Test statistic for population mean : t=\dfrac{\overline{x}-\mu}{\dfrac{s}{\sqrt{n}}}

t=\dfrac{220-230}{\dfrac{25}{\sqrt{16}}} (Substitute all the values.)

t=\dfrac{-10}{\dfrac{25}{4}}

t=\dfrac{-40}{25}=-1.60

Hence, the value of the test statistic needed to test the null hypothesis : t= -1.60

How many capillary beds must a red blood cell pass through to move from an artery in the left arm to the left ventricle of the h
MArishka [77]

Answer:

two capillary beds

Explanation:

Capillary beds are networks of capillaries that supply blood to the organs and/or areas of the body, in which nutrients and gas exchange (i.e., O2 and CO2) between red blood cells and tissues take place. Smaller arteries (i.e., arterioles) diverge into capillary beds composed of 10 to 100 capillaries, the smallest blood vessels in the body that connect the arterioles and the venules. Red blood cells usually flow into a capillary bed from a metarteriole (i.e., a microvessel that connects arterioles and capillaries). Red blood cells sometimes pass through two capillary beds before reaching the heart. The left heart ventricle is a muscle required for pumping red O2-rich blood out through the aortic valve into the aorta, whereas arteries are large blood vessels that branch into arterioles in order to carry blood to the capillary beds.
