<u>Answer: </u>One isotope has a percentage abundance of 75.75 % and the percentage abundance of another isotope is 24.24%.
<u>Explanation:</u>
We are given the two stable isotopes of chlorine with their respective masses. The average atomic mass of chlorine is also given.
Average atomic mass of chlorine = 35.45 amu.
Let us assume the fractional abundance of one isotope be 'x' and the fractional abundance for another isotope will be (1 - x) because the total fractional abundance is always equal to 1.
Fractional abundance = x
Mass = 34.97 amu
Fractional abundance = 1 - x
Mass = 36.95 amu
The formula for the calculation of average atomic mass is given by:
Putting values in above equation, we get:
Converting these two fractional abundances into percentage abundances by multiplying it with 100.
Hence, one isotope has a percentage abundance of 75.75 % and the percentage abundance of another isotope is 24.24%.
Answer;
-Decrease
if the producer population decreased then the size of the herbivore population will consequently decrease.
Explanation;
Producers
are organisms that make make their own food through a process known as photosynthesis, e.g. plants such as grasses. Herbivores are the organisms which feed on producers. Examples of herbivores are rabbits, giraffes etc.
-An increase in producer population means that there will be a a corresponding increase in the population of herbivores while a decrease in the size of producers will cause a decrease in the population of herbivores.
When two object occupy the same space or have the same volume, but one of them is heavier than the other. This means that the heavier object is having a higher mass which results in a higher density than the other (lighter) object.
Note that density is calculated using the following rule:
density = mass / volume
