White feathers in canaries are dominant to yellow feathers. A heterozygous canary is crossed with a homozygous recessive canary. What ratio of the offspring will be homozygous recessive? 1 : 4 What percent of the offspring will be heterozygous? 25 %

Answer:

1. RNA polymerase binds to the promoter.

2. DNA strands are unwound and separated

3. The complementary RNA nucleotides are added.

Take a look at the attached picture. First, the RNA polymerase must bind to the promoter region to initiate the whole process. DNA must be unwound by DNA helicase, then it will make the RNA transcript, which consists of adding the complementary RNA nucleotides to the DNA strand. Then the transcript leaves the nucleus and begins translation.

DNA strands are unwound and separated, RNA polymerase binds to the promoter, and the complementary RNA nucleotides are added. These are the steps of transcription in order.

Transcription is the process by which RNA molecules are synthesized from DNA templates. The first step in transcription is the unwinding and separation of the DNA double helix by an enzyme called RNA polymerase.

The enzyme binds to the DNA template strand separating the two strands and DNA template strand is further used for RNA synthesis, while the other strand is the non-template or coding strand. RNA polymerase then binds to the promoter region of the DNA template strand which is located at the start site of transcription.

After the binding, a complementary RNA starts synthesizing using the DNA template strand by adding complementary RNA nucleotides. As the RNA polymerase moves along the DNA template strand, RNA molecule starts growing which is complementary to the DNA template strand. This step is followed by elongation and termination of growing RNA molecule.

Therefore, transcription steps include DNA strands are unwound and separated, RNA polymerase binds to the promoter, and the complementary RNA nucleotides are added.

....

Explanation:

In the Hardy-Weinberg equation shown below, p is the frequency of the

dominant allele, and is the recessive allele. p² in the equation represents the frequency of the homozygous dominant genotype.

Usually, a dominant allele codes for a protein that functions. Because only one copy of the allele is required to produce enough enzyme to fully provide a cell with a specific product, the allele is dominant.

An organism's phenotype, or observable traits, are derived from its genotype, or the chemical makeup of its DNA. All the nucleic acids in a DNA molecule that code for a specific trait are collectively known as a genotype.

Answer:

density independent

Explanation:

In Ecology, a limiting factor refers to an environmental condition that hinders the growth and distribution of organisms in an ECOSYSTEM. A limiting factor hinders or hampers the productivity of an organism in its habitat.

There are two major types of limiting factors that affect organisms in their ecosystem viz: density dependent and density independent limiting factors. Density independent factor limits the size of a population independently of how dense the ecosystem's population is. This means that density independent factor affects a population irrespective of its size. Example of density independent factor are natural disasters e.g earthquake, hurricane, forest fire as mentioned in the question.

In this question, both populations of trees and birds are affected irrespective of the size of the ecosystem's population.

Answer:

Albumin is a protein that attracts water in the compartment where it is found, that is why when circulating within the blood vessels the blood volume is maintained by this protein, so that the liquid or fluid that makes up the blood volume is retained within the capillaries due to hydrostatic forces and because the albumin protein is hydrophilic.

The albumin is decreasing, that is, in deficit or hypoalbulinemia, less water reaches the blood compartment, therefore the blood pressure or pressure will drop, the blood volume will decrease but not due to loss of it as in hemorrhages, but due to diffusion to other compartments. VASCULAR through the processes of OSMOSIS, in simple words, when this protein descends, water filters from the blood vessels to extravascular compartments, this phenomenon clinically manifests itself as EDEMA.

Explanation:

Hypoalbulinemia also occurs in severe nutritional disorders where ovalbumine is not consumed through the egg, since the person's diet is severely lacking, generating massive edema in the abdominal area or abdominal distension.

The effect that the plasma liquid has in spreading to extravascular spaces is called OSMOSIS, which draws water from the external environment by the oncotic pressure generated by other proteins.

The oncotic pressure is the pressure that is generated when the water diffuses from one compartment to another by attraction of a protein, it happens both with albumin and with other proteins of the organism that are characterized by being hydrophilic or attracting water.

Hypoalbulinemia destroys severe cardiac symptoms due to the high demand that an increase in edema and difficulty of venous return entail along with the fall in blood pressure.

Answer:

It helps to control what substances move in and out of the cell.

Explanation:

Phospholipid bilayers are critical components of cell membranes. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell. However, an important function of the cell membrane is to allow selective passage of certain substances into and out of cells. This is accomplished by the embedding of various protein molecules in and through the lipid bilayer. These proteins form channels through which certain specific ions and molecules are able to move. Many membrane proteins also contain attached carbohydrates on the outside of the lipid bilayer, allowing it to form hydrogen bonds with water.

Introduction of non-native species

Explanation:

That would most likely lead to reduced bird populations is O C. Introduction of non-native species.Non-native predators may also prey on native birds and their eggs, leading to population declines.

Non-native species, also known as alien, exotic, or introduced species, are organisms that have been introduced into a geographic area where they did not occur naturally, either intentionally or unintentionally, by humans.

C. Introduction of non-native species is most likely to lead to reduced bird populations.

Non-native species may compete with native species for resources such as food, nesting sites, and breeding territories, and may also introduce new diseases and parasites that the native species may not be able to cope with.
