Answer:

A

Explanation:

The sun is what drives most processes, the sun gives energy to the plants which help them grow resulting in creatures consuming the plants.  The sun is the major source so remeber that! :D                

I am sure this is the answer so I hope this helps you!

Which enzyme(s) involved in fatty acid synthesis utilize ATP? Select all that apply.
GREYUIT [131]

Answer:

a. Acetyl CoA carboxylase  

Explanation:

Much of the fatty acids used by the body is supplied by the diet, excessive amounts of carbohydrates and protein obtained from the diet can be converted to fatty acids and stored as triglycerides. Fatty acid synthesis occurs mainly in the liver and mammary glands, and to a lesser extent in adipose tissue and kidney, the process incorporates acetyl CoA carbons into the forming fatty acid chain using ATP and NADPH.

The acetyl portion of acetyl CoA is transported to cytosol as citrate, produced by condensation of oxaloacetate and acetyl CoA, the first reaction of the citric acid cycle, this occurs when the concentration of mitochondrial citrate is high, observed when there is a high concentration of ATP and isocitrate dehydrogenase is inhibited.  The increase of citrate and ATP favors the synthesis of fatty acids, since this pathway needs both. Acetyl CoA should be converted to malonyl CoA. Carboxylation is catalyzed by acetyl CoA carboxylase and requires ATP, this reaction is the regulated step in fatty acid synthesis: it is inactivated by products, malonyl CoA and palmitoyl CoA, and activated by citrate, another regulatory mechanism is reversible phosphorylation of enzyme, which makes it inactive due to the presence of adrenaline / glucagon

The nurse is instructing a patient with recurrent hyperkalemia about following a potassium-restricted diet. Which of the followi
blondinia [14]

Answer:

"I will not salt my food, instead I'll use salt substitute."

Explanation:

Hyperkalemia may be defined as the medical condition in which the individual has high level of potassium in the body. This hyperkalemia can cause different diseases like cardiac arrest and can also cause death.

The hyperkalemia must be treated on time. The individual must be on low potassium diet. Avoid medicines that can increase the potassium levels and the administration of the sodium bicarbonates. The salt that has low potassium and high sodium concentration must be included in the diet.

Thus, the correct answer is option (b).

In 1-2 sentences, describe what a sequence-tagged site (STS) is and how STSs are used in genome sequencing.
Ede4ka [16]

Answer:

STS are short stretches of DNA used for producing genomic map

Explanation:

Sequence tagged sites (STS) are primers that possess some form of sequence knowledge and are used to produce genetic maps through standard mapping procedure. STS primers are short replica or stretch of DNA which is detected by using PCR array.

These STS primers are unique and sequence specific and thus are responsible for detecting variations in genomic DNA and can also distinguish between homozygotes and heterozygotes.

Match each definition to the appropriate term. locus
liraira [26]
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.


ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA. 

iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.

iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.
