what does the mitochondria do to produce a ton of energy

Answers

Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. ... NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds.

If a person has brown hair, what genotypes might they have?

Answers

Answer:

Genotype is the genetic makeup of an individual. Phenotype is the physical appearance of brown hair.

Hello, I Am BrotherEye

Answer:

Genotype is the genetic makeup of an individual eg Bb. Phenotype is the physical appearance eg brown hair.

Explanation:

Your genotype codes for your phenotype — the trait we can actually see. For example, if the blue-eyed parent passed down a blue allele, and the brown-eyed parent passed down a brown allele, the child's genotype will be blue-brown, and his or her phenotype will be brown.

Do you think an international orbiting space station is a good idea? Why or why not?

Answers

Answer:

Yes it is (we already have one)

An international orbiting space station would be a great idea! We could use the space station as a refueling point for passing spaceships. This could helps us achieve things such as space exploration, mars/moon colony, or even contact with other unearthly organisms. This could also allow us to conduct space research.

No it isn't

An international orbiting space station is a horrible idea! The first thing to think about is the money. This would put the entire area in stasis as we try to raise money for the space station. We also need contact with the humans/robots in space! Building a space station would confuse other nations as to what we plan to do with said space station. This could cause a war of some sort.

How does the level of surface water affect the amount of water vapor in the air?

Answers

if there’s more surface water then there will be more water vapor in the air (if the climate is warm then that will also increase the amount of water vapor because warm air can hold more water )

If there’s more surface water then there will be more water vapour in the air if the climate is warm then that will also increase the amount of water vapour.

What is condensation answer?

Condensation is the method where water vapour becomes liquid. It is the knock of evaporation, where liquid water becomes a vapour.

 the air is cooled to its vapour point or it becomes so soaked with water vapour that it cannot hold any more water.

Thus, the level of surface water affects the amount of water vapour in the air.

Write an argument for or against the following statement. The energy humans use in cars originally came from the Sun.

Answer in paragraph form using 5-7 complete sentences.

NO LINKS!!!!!!

Answers

do the energy humans use in their cars actually originate from the sun? they do! most products like oil, gas, and coal actually come from the sun. the reason why i say this is because all those things are natural which means they came from photosynthesis. according to the site  (Where Does the Energy in Fossil Fuels Come From? http://techalive.mtu.edu) "So, in one sense, gasoline-burning cars, coal-burning power plants, and homes heated by natural gas are all solar powered!"

Explanation:

True. All of the energy in coal, gas, and oil was first stored by the sun through photosynthesis. Hence, in a certain sense, solar power is used by gasoline-powered vehicles, coal-fired power plants, and residences heated with natural gas.

What is Energy?

In order to accomplish work and to produce heat and light, energy must be transferred to the a body or to a physical system. Energy is the quantitative attribute that does this. Energy is a preserved resource; according to the rule of conservation of energy, energy can only be transformed from one form to another and cannot be created or destroyed.

Energy is the ability to do tasks. It could exist in several different forms, such as potential, kinetic, thermal, electrical, chemical, radioactive, etc. Moreover, there is heat and work, which is energy being transferred from one object to another. Energy is always assigned based on its nature once it has been transmitted. Hence, heat transmitted may manifest as thermal energy while work performed may result in mechanical energy.

Thus, all of the energy in coal, gas, and oil was first stored by the sun through photosynthesis. Hence, in a certain sense, solar power is used by gasoline-powered vehicles, coal-fired power plants, and residences heated with natural gas.

Thank you pls give brainiest ! :)

The statement that best describes the roles of photosynthesis and respiration in the carbon cycle is:

Respiration adds carbon to the atmosphere, while photosynthesis removes carbon from the atmosphere.

What is the carbon cycle?

It comprises a succession of transformations or exchange of matter (specifically carbon-containing compounds) between the biosphere, the pedosphere, the geosphere, the hydrosphere and the Earth's atmosphere.

Characteristics of the carbon cycle

The carbon in CO2 is taken up by plants and released along with water vapor during animal respiration.

Respiration and photosynthesis along with other metabolic biotic processes, these processes respectively release and capture carbon dioxide from the atmosphere, as a by-product or input of their biochemical pathways.

Therefore, we can conclude that during photosynthesis, plants absorb carbon dioxide from the air and the oxygen not consumed in respiration passes to the atmosphere, being essential in the biogeochemical cycle of carbon.

But Morse code serves as a ____ that we can use to understand ___ ___ is __ and ___ through optical fibers as light waves.

Answers

Answer:

In modern communications, such as Internet, cable TV, and telephone communications, information is sent via signals in laser light through clear cables called optical fibers, which are also known as fiber optics. Optical means it has to do with light waves.

The information must be encoded to be sent as patterns of light. One model of how information can be encoded is Morse code. Actual Internet data, cellular phone, and TV signals are not sent by Morse code. But Morse code serves as a model that we can use to understand how information is encoded and sent through optical fibers as light waves.

Actual Internet data, cellular phone, and TV signals are not sent by Morse code. But Morse code serves as a model that we can use to understand how information is encoded and sent through optical fibers as light waves.

 

Optical fibers carry information for very long distances by using total internal reflection. The information is encoded as light. We will learn more later about how this code is created and used. Light waves travel very fast. Information sent from New York by fiber optics could reach Australia in less than 1/10 second.

Fossil fuel production is another human activity that places considerable strain on drinking water — and not just because fracking and coal mining use a great deal of water, but because their waste products can pollute groundwater, and therefore drinking water, as well.Water resources face a host of serious threats, all caused primarily by human activity. They include pollution, climate change, urban growth, and landscape changes such as deforestation. Each of them has its own specific impact, usually directly on ecosystems and in turn on water resources.

describe an experiment (using 3-5 complete sentences) that you could conduct to test whether or not humans can see in complete darkness. Make sure to include your independent and dependent variables.

Answers

Answer:

An experiment that I could conduct to test whether or not humans can see in complete darkness is by simply going into a place where I know it would be pitch black if I turned off the lights. Such as an basement or closet. I could have a friend or family member place an object close to me in the same room. Once the lights have been shut off I could easily try and find it. I have tried this experiment using a friend and myself. I could find the object just by trying to use things near me to guide myself and eventually found it. My friend on the other thought that they didn't need to use any senses to find the object but failed sadly. I say that my way of working my way to the object in the dark was most helpful because if you are familiar with your surroundings it could make things a lot easier. If you try not to use senses to help yourself in the dark things could get dangerous. You could either run into something or get hurt or end up grabbing the wrong thing.
