Answer:
B. reduce greenhouse gas emissions
Explanation:
The hydroelectric energy has its pros and cons as most of the energy production facilities do. One of the biggest advantages of the production of this type of energy is that it almost doesn't emit any greenhouse gases into the atmosphere. Considering the problem that the world is facing because of it, especially the climate changes and rising sea levels because of that, this is seen as a very big plus for any type of energy production. This has resulted in the building of more and more dams that produce hydroelectric energy, some of which have been made very large and very large energy production.
Answer:
Divergence
Explanation:
This happens because of the different genetic makeup or genotype of different individuals. The divergence mechanism occurs because of divergent evolution where in some cases random chances occurs and neurons became a source of stimulus for one but not other and vice versa.
Answer: If this population were in equilibrium and if the sickle-cell allele is recessive, the proportion of the population susceptible to sickle-cell anemia under typical conditions should be 0.20
Explanation: Hardy-Weinberg law provides an equation to relate genotype frequencies and allele frequencies in a randomly mating population. The equation is;
p² + 2pq + q² = 1
For 2 alleles such as A and a, where
p² = homozygous dominant
q² = homozygous recessive and
2pq = heterozygous
From the question, it is said that the sickle-cell allele (SS) constitutes 20% (that is, 20/100) of the hemoglobin alleles in the human gene pool and it is also said to be the homozygous recessive allele.
Therefore, q² = 20/100 = 0.20
