As part of an experiment, you grow some plants in an environment including carbon dioxide with radioactive carbon isotope 14C as a tracer. After a few days you take the plants out and look for the tracer. You find it primarily in the roots. How did it get there? Why is it in the roots?

Answers

Answer 1

Answer:

Plants make their own food with the help of photosynthesis, in which the organic carbon is formed from the inorganic carbon. Organic carbon is used as a source of energy and helps in various cellular functions.

Organic carbon mostly stored in the form of starch and other carbohydrates and also helps in forming the structure of the plants. The starch is stored mainly in the roots, fruits and stems. The main source of starch is in roots in tubers of the plants. The radioactive carbon that is found in the plant roots in the experiment is the excess carbon that stored in the roots of the plants

Maltase is an enzyme that catalyzes the hydrolysis of the disaccharide maltose. This process occurs during human digestion when maltase is secreted by the intestine and then converts maltose into glucose. Which two classes of biomolecules are directly involved in this process?

A .proteins and carbohydrates

B. lipids and proteins

C. carbohydrates and nucleic acids

D. carbohydrates and lipids

Answers

Answer: D

Explanation:

Carbohydrates and nucleic acids are the two main classes of biomolecules which are involved directly in the process of digestion of maltose through maltase enzyme. Thus, the correct option is D.

What is Maltase?

Maltase is a an enzyme which belongs to the alpha-glucosidase enzyme family. These are found in the small intestine's brush bordered cells. The hydrolysis of the disaccharide maltose into two simple sugars such as glucose is catalyzed through the enzyme maltase.

Maltose is a disaccharide which is produced by the enzymatic hydrolysis of starch, which is a homopolysaccharide and this is catalyzed by the enzyme amylase. Maltose sugar is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose.

Therefore, the correct option is D.

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.

Explanation:

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.

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.

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.

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.
