Which of the following would be an example of osmosis?

Biology

Kipish [7]3 years ago

Answer:

D

Explanation:

An example of osmosis occurs when a sugar solution and water, top, are separated by a semipermeable membrane. The solution's large sugar molecules cannot pass through the membrane into the water. Another good example of osmosis would be dipping a sponge into water, because there is a higher concentration outside, so the water goes in and makes the sponge expand

Answer:

B) the shriveling of a cell after salt is poured on it

Explanation:

During osmosis, water moves from a low concentration to a high concentration. Since the salt is outside the cell membrane, it makes the outside have a higher concentration than the inside of the cell; causing the water to move from the cell and the cell shriveling.

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.

The process of __________ generates the oxygen that we breathe and the food that we eat. view available hint(s)for part a photos
Luden [163]

According to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.

<h3>What is photosynthesis?</h3>

It is the process of obtaining energy from plants, algae and certain bacteria to synthesize organic substances from other inorganic ones.

This metabolic process carried out by some cells of autotrophic organisms is essential for life since, starting from light and inorganic matter, it manages to synthesize organic matter and allows carbon dioxide (CO2) to be fixed from the atmosphere and oxygen to be released.

Therefore, we can conclude that according to the research, the correct option is photosynthesis. The process of <u>photosynthesis</u> generates the oxygen that we breathe and the food that we eat.

Alu element at the PV92 locus on Chromosome 16. In this population, 436 people have a heterozygous genotype and 102 people have
Lesechka [4]

Answer:

Explanation:

According to the exercise we can infer that for the Alu insert:

p: positive allelic frequency

q: negative allelic frequency

maintaining that the population is in equilibrium we can carry out the following formula

p + q = 1 and pp + 2pq + qq = 1

looking for the genotype frequency we clear and obtain the following data

genotype frequency of 2pq = 436/1000 = 0.436

The genotype frequency of qq = 102/1000 = 0.102

This is how we look now:

number of positive people for Alu = 1000- (436 + 102) = 1000- 538 = 46

In this way it is resolved that:

genotypic frequency of pp = 462/1000 = 0.462

  p = 0.462 + (0.436 / 2) = 0.462 + 0.218 = 0.680

q = 0.102+ (0.436 / 2) = 0.102 + 0.218 = 0.320

According to the exercise carried out it is deduced:

The value of p in the population is = 0.68

We conclude that our prognosis showing a homozygous positive genotype is: 0.462
