Genes contain instructions for assembling Question 56 options: a. purines. b. nucleosomes. c. proteins. d. pyrimidines.
sergejj [24]

Answer:

c. Proteins

Explanation:

A stretch of DNA that code for specific proteins is said to be a gene. A gene is transcribed into mRNA. The mRNA has a nucleotide sequence complementary to the corresponding gene. The nucleotide sequence of mRNA is read in the form of genetic codes during the process of protein synthesis to specify the amino acid sequence of proteins. Therefore, genes carry the genetic information for the assembly of proteins and the processes of transcription and translation deliver the stored genetic information.

ella [17]

Enzymes come from the pancreas.

What are Enzymes?

Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

The small intestine, not the stomach, is where carbohydrates are chemically broken down. The chemical breakdown of digestible carbohydrates is completed by disaccharidases and pancreatic amylase. The circulation carries the monosaccharides to the liver after absorption.

Water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a(n) __________ in tubular fluid v
notsponge [240]

Water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.

<h3>What do you mean by Proximal tubule?</h3>

A Proximal tubule may be defined as the portion of the nephron that lies in between Bowman's capsule and the loop of Henle.

The major function of the proximal tubule is to reabsorption of sugar, sodium, chloride ions, and water from the glomerular filtrate. It decreases the volume of tubular fluid.

Therefore, water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.
