B.
Deforestation affects ecosystems on land. there are no forests underwater
In artificial selection, nature provided the variation, and human selected those variations that they found useful
Solution A have more hydrogen ions as pH level 2 indicates that it is highly acidic which means presence of H+ ions. On the other side sol B with ph10 has more OH- ions in it making it base in nature.
Answer:
1. How did the tidal wave affect the predicted frequencies of the alleles in the population?
No changes
2. What is the frequency of the recessive allele?
q= 0.6
Explanation:
If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.
If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:
q^2 = 36/100
q= √36/100= 6/10= 0.6
