Explain how incomplete dominance differs from co-dominance

Answer:

Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring.

An example is a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring

Explanation:

good luck

You add the following components (in the correct volumes and concentrations) to a tube to perform a PCR reaction Buffer Magnesiu

uranmaximum [27]

Answer:

b. False

Explanation:

These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.

The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.

For a PCR reaction to be performed a solution with some components must be prepared. These components are:

Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
Forward and reverse primers (to customize the start of the enzyme reaction)
DNA polymerase (Enzyme required for replication of desired DNA region.)
DNA Template (the DNA to be copied)
PCR-grade water
Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).

slava [35]

Answer;

-Reproduction;

Explanation;

-Mitosis is a shape of cell division that outcomes in two daughter cells which might be genetically identical to every other and to the unique cell.In unicellular organisms together with micro organism, mitosis is a kind of asexual duplicate, making equal copies of a unmarried mobile.

- Single-celled or unicellular organisms use cell division as their method of reproduction. Mitosis is a type of asexual reproduction, making identical copies of a single cell. Cells make identical copies of themselves through mitosis.

Why did coal never form in Australia?

Archy [21]

C. Australia was covered in ice during a key geologic period.

at the time of coal forming, Australia was closest to the south pole, so it was too cold.

inn [45]

Question: Based on the model presented, which of the following statements expresses the proper relationship between osmolarity, ADH release, and urine production?

(A) As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.

(B) As tissue osmolarity rises, less ADH is released, causing less water to be excreted as urine.

(D) As tissue osmolarity rises, less ADH is released, causing more water to be excreted as urine.

Answer:

As tissue osmolarity rises, more ADH is released, causing less water to be excreted as urine.

Explanation:

ADH is the hormone that triggers the formation of concentrated urine by stimulating the absorption of water from the filtrate in the kidneys. As the solute concentration (osmolarity) in the blood raises, the more of the ADH is released into the blood. ADH triggers reabsorption of water in collecting duct and distal tubules and thereby, reduces the water loss in urine. Increased reabsorption of water restores the osmolarity, blood volume, and blood pressure.
