Answer:
air
Explanation:
The water molecules are being added to the oxygen and hydrogen in the air, which makes it heavier
The answer is 149 to 159 pounds.
A recommended pregnancy weight gain for women who are at their appropriate weights is of 25 to 35 pounds.
Nancy weighs 124 pounds and is at an appropriate weight for her height, So Nancy should gain 149 to 159 pounds at the end of her pregnancy.
Answer:
Explanation:
Using renewable energy will always be better than fossil fuels.
This is because fossil fuels need a very long time to renew themselves. And we will run out of them long before they can renew themselves. Besides this, there is a more concerning and very alarming issue with using fossil fuels instead of other energy sources. Global warming and environmental destruction is a very big problem for us in the 21st century. The air is more and more polluted. Temperatures are rising and oceans are rising with them. We will lose the ability to grow food and raise animals in the future if we continue like this.
Answer:
allelic frequency a = 30%
allelic frequency A = 70%
Explanation:
You are studying a population of sparrows in which the phenotype is determined by a single locus. Only two alleles for this locus are known for this population, which are distinguished by the codes 'A' and 'a'. The distribution of phenotypes in the population indicates that 49% of the population is homozygous 'AA', 42% is heterozygous and 9% 'aa' homozygous. How is the allele frequency for 'A' and 'a' determined based on these observations?
According to the case, the allelic frequency for A and a will be searched with the data:
homozygotes AA = 49%
heterozygotes Aa = 42%
homozygous aa = 9%
Frequency of homozygotes 'aa'
(q 2) = 9/100 = 0.09
we can obtain the allelic frequency of a through the following formula:
a (q) = √0.09
The result will be
= 0.3
we change to percentage
= 30%
we have the following formula
p + q = 1
to find the allele frequency A, represented by p
p = 1 - 0.3
we get the following result
p = 0.7
we change to percentage
= 70%
