Explain one way that land use by humans affects<br> nutrient cycles.
Nataly_w [17]

Answer:

We (humans) remove nutrients from the land and discharge them into aquatic environments. On one hand, this leads to soil depletion on the land, and on the other hand, an over abundance of the nutrients and pollution of water sources.

Define hypogeal germination and Epigeal germination​

Explanation:

Hypogeal germination is when the plant is germinated under the ground. An example of this would be the pea plant.

epigeal germination is the opposite of that. Germination takes place above the ground. normal bean plants have epigeal germination

- 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.
