Which diagram best illustrates the flow of energy in an ecosystem?

Answers

Answer:

The correct answer is - option B.

Explanation:

The diagram or pyramid for the energy flow of an ecosystem represents the flow of energy from one end to the other end according to the food chain. It starts with the ultimate energy source the sun which is used by the producers to produce energy and this is the trophic level that carries the highest energy.

In the food chain, when primary consumers eat the producers they get 10% of the total energy producers carries due to loss of energy and 10% energy of primary consumer have transferred to secondary consumer and so on.

When do the scientists working in the exclusion zone need to wear all of their protective gear? For radioactive wolves

Answers

Answer:

all the time

Explanation:

The radioactive wolves is a documentary film made on the Chernobyl radioactive disaster. This place is known as the Chernobyl exclusive zone and human trespasses is prohibited here.

A team of scientist went to the Chernobyl exclusive zone to do some research on the life of the wild animals in that place after the disaster. A large number of animals now are carrying particles of radioactive elements in their body and is roaming in the forests of the world.

So the scientist visiting the exclusive zone must wear the protective gears all the time they are in the place so as to prevent themselves from exposing themselves to the radio active elements.

Please help, 100 points! Most scientists agree that life began on earth approximately 3.5 billion years ago. What would a scientist need to do in order to test this hypothesis and gather evidence?

A: Recreate the composition of the atmosphere and oceans on Earth as they were 4.5 billion years ago.
B: Travel to a similar planet or moon in its own early formation and recreate the chemical reactions which took place on Earth.
C: Gather the raw materials, such as inorganic compounds, on Earth 4.5 billion years ago and recreate the chemical reactions that could have taken place.
D: This is not a testable hypothesis since there is no way to travel back 4.5 billion years or to run the experiment for the next 4.5 billion years. (This one is obviously wrong)

Answers

I think the answer is A as well, I hope this answers your question

Around 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.

What is the origin of life?

Even before the 3.5 billion years ago when the oldest fossils on Earth were discovered, just at the conclusion of the time of late intense bombardment, there is evidence of biological activity.

The 3.5 billion-year-old "stromatolites," which are hard structures created by bacteria, also provide evidence of their presence. Stromatolites are produced when microbe-made sticky mats catch and organize sediments into layers.

It has been discovered that trophozoites contain organic material from 3.5 billion years ago. 3.5 billion-year-old rocks have been found to contain microbial remnants, some of the planet's earliest evidence of life.

Therefore, 3.8 billion years ago, near the conclusion of this phase known as the late heavy bombardment, life on Earth first emerged, hence option A is correct.

A. concentrates
B. dry roughage
C. green roughage
D. silage
E. dry matter

Answers

Answer:

D.

Explanation:

Answer:

Green Roughhage

Explanation:

Roughages are high in fiber and low in digestible nutrients. There are three kinds of roughages: dry, green, and silage. Dry roughage such as hay has a low moisture content. Grasses in pastures and root vegetables (like turnips) are called green roughage and have a high moisture content. The fermentation of green plants results in the formation of silage.

In one or more paragraphs respond to the question below. Do you think that teaching evolution should be allowed in public schools? Explain your opinion

Answers

Hi there, this is opinion based but here is my take (you can change and add to it if you want, just copy and paste my answer)

Teaching evolution should be allowed in public schools. Yes, many have issues with the fact that evolution would go against many religious beliefs, but it is scientifically proven, and so it should be assessable to everyone. If you were to go work in a place and they ask you what you know about evolution, wouldn’t it be absurd to say “I don’t know because i was never allowed to learn about that subject.” It is completely preposterous to deprive yourself of the reality of what is going on in the world.

Ok that was it. Btw i am indeed a religious person and i still think evolution should be taught, if you were wondering.

2.It lies in the circumstellar habitable zone (CHZ). CHZ is defined in the image given below.

3. Earth has a unique magnetic field which protects the earth from the harmful solar winds. These solar winds played a role in transforming venus into hell.

4. Earth has Van Allen radiation belts which protects it from cosmic rays.

5. Our large neighbour Jupiter protects is from many comets and asteroids that come from the keiper belt and Oort cloud.

6. Earth's atmosphere is favorable to support life on earth. This atmosphere consists of different gases in adequate amount. If the percentage of gases would differ then life on earth may face serious consequences.

7. Tectonic plates of earth differentiates it from most other planets.

8. Earth has a solid crust unlike the gaseous planets.

9. Earth has been gifted with a medium sized star which release solar winds and protect us from the harmful radiation of outer space.
