Answer:

Secondary consumer level = 900 kcal of energy

Producer level = 90000 Kcal of energy

Explanation:

According to this question, there are 9000 kilocalories of energy available at the primary consumer level. Since, only about 10% of energy is transferred from one trophic level to another in a food chain, the following will be available at the secondary consumer and producer level;

Note that:

Producer → primary consumer → secondary consumer

* At the producer level; where x is the amount of energy available at the producer level.

10/100 × x = 9000kcal

10x/100 = 9000

10x = 900000

x = 900000 ÷ 10

x = 90,000 Kcal of energy.

* At the secondary consumer level:

10/100 × 9000

90000/100

= 900 Kcal of energy.

11. Describe how the climate most likely changed between 220 million and 12 thousand years ago

Answers

Answer:

The Earth was formed about 4.5 billion years ago—that's a very long time ago! It's hard to say exactly what the Earth's daily weather was like in any particular place on any particular day thousands or millions of years ago. But we know a lot about what the Earth's climate was like way back then because of clues that remain in rocks, ice, trees, corals, and fossils.

These clues tell us that the Earth's climate has changed many times before. There have been times when most of the planet was covered in ice, and there have also been much warmer periods. Over at least the last 650,000 years, temperatures and carbon dioxide levels in the atmosphere have increased and decreased in a cyclical pattern.

These two clue show how the amount of carbon dioxide and the Earth's temperature have changed over the last 650,000 years. Both clue show a similar up-and-down pattern.

People didn't cause the climate change that occurred thousands or millions of years ago, so it must have happened for other natural reasons.

What is NOT a function of the
nucleus?
A. Directs protein synthesis
B. Houses DNA
C. Functions as the powerhouse of the cell

Answers

Answer:

function as the powerhouse of cell

Explanation:

we have read the power house of cell as a mitochondria

Answer: C) Functions as the powerhouse of the cell

==========================================================

Explanation:

The mitochondria is responsible for generating the cell's energy, hence the phrasing "the mitochondria is the powerhouse of the cell".

The nucleus holds the DNA, so we can rule out choice B. The DNA in turn is connected to forming the proteins. The actual protein synthesis happens in the ribosomes, but the DNA is used as a blueprint (more or less) to assemble the correct amino acids in the correct order to form the complicated protein chains. In short, the nucleus indirectly helps direct the protein synthesis, so we can rule out choice A.
