Which of the following best describes the hydrolysis of carbohydrates

Answers

Answer:

The addition of a water molecule breaks a covalent bond between sugar monomers

Explanation:

The digestion of carbohydrates by enzymes is an example of a hydrolysis reaction.

Carbohydrates are chains of monosaccharides. Hydrolysis involves the addition of a water molecule that cleaves the covalent bond between the molecules of sugar.

The reverse reaction is a condensation reaction, the joining of sugar monomers to create a carbohydrate releases a molecule of water.

Describe the difference between the different forms of electromagnetic
radiation and how scientists classify the types of electromagnetic radiation.

Answers

Answer: Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. Scientists classify them by the frequency of their wavelength, going from high to low frequency. When a wave has a lot of energy, it could be a gamma ray or x-ray. If it has low frequency, it has less energy and could be a TV or radio wave.

oxygen and nitrogen molecule consists of two oxygen atoms bonded to each other and same nitrogen atoms are bonded of each other.

Water molecules have one oxygen atom in the center and two hydrogen atoms, one on each side.

what are the properties of water molecule ?

It has no taste, odor, or transparency, where the nucleus of the oxygen atom  attracts electrons strongly than the nuclei of the hydrogen atoms.

In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of  a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.

Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.

Surface tension is defined as  the tendency of  the surface to resist rupture when they are subjected to stress due to cohesive forces.

Enzymes speed up and direct chemical reactions. TRUE

Enzymes are proteins that act as biological catalysts by way of accelerating chemical reactions. The molecules upon which enzymes may also act are called substrates, and the enzyme converts the substrates into specific molecules called merchandise.

Enzymes carry out the essential venture of lowering a reaction's activation electricity—this is, the amount of energy that has to be installed for the response to begin. Enzymes paintings by using binding to reactant molecules and maintaining them in such a manner that the chemical bond-breaking and bond-forming approaches take place more effortlessly.

Which path shows how gravity causes water to move?(APEX)

Stream , Tributary, River, and Lake

Explanation:

Stream tributary River and Lake is the path for gravity causes water to move.

What is Path for water?

Evaporation, condensation, and precipitation are typically taught as three separate but interconnected stages of the water cycle. Although this is a useful model, the actual situation is far more nuanced.

Water moves through ecosystems on Earth in a variety of ways that are incredibly complicated and still not fully understood.

For better weather, climate, water resource, and ecosystem health forecasting, NOAA is working to increase understanding of the water cycle at all sizes, from the global to the local.

Evaporation, condensation, and precipitation are frequently taught as three basic, circular processes that make up the water cycle. This is a good paradigm, but in practice things are much more nuanced.

Why have plants in the alpine biome adapted to survive on limited nutrients?

Answers

Answer:

The soil in the alpine biome is rocky and nutrient poor.  Plants that live in the alpine biome must be suited to the nutrient poor soil.

Explanation:

The plants living in the alpine biome are adapted to survive on limited nutrients as the conditions in the alpine biome is harsh and not favorable. Hence, the plants have to adapt the mountain climate.

What are adaptations?

An adaptation is any physical or behavioral feature of an organism that helps them to survive better in their environment. In other words, an adaptation is something that helps them in finding food, water, mates, and shelter.

The alpine climate is the typical climate for elevations above the tree line, where the trees fail to grow due to cold conditions. The climate of alpine biomes is also referred to as the mountain climate or highland climate.

Plants which are living in alpine biomes are typically low growing due to the extreme environmental conditions. There are only about 200 species of alpine biome plants which have adapted to life in cold temperatures and sparse rainfall.

If, somehow, the number of daylight hours did not change throughout the year, but Earth
was still tilted at 23.5°, would there still be seasons in the Northern and Southern
Hemispheres of Earth? Would the temperature difference between the seasons still be as
great? Explain your reasoning.

Answers

Answer:

There would still be seasons, because the intensity of light would still change throughout the year, due to the earth's tilt.

Explanation:

If, somehow, the number of daylight hours did not change throughout the year, but Earth  was still tilted at 23.5° then-

Yes, there would still be seasonsNo, the temperature difference between the seasons would not be as great

The tilt of the Earth's axis at 23.5° leads to the different parts of the Earth to gets a high or less amount of direct sunlight at different times of the year.

If there would be no tilt of the earth then there would be no seasons on Earth.If the number of daylight hours did not change then seasons still be there due to the intensity of light would still change throughout the year as the earth is still tilted. If the number of daylight hours did not change throughout the year then the temperature difference would not be as great due to less light in the daytime will not be able to heat enough and the Earth would not be heated for a longer time in summer.

Thus, the correct answer is -

Yes, there would still be seasonsNo, the temperature difference between the seasons would not be as great.
