<u>Question</u>:
Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?
-
years of decay
- quantity of energy
- number of stable atoms
- amount of material that has not decayed
<u>Answer</u>:
"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”
<u>Explanation</u>:
The table shown below having explains about the half life , the amount of sample in both fraction and percentage. The first column named half life elapsed tells us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.
The fraction remaining column gives the amount of sample that is left behind after the half life particular number of half life has completed. similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over 
of the sample remained. In percentage it is 6.25%
Answer:
In the explanation. :)
Explanation:
Human powered generators are the best source for the rescue team. We cannot always depend on the sun. What if the sun is not out that day? What if it's a rainy day? What if the sun is what's causing the rescue team to come out? Human powered generators are sometimes untrustworthy, but at the same time we know that at least it's a step away. We don't have to wait all-day for the sun to help out. Of course, the energy from the sun is always going to be there and won't cause anybody hurt, harm, or danger, but at the same time we can always convert to human powered generators and they'll work just as perfect.
Hope this helps, have a great day!
Answer:
regulation of the diameter of blood vessels and control of blood pressure
Explanation:
Skeletal muscles are the multinucleated muscles with striations and are attached to the bones (skeleton). The main function of skeletal muscles is to generate the voluntary movement of the body or body parts. The skeletal muscles of face, rectum, and urinary bladder generate their voluntary movement as per the will of the organism. On the other hand, blood vessels are lined with smooth muscles with spindle-shaped cells.
For example, the muscles present in the subcutaneous layer of the skin of the face are responsible for various facial expressions. Contraction of these facial muscles brings about the movement of skin of the face to generate a wide variety of emotions. Smooth muscles of blood vessels are involuntary in nature.
Vasodilation and vasoconstriction as brought about by smooth muscles of blood vessels are regulated by the autonomic nervous system. Under the conditions of lower blood pressure, contraction of smooth muscles of blood vessels restore the reduced blood pressure. On the other hand, when the blood pressure rises above the normal range, the smooth muscles of blood vessels relax to dilate them and to lower down the blood pressure.
The correct answer for this question would be option C. The environmental <span>condition that contributed to the heat wave experienced in Europe and the thousands of deaths in France is air pollution. A heat wave is when there is a prolonged period of abnormally hot weather. In this case, air pollution, having chemicals present in the air, contributed and worsen the heat wave.

The kidney filters about 200 quarts of blood to remove about 2 quarts of waste and excess water. That excess water and waste is sent to the bladder and leaves the body as urine.
