Answer:

both ions are transported actively

Explanation:

If both ions are being transported against their concentration gradients, then they are both being transported by active transport, as it requires energy.

A co-transporter moves two substances across the membrane, one passively and one actively. But in this case neither ion is moved passively, so it cannot be considered a cotransporter

Suppose a 0.1M solution of a monosaccharide contains 1000 monosaccharide
seropon [69]

0.1 M solution of a disaccharide solution will contain 2000 monosaccharide molecules.

<h3>What are monosaccharides?</h3>

Monosaccharides, also known as simple sugars are the simplest monomers of carbohydrates which may either be 3 carbon, 4 carbon, 5 carbon, 6 carbon or 7 carbo compounds.

There are two types of monosaccharides;

  • aldoses sugars, e.g. glucose, and
  • ketose sugars e.g. fructose.

When two monosaccharides are linked together by glycosidic bonds to form a single compound, the compound formed is called a disaccharide.

Considering the give question:

Suppose a 0.1M solution of a monosaccharide contains 1000 monosaccharide molecules. How many monosaccharide molecules would be in a 0.1 M solution of a disaccharide.

The number of monosaccharides molecules present in the 0.1 M solution of a disaccharide is determined as follows:

1 disaccharide molecule contains 2 monosaccharide molecules

0.1M solution of a monosaccharide contains 1000 monosaccharide molecules.

0.1 M solution of a disaccharide will contain 2 * 1000 monosaccharide molecules

0.1 M solution of a disaccharide will contain = 2000 monosaccharide molecules.

Is the following an example of a. Negative feedback loop b. Positive feedback loop Hydrochloric acid and pepsin are enzymes secr
Finger [1]

Answer:  This is a positive feedback loop.

Explanation:

The protein digestion in the body is an example of the positive feedback. The gastric secretions is stimulated chiefly by the action of three chemicals.

These chemicals are acetylcholine, histamin and gastrin. These chemicals stimulate the parietal cells to secrete HCL and intrinsic factors.

The chief cells secrete pepsinogen in response to the gastrin and ACh. As the dietary proteins are digested, it breaks down the amino acids and peptides.

This stimulates the G cells of the stomach to secrete more gastrin. This is how the positive feedback loop for the protein digestion works.

Some digestive products, such as water and electrolytes, will be absorbed by diffusion. They diffuse from an area of ___________
Montano1993 [528]

Answer: Higher concentration; Lower concentration.

Explanation: The food that we eat undergoes digestion and breaks down into smaller components.

These small components of the food needs to be absorbed first by the process of diffusion.

The water molecules along with the electrolytes are absorbed from an area of its higher concentration in the lumen is transported to area where its concentration is very low.

Hence, the correct answer is diffusion, which is responsible for the transportation of products from one place (higher concentration) to another parts (lower concentration)in the body.

When Gregor Mendel crossed a tall plant with a short plant, the F1 plants inherited.
lys-0071 [83]
<h2>Answer:</h2>

a. one allele from each parent

<h2>Explanation:</h2>

An allele in biological sciences is one of the possible forms of a gene that it can inherit. Most genes have two alleles, a dominant allele and a recessive allele. When Gregor Mendel crossed a tall plant with a short plant, the F1 plants inherited an allele for tallness from the tall parent and an allele for shortness from the short parent.
