Answer:

Rivers often start from the mountain streams and contain high amounts of oxygen. Rivers and streams grow larger as these waters merge. Rivers pick up sediments from the land as they flow. Lakes support many varieties of organisms, including plants in shallow, open water and wetlands. In shallow water near shore, plankton is covered in water all or some of the time and are found along the edge of lakes and the floodplains of rivers. A deer is nibbling moss on rocks beside a river. Rivers are a major source of water for a variety of animals and plants.

Keywords

  • Mountain streams
  • Oxygen
  • Merge
  • Sediments
  • Plants
  • Wetlands
  • Plankton

Explanation:

Freshwater ecosystems are of great importance for the diversity of plants and animals; they are also of the utmost importance for people as they are used in various ways. There are differences between freshwater ecosystems and marine ecosystems; the latter cantains a large number of salts, while the freshwater ecosystem does not provide.

Freshwater ecosystems are made up of rivers, lakes, streams, among others.

The letter X in the diagram below represents what enzyme used in the process shown?
Anvisha [2.4K]

<u>Answer</u>: Option D. RNA polymerase.

<u>Explanation</u>:

  • Transcription is the process which is used to produce RNA from a DNA template.
  • The enzyme involved in the process of transcription is <em>RNA</em> <em>polymerase</em> which is responsible for separating the DNA strands and making an RNA which is complementary to the DNA.
  • RNA polymerase joins the nucleotides in the newly formed RNA strands by utilizing the energy released from the cleavage of the additional phosphate bonds that are removed by it.
  • The RNA polymerase dissociates from the DNA only after the process of transcription is complete.

The genes R, E and D are independently assorting and control production of red pigment as follows (recessive alleles are not fun
Alona [7]

Answer:

1/8

Explanation:

An individual must have all three dominant alleles to be red, in homozygosis or heterozygosis (R_E_D_).

<u>The parental cross was:</u>

RREEDD x rreedd

F1: RrEeDd

<u>The test cross</u> is between the RrEeDd indiviudals and homozygous recessive rreedd.

The genes assort independently, so we can use Mendel's law of segregation to predict separately for each gene the proportion of the offspring that will have the dominant alleles.

<h3><u>Rr x rr</u></h3>

1/2 Rr

1/2 rr

<h3><u>Ee x ee</u></h3>

1/2 Ee

1/2 ee

<h3><u>Dd x dd</u></h3>

1/2 Dd

1/2 dd

Genes are independent, so the probability of having a R_E_D_ offpsring is calculated by multiplying the individual probabilities of having a dominant allele for each gene:

1/2 (Rr) × 1/2 (Ee) × 1/2 (Dd)= 1/8

mina [271]

Answer:

Determine the proportion of offspring phenotypes that would result when two merle dogs mate, if one dog is true-breeding for the long-coat trait and the other dog is true-breeding for the short-coat trait.

LL x ll= Ll, Ll, Ll and Ll

The phenotype of the mating between two mertie dogs with true long-coat trait and true short-coat trait is heterozygous long-coat dogs will be produced all through
