<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%
The correct answer is d. spinal cord.
Spinal cord is a bundle of neurons which starts from the brain and runs down the entire length of the back of the body. The spinal cord acts as a main means to transmit the messages between the brain and the body.
Sensory or efferent neurons carry the information from the perimeter of the body and pass to the central nervous system whereas the motor or efferent neurons act as a communication channel and carry the information from the nervous system to various glands and muscles.

Male animal aggression during mating season. The evolutionary purpose of most species is to repopulate and keep the species alive long enough to become the highest being it can evolve into (We humans have done the best at this so far). So, every male in a species gets aggressive during mating season because the stronger ones are most likely to have healthy offspring. So, when animals fight they are fighting to keep their species alive. If you think about it who wouldn't want to be responsible for the evolutionary breakthrough that kept a species alive over thousands of years? hope this helped.
Answer:
While looking for food and places to sleep, migrant birds might have more trouble
identifying windows and fly into them more often . However, it could also be that
there are simply more window collisions in the fall because there are more birds in
the area when migrant and resident birds co-occur in urban areas.
