Answer: b. causes the gastric glands to increase production of gastric juice.

Explanation:

The parasympathetic nerves are part of the autonomous nervous system. The parasympathetic predominates mainly during "passive responses" of the organism, such as satiety, rest and digestion. Its functions are: Promotes energy conservation, Reduces heart rate, Promotes glandular secretion, Protects the retina from excess light, Promotes emptying of cavities, Promotes rest and repair, Physiologically antagonizes sympathetic nervous system.

Answer:

b. causes the gastric glands to increase production of gastric juice

Explanation:

Parasympathetic stimulation is a function that is carried out by the Parasympathetic Nervous System which is a part of the Autonomic Nervous System.

Parasympathetic stimulation results in the process of digestion, production of saliva, production of urine, Production of tears, decrease in the heart rate and blood pressure.

Parasympathetic stimulation is involves in the process of digestion because after the injection of food , when the body is at rest, Parasympathetic stimulation increase the rate of the digestion process by, stimulating the gastric glands so that they can produce more gastric juice. This gastric juice contains enzymes and some other substances such as

a. Pepsin for the digestion of protein.

b. Renin

c. Hydrochloric acid (HCl) in other to deactivate any bacteria found food present in the stomach.

d. Mucus which helps to protect the lining of the digestive system.

A plant cell is placed in distilled water, as shown in the figure. There is a net uptake of water by osmosis, causing the cell t

Korvikt [17]

Answer:

The water potentials (Ψ) of the cell and its surroundings are the same.

Explanation:

When a cell is kept in hypotonic surroundings such as distilled water, the osmotic movement of water occurs towards the cell. The entry of water makes the cell swell up and it becomes turgid. Water potential is determined by solute and pressure potentials mainly. Here, the solute potential of the cell and the distilled water was different resulting in differences in their respective water potential values which in turn served as a driving force for endosmosis.

When the cell is fully turgid, the solute concentration of the cell and the surrounding distilled water become equal to each other. Under these conditions, the water potential of the cell and distilled water are the same.

Which evolutionary mechanism changes genotype frequencies but does not change allele frequencies?

Montano1993 [528]

Assortative mating is the evolutionary mechanism that changes genotype frequencies but does not change allele frequencies.

Assortative mating is the type where two individuals mate with each other on the basis of their similarities and dissimilarities. This is a different phenomenon than the random mating that occurs by chance. Assortative mating can be used to increase the number of organisms of a population containing a certain trait.

Allele is the alternative form of a gene. It arises due to mutations. A gene can have more than one types of alleles. However, usually a gene only has one allele. The alleles are found at the same location of the homologous chromosomes.

Can somebody give me the answer for these...

labwork [276]

Answer:

1. Life cycle of a cell starts from

G1 phase - S phase (synthesise phase) - G2 phase - mitosis.

2. By mitosis bcoz it restore nucleo cytoplasmic ratio means ploidy of cell remain same.

3. Bcoz of transformation of normal cells into cancerous cells by Carcinogens present in tobacco.,drugs .etc

4 mitosis occurs in plants animals

Binary fission occurs in bacteria and other single celled organism.

Both give rise to two daughter cells.

5.sex cells (n) are produced by meiosis from gamete mother cells(2n).

6.in meiosis ploidy of cell become half

Means diploid cell form haploid cells

And 4 haploid daughters cells are formed.

In mitosis, ploidy of cell remain same

Means haploid form haploid and diploid form diploid.

1 cell form 2 daughter cells.

Hope this helps you.. Frnd ❤️

Last Friday after dealing with the stressors of daily life, Jane was likely to ________________________ in her blood stream.

sineoko [7]

Last Friday after dealing with the stressors of daily life, Jane was likely to have increased level of cortisol in her blood stream.

Explanation:

Daily life activities, responsibilities, duties, events all leads to a lot of stress among individuals. This stress affects our body, thoughts, mind, feelings and behavior.

Cortisol is a stress hormone secreted by the adrenal glands by the triggering of adenocorticotropic hormone of the pituitary gland.

Stressors due to daily life activities and other health problems leads to cortisol awakening response and increases the level of cortisol in the blood stream in order to cope up with the increased stress.

Increased cortisol levels causes a number of health issues like anxiety, depression, headache, digestive issues, cardiac problems, sleep disturbance, cognitive impairment etc
