Source 2

Using any type of energy source can negatively impact the environment. Fossil fuels have the greatest and most damaging impact on the environment, but renewable energy sources can still cause a significant amount of damage—as well as cause unintended future consequences. For example, habitat loss, carbon dioxide emissions, and land destruction are just a few of the negative impacts that arise from using renewable energy sources.

   

Source 3

Renewable energies such as wind, solar, and geothermal carry the potential for environmental damage. Wind energy is a relatively clean method for producing electricity because it does not produce harmful emissions. However, this energy source requires a large amount of land. Wind turbines have been known to harm birds and bats. Solar energy also contributes to habitat loss, and making solar panels produces harmful chemicals. Geothermal energy can harm water quality. It can even cause the surface of the land to sink.

Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,
myrzilka [38]

Answer:

A) The frequency of the dominant allele, C = 0.4376

B) frequency of the heterozygous genotype, Cc = 0.2461

Explanation:

Given -

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Number of students with curly hair is 37

Thus frequency of genotype "CC"

= q^{2} = \frac{37}{117} \\= 0.3162

Thus, frequency of allele "q"

= \sqrt{0.3162} \\= 0.5623

As per Hardy Weinberg's first  equation-

p+q=1

Substituting the value of q, we get -

p+0.5623=1\\p= 0.4376

As per Hardy Weinberg's second equation -

p^2+q^2+2pq=1\\

Substituting the values of "p" and "q" we get -

0.4376^{2} + 0.3162+2pq = 1\\2pq = 0.2461\\

Hence,

A) The frequency of the dominant allele, C = 0.4376

B) frequency of the heterozygous genotype, Cc = 0.2461

Answer:

the outcome of a frame shift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of condons,or groups of three nucleotides. theses groups are called the reading frame.
