Answer:cacti

Explanation:

In an ecosystem,the ultimate source of energy is the sun. Plants take up this energy from the sun to produce food. Animals eats up plants and when they die ,they decompose. This continuing process leads to the transfer of energy from one trophic level to another in the ecosystem.

Plants ,algae and some bacteria are the primary producers in the ecosystem.they are able to make their own food and support the entire living system. They extract inorganic nutrients and energy from the environment, in order to make their food. Animals(herbivores) eats up the plants and other animals(carnivores) eat up such animals. This situation sets up a chain of flow of energy from the producer to the consumer and back to the environment.

A particular recessive genetic disorder is fatal before birth, so there are no homozygous recessive individuals. In a particular
Ksenya-84 [330]

Answer:

  • the allelic frequency for p is 0.967
  • the allelic frequency for q is 0.033

Explanation:

According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the alleles. The genotypic frequencies after one generation are p² (Homozygous for allele p), 2pq (Heterozygous), q² (Homozygous for the allele q). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.

In the exposed example,

  • A recessive genetic disorder is fatal before birth, so there are no homozygous recessive individuals
  • In a particular population, one in 15 individuals is a carrier for this disorder.

What are the allele frequencies of the dominant (p) and recessive (q) alleles in this population?

If 1 of 15 individuals are carriers for this disorder, this means that 1/15 are heterozygous, 2pq. So, 2pq = 1/15 = 0.066

Now we must calculate the allelic frequencies.

We know that 1 in 15 individuals are heterozygous, and we also know that there are no recessive homozygous, q², because they can not survive, so of the 15 individuals only one is heterozygous and the rest 14 individuals must be dominant homozygous, p².

The dominant homozygous genotypic frequency is

p²= 14/15 = 0.933

And by clearing the next equation we can get the allelic frequency for p

p²= 0.933

p = √0.933

p = 0.967

So now we know that the allelic frequency for p is 0.967  

This means that the allelic frequency for q or p is 0.033, which we deduce by clearing the equation p + q = 1

                          0.967 + q = 1

                         q = 1 - 0.967

                          q = 0.033

  • the allelic frequency for p is 0.967
  • the allelic frequency for q is 0.033

Which characteristic best distinguishes runoff and infiltration?
Sever21 [200]

The right option is; d. Runoff describes water movement and infiltration describes water storage.

Runoff is the portion of precipitation, irrigation or snow melt that flows over land as surface water instead of infiltrating or evaporating. Factors that influence runoff are permeability, amount of rainfall, slope and vegetation.  

Infiltration is the process by which water or precipitation on the ground surface moves into the soil. Factors that determine the rate of infiltration include; soil type, topography of the land, amount of precipitation, vegetation, and pre-saturation levels.
