Which of the following is NOT a feature of cardiac muscle fibers?

Biology
1 answer:
Andreyy893 years ago
8 0

Answer:

(1)They are usually multi-nucleated.

Explanation:

Cardiac muscles are one of the three muscles found in the human body (the other two being skeletal and smooth muscles). It is the only type of muscle found in the heart. Cardiac muscle cells have a single nucleus unlike the skeletal muscle cells.

They possess many large mitochondria in their cell, which enable them actively carry out the process of aerobic respiration. The cardiac muscles contains an enormous amount of myoglobin pigment, which enable them store and transport oxygen. Due to the high glucose in its cell, excess glucose is readily stored as Glycogen, making it rich in glucose.

Based on the explanation, being MULTI-NUCLEATED is not a feature of cardiac muscle fibers.

Based on the information provided, what do you think the most ideal parameters would be for optimal glucose production?
Marysya12 [62]

The most ideal parameters for optimal glucose production are insulin sensitivity SI, glucose effectiveness SG, insulin action p2 and the volume of distribution of glucose V.

<h3>What is used for glucose production?</h3>

Insulin, glucagon, and hepatocyte-derived factors are used in these activities. Gut: Hormones are released in the gut in response to nutrition intake. These hormones affect hunger, stomach emptying, glucose production, and glucose elimination.

After eating, the beta cells release insulin into the bloodstream as your blood glucose levels rise. In order for glucose to enter muscle, fat, and liver cells, insulin works as a key to unlocking those cells. The majority of the cells in your body use glucose, lipids, and amino acids (the components of protein) as fuel.

By converting glycogen into glucose, a process known as glycogenolysis, the liver produces sugar or glucose. Additionally, the liver may produce the sugar or glucose that is required by harvesting amino acids, waste, and fat.

You have mated a phenotypically wild-type female of the genotype Xy+w+Xyw to a male with the genotype XywY. You counted 2205 tot
Vinil7 [7]

Answer:

1.31 cM

Explanation:

Total offspring = 2205

Since two genes are involved, F1 progeny should have four types of combination. Out of them two are 17 and 12 which definitely means they are in lesser number. Since recombinants are always less than parental progeny in linkage, the given two types are recombinants.

Recombination frequency = (Number of recombinants / Total progeny) * 100

= [ ( 17 + 12 ) / 2205 ] * 100

= ( 29 / 2205 ) * 100

= 1.31 %

Map distance = Recombination frequency

Hence, distance between two genes = 1.31 cM
