Define the term peristalsis and explain why is it so important

Answers

Answer 1

Answer:

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. ... There, the food is churned into a liquid mixture called chyme that moves into the small intestine where peristalsis continues. Stretching out a piece of intestine will make it easier to see the wave-like motion

Answer 2
Peristalsis is a series of muscle contractions. These contractions occur in your digestive tract. Peristalsis is also seen in the tubes that connect the kidneys to the bladder.

Peristalsis is an automatic and important process. It moves:

Food through the digestive system
Urine from the kidneys into the bladder
Bile from the gallbladder into the duodenum
Peristalsis is a normal function of the body.

Answers

Answer:   The correct answer is A. nucleic acids.

Explanation:   The genetic information is stored in the form of nucleic acids i.e. deoxyribonucleic acids (DNA) or ribonucleic acids (RNA).

Nucleic acids are large macromolecules in cells and viruses. Nucleic acids store and express genetic data. Therefore, option (A) is correct.

What are nucleic acids?

The biopolymers and macromolecules known as nucleic acids are fundamental to every known type of living being. Nucleotides, which are the monomers that make up nucleotides, are composed of a 5-carbon sugar, a phosphate group, and a nitrogenous base. They are the building blocks that make up nucleotides. Deoxyribonucleic acid and ribonucleic acid are the two primary subgroups that can be found among nucleic acids.

Nucleic acids, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are responsible for carrying genetic information. This information is read in cells and used to produce RNA and proteins, which are necessary for the functioning of living things.

Discuss the unique properties of water. (Polar, Hydrogen bonds, Cohesion, Adhesion)

Answers

Answer:

Water has cohesive and adhesive properties.

Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.

Adhesion and cohesion are important water properties that affects how water works everywhere, from plant leaves to your own body. ... Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.

Answer & Explanation:

The difference in electronegativity between oxygen and hydrogen atoms creates partial negative and positive charges, respectively, on the atoms.

Water molecules attract or are attracted to other polar molecules.

Molecules that do not dissolve in water are known as hydrophobic (water fearing) molecules.

Because of its extensive hydrogen bonding, water (H2O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size. Water is also a good solvent for ionic compounds and many others because it readily forms hydrogen bonds with the solute.  

Cohesion holds hydrogen bonds together to create surface tension on water.

Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.

Water is transported in plants through both cohesive and adhesive forces; these forces pull water and the dissolved minerals from the roots to the leaves and other parts of the plant.

Key Terms:

hydrogen bonds: A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

adhesion: The ability of a substance to stick to an unlike substance; attraction between unlike molecules

cohesion: Various intermolecular forces that hold solids and liquids together; attraction between like molecules

hydrophilic: having an affinity for water; able to absorb, or be wetted by water

hydrophobic: lacking an affinity for water; unable to absorb, or be wetted by water

polarity: The intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule.

Emissions from landfills

Answers

Answer:

i think its C) Freezing of perma frost

Explanation:

The option that does not describe a source of greenhouse gases is the freezing of glaciers. Thus, the correct option is C.

What are greenhouse gases?

Greenhouse gases may be defined as those gases that are present in the earth's atmosphere and trap the heat and radiation from the sun and emitted toward the earth.

Such greenhouse gases are responsible for the greenhouse effect that ultimately leads to global warming.

Steaming and burning of fossil fuels and emissions from landfills extremely liberated the high amount of carbon dioxide in the atmosphere which is one of the most potent greenhouse gas.

Therefore, the option that does not describe a source of greenhouse gases is the freezing of glaciers (hailstone). Thus, the correct option is C.
