____________________________________________________________________________________________________________________________________________________________

Answers

Answer:

All ecosystems are made up of abiotic and biotic components.

biotic factors are living things, such as plants or animals.

abiotic factors are nonliving things, such as wind, temperature, or moisture.

producers are organisms that get their energy from nonliving resources, meaning they make their own food. These organisms are also called autotrophs.

consumers are organisms that get their energy by eating other organisms. These organisms are also called heterotrophs.

Why are producers so important to an ecosystem?

They create the base of the food chain/food web

Explanation:

The answers can be explained as:

1.Ecosystem is made up of biotic and abiotic compoenents. Biotic components refer to the living things whereas the abiotic components are the water, soil, air, and minerals.

2. Biotic factors are the living components of the ecosystem, which are plants, animals, and microorganisms.

3. Abiotic factors are the non-living components, which include moisture, temperature, air, and minerals.

4. Producers are the organisms that prepare food in the presence of light, water, and gases. These organisms are also plants or autotrophs.

5. Consumers are the organisms that feed on the producers to obtain energy. These organisms are known as heterotrophs.

6. Producers are the organisms that prepare food for the organisms. These are essential for the ecosystem as all organisms are dependent on each other and require food for survival.

Where does sugar enter the blood? B. How can you tell where sugar enters the blood? C. Where is sugar removed from the blood? D. How can you tell?

Answers

Answer:

Well,

Explanation:

For your first question, the intestines.

B.When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.

C. The capillaries.

D. Glycogen is mainly stored in the liver (where it makes up as much as 10% of liver weight and can be released back into the blood stream) and muscle (where it can be converted back to glucose but only used by the muscle). Therefore, excess glucose is removed from the blood stream and stored. In short terms, when it has the lowest content.

Blood sugar or glucose is the major source of energy found in the body. It is derived from the food and nutrient an organism consumes.

A. The blood sugar enters the intestine, where it gets digested. This absorbed sugar then gets discharged in your blood from where it diffuses in the body as a source of energy.

B. The food in the stomach gets divided into smaller, simple compounds as the carbohydrates split into sugar and starch.

It further gets divided into glucose which is the simplest sugar. The glucose then gets absorbed by the stomach and intestine which later discharges into the blood.

C. The excess glucose gets expelled from the blood capillaries and gets stored in the form of glycogen.

D. The excess glucose in the form of glycogen gets collected in the liver cells and muscles, where they can be transformed back into glucose through the process of glycogenolysis.

Answers

Answer:

1. The clownfish and anemones both benefit

2. The herbivore that feed on producers

3. Ant, grass and snail

4. True

5. Commensal

Explanation:

1. The clownfish and anemones both benefit  - the clownfish benefit by gaining protection from predators, the anemones benefit from the prey being attracted

2. The herbivore that feed on producers - biotic factors are living factors. Oxygen, sunlight, and climate are all abiotic (non-living)

3. Ant, grass and snail  - biotic factors are living factors. Temperature, pH, and rainfall and humidity are all abiotic (non-living)

4. True - At least one organism benefits. The other organism might also benefit (mutualism), be unaffected (commensalism), or be harmed (parasitism)

5. Commensal - commensalism is when one organism benefits and one organism is not harmed or benefited by the interaction

Which of the following pairs of chemicals are understood to be the chemical
reactants in photosynthesis and the products of cellular respiration?
A
Sugar and water
B
Carbon dioxide and oxygen
с
Sugar and oxygen
D
Carbon dioxide and water

Answers

The answer is D) Carbon dioxide and water.

Hope this helps! :)

The pairs of chemicals that are understood to be the chemical reactants in photosynthesis and the products of cellular respiration are Carbon dioxide and water. Thus, the correct option for this question is D.

What is Photosynthesis?

Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.

The complete reaction of photosynthesis is as follows:

[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6CO_2+6H_2O[/tex].

With the help of this reaction, it is understood that the reactants of photosynthesis are carbon dioxide and water. While these compounds are the product of cellular respiration along with the derivation of energy in the form of ATP.

Therefore, carbon dioxide and water are the pair of chemicals that are understood to be the chemical reactants in photosynthesis and the products of cellular respiration.

How do radio telescopes help advance our knowledge of our universe?

Answer:

Raido telescopes can sense signals way out in space seening things that we havent seen yet therefore futhering our knowlege of the universe

Explanation:

To investigate naturally occurring radio radiation from stars, galaxies, black holes, and other celestial phenomena, we utilize radio telescopes.

What are radio telescopes?

They may also be used to send and receive radio waves that are reflected from the planets in our solar system.

Planets, comets, massive clouds of gas and dust, stars, and galaxies may all be seen with radio telescopes as they point toward the skies. Astronomers can discover information about these objects' composition, structure, and motion by examining the radio waves they emit.

We can learn more about these hot regions, which emit radio waves, with the use of radio telescopes. Our solar system's planets also have radio personalities.

Therefore, radio telescopes display the motion of the gas clouds that whirl around Uranus and Neptune, and the north and south poles of Jupiter emits radio waves.

Explanation:

This question involves a single gene coding for flower color in four oʼclock plants. The alleles for red flower (R) and white flower (W) exhibit incomplete dominance, hence, results in a third phenotype that is pink (RW).

If two pink flowered four oʼclock plants were crossed i.e. RW × RW, the following gametes will be produced by each parent

RW - R and W

Using these gametes in a punnet square (see attached image), the following genotype and phenotype of offsprings will be produced.
