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.
The nervous system may be compared to a "
A computer
B trash removal company
C highways in a city
D water filtration center
Answer:
A. A computer
Explanation:
The way your nervous system works can be compared to how your computer works. When you press the power on your computer, a signal goes out. The signal is a catalyst that generates a number of actions and responses. An electric current travels over the wires maintaining a connection to electricity
The nervous system may be compared to a computer. So, the correct option is A.
What is Nervous system?The nervous system is defined as a highly complex part of an animal that coordinates its functions and sensory information through the transmitting signals from different parts of its body. This system includes
1. The central nervous system consists of the brain and spinal cord)
2. The peripheral nervous system consists of the nerves that extend from the spinal cord to the rest of the body
3. Other nerve tissue.
The nervous system may be compared to a computer. The way our nervous system works can be compared to the way your computer works. When we press power on computer a signal comes out like CNS and PNS work in the body
So, the correct option is A.

: Is a human leg prosthetic an example of science or technology? Explain your answer.
QUICK!!!! ANSWER PLEASE WITH EXPLANATION TOO!!!
Answer:
This would be an example of technology.
Explanation:
Artificial limbs, or prostheses, are used to replace a missing body part which may have been lost due to trauma, disease or congenital defect. The type of prosthesis a person can use is dependent on the individual, including the cause of amputation or limb loss, and the location of the missing extremity. These come in all shapes and sizes, for whatever you need.
Have a nice day!
Answer:
A technology, since the actual prosthesis is a human creation that solves a problem. Science is nothing physical. It is the combination of laws and theories that explain our universe and helps us make decisions. We don't really invent science, we describe it.
Science is ideas. Technology is human creations.
Science generally underpins all new technology.
In your human leg prosthesis example science is crucial in choosing (or developing) suitable materials for construction of the prosthesis. The material must be relatively stable, not break down into toxic substances and have good durability. Knowledge of human Biology is also important if you want to start replacing human body parts.
Basically chemistry and biology are important in the prosthesis development. There is also probably physics regarding tensile strength requirements.
The actual end result of the human prosthesis is a technology which solves a problem of degraded human parts.
So to reiterate, it is a technology.

What is NOT a function of the
nucleus?
A. Directs protein synthesis
B. Houses DNA
C. Functions as the powerhouse of the cell
Answer:
function as the powerhouse of cell
Explanation:
we have read the power house of cell as a mitochondria
==========================================================
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.

Commensalism is a symbiont relationship in which there is a relationship between two organisms in which one gets benefits and the other organism is unaffected.
Human skin has many commensal bacteria that fed on dead cells of the skin. Here humans are hosts that do not get harm and bacteria rely on them for survival.
11. Describe how the climate most likely changed between 220 million and 12 thousand years ago
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.

Why has the demand to find more than fossil fuels for energy increased?
Explanation:
Global energy demand is increasing due to industrial activity and advances in both developing and developed countries. ... The GHGs from geothermal energy systems for electrical power production and space heating applications are much lower than those from conventional fossil fuel energy systems [3,4].
Answer:
Explanation:
The demand for energy across the world is constantly rising. This increased demand is caused in part by the increase in population, and by economic development. It is because these areas experienced large-scale economic development, their original energy sources were fossil fuels – first coal and oil and gas.
