You have a column made of nickel-agarose matrix. your protein must have ________ to use this column for affinity chromatography.

1 answer:

3 0

<span>Negatively charged R-groups in the primary structure. This is because nickel acts as a cation, therefore you would be attracting anions, in this case it would be on the proteins that would be binding to the column. Once they bind to the matrix a was buffer of high salts can elute the proteins.</span>

When Mendel crossed a plant homozygous for round seeds to another plant homozygous for wrinkled seeds, he found that all the pro

deff fn [24]

Answer:

a. The allele for round seeds is dominant to the allele for wrinkled seeds.

Explanation:

Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.

A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".

Suppose that an adult black bear adds 50 pounds of fat in order to survive while hibernating through the winter. how much glycog

NemiM [27]

Answer: The correct answer would be 112.5 pounds

Explanation:

Let us first covert the pound into grams. We know that 1 pound is equal to 453.59 grams.

Thus, 50 pound of fat = 50 x 453.59 = 22,679.5 grams.

We know that, 1 gram of fat releases 9 Kcal of energy. Thus, total energy produced by 22679.5 grams = 9 x 22679.5 = 204,115.5 Kcal

Glycogen is carbohydrate thus, it will produce 4 Kcal of energy per gram.

Thus, 4 x C = 204,115.5 (where C is the grams of glycogen)

⇒ C = $\frac{204115.5}{4}$

⇒ C = 51,028.875 grams

Using 1 pound = 453.59 grams, we con convert 51,028.875 grams into pounds:

453.59 = 1

1 = $\frac{1}{453.59}$

51,028.875 = $\frac{1}{453.59} x 51028.875$

= 112.5 pounds

Thus, 112.5 pound of glycogen would be needed to produce the same amount of energy as produced by 50 pounds of fat.

On the lines provided, enter the name of the target organ(s) affected by the pituitary hormone indicated. Hypothalamic nerve cal

Dennis_Churaev [7]

Produced by the anterior pituitary. It's regarded as a tropical hormone. Target cells are impacted by tropical hormones indirectly after being stimulated.

<h3>The anterior pituitary gland affects which organs?</h3>

The following organs, glands, and bodily tissues are affected by and interact with the anterior pituitary hormones: organs, muscles, and bones the growth hormone (GH). Adrenocorticotropic hormone: Adrenal gland (ACTH). thyroid hormone, which stimulates the thyroid gland (TSH).

<h3>What are the anterior pituitary gland's seven hormones?</h3>

Frontal pituitary

hormone adrenocorticotrophic (ACTH)

hormone that stimulates the thyroid (TSH)

Luteinizing agent (LH)

hormone that stimulates ovulation (FSH)

Prolactin (PRL) (PRL)

hormonal growth (GH)

MSH, or melanocytic-stimulating hormone

Because it releases hormones that regulate the thyroid, adrenal glands, ovaries, and testes, the pituitary gland is frequently referred to as the "master gland."

Which statement correctly describes amphipathic (or amphiphilic) helices and sheets?Helices are typically hydrophilic on one sur

Sloan [31]

Answer:

The correct answer is the last statement.

Explanation:

Amphipathic refers to a substance that comprises both hydrophobic and hydrophilic surfaces. Thus, the given first three statements are incorrect. The amphipathic helices are witnessed on the proteins surfaces in which the hydrophilic region associates with the aqueous phase and the hydrophobic regions associate with the hydrophobic component of the protein.

Both the amphipathic sheets and helices exhibit primarily the hydrophobic or hydrophilic residues on one face. Thus, the correct answer is the last statement.
