Answer:
A. The blood goes back to the heart to get oxygen.
Answer:
B. The allele frequency of T is 0.84, and the allele frequency of t is 0.16.
Explanation:
The Hardy-Weinberg equation is:
p2 + 2pq + q2 = 1
Where:
p = the frequency of the dominant allele
q = the frequency of the recessive allele
1 = the total number of alleles
Given that 16 individuals out of 100 are unable to taste PTC, we can calculate that the frequency of the recessive allele, q, is 0.16. We can then use the Hardy-Weinberg equation to solve for the frequency of the dominant allele, p:
p2 + 2pq + q2 = 1
p2 + 2p(0.16) + (0.16)2 = 1
p2 + 0.32p + 0.0256 = 1
p2 + 0.32p - 0.9144 = 0
(p + 0.32)(p - 2.84) = 0
p = -0.32 or p = 2.84
Since the allele frequencies must add up to 1, we know that p cannot equal -0.32. This leaves us with p = 2.84. Therefore, the allele frequency of the dominant allele is 2.84, and the allele frequency of the recessive allele is 0.16.
Answer: Cell death abnormality gene 9 (CED-9) is found in Caenorhabditis elegans inhibits/represses programmed cell death (apoptosis) also known as apoptosis regulatorCED-9
Explanation:
Well with the ph above 7 that means the water is more of a base due to the salt within the water. the decrease in the ph is due to gloabal warming and the melting of ice which is somewhat diluting the water more. the wildlife within the ocean has been there since you or i so some creatures have developed a very specific habbitat and less salt withing the water could have effects on them. one such instace is if the organism needs a lot of salt. a decrease in salt would mean that their cells would bloat with water until they explode. this would obviously hurt the species as a whole and in turn effect the whole food chain.
