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.

The anwser should be B. Nonrenewable resources generally have a higher impact on the environmental than renewable resources.

- For plants and other organisms to develop differences among their respective species the alleles of their genes must contain
andre [41]

Explanation:

Mutations increase variation within a population.

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Further Explanation:

During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

What components of the introns of nuclear genes that encode proteins in higher eukaryotes are conserved and required for the cor
leonid [27]

Answer:

The introns of protein-encoding nuclear genes of higher eukaryotes almost invariably begin (5') with GT and end (3') with AG. In addition, the 3'subterminal A in the “TACTAAC box” is completely conserved; this A is involved in bond formation during intron excision.

What are genes, where are they found, and what do they do?
Gala2k [10]
Genes are DNA or RNA, they act as instructions to make molecules called proteins! They are found in chromosomes and there main objective is to carry out information that determines your characteristic traits that are inherited from your parents!

Hope that helps :))
