If you have a container with hydrogen atoms and oxygen atoms in it do you automatically have water?

Answers

Answer:

no

Explanation:

you have to have the right amount and the right situation for it to turn into water. for instance The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.

how do infrared waves, uv waves,and microwaves affect us

Answers

Answer:

Here is your answer

Explanation:

Infrared radiation has a longer wavelength and lower frequency than visible light. Too much exposure can damage your eyes and skin. On a global scale, trapped infrared radiation contributes to global warming.

UV rays, either from the sun or from artificial sources like tanning beds, can cause sunburn. Exposure to UV rays can cause premature aging of the skin and signs of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis. UV rays can also cause eye problems.

Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn.  But these types of injuries – burns and cataracts – can only be caused by exposure to large amounts of microwave radiation.

Which of the following molecules supplies the main source of short-term energy used in cellular
respiration?
F) Enzymes
G) Carbohydrates
H) Lipids
J) Proteins

Answers

Answer:

g

Explanation:

its g because thats right may i have brainlyist i need it to upgrade

The molecules supply the main source of short-term energy used in cellular respiration is - G) carbohydrates.

All living organisms carry out cellular respiration in order to get energy for cellular processes. All biomolecules proteins, lipids, and carbohydrates provide energy by breaking down during this process. however, sugar molecules or carbohydrates are used to provide short-term and immediate energy in the form of ATP by cellular respiration.

Proteins -

During extreme starvation when all carbohydrates and fats in the body are used up.The respiratory quotient (RQ) of proteins - 0.83–0.9.

Carbohydrates-

The major respiratory substrate is in form of glucose or carbohydrates in cells.The respiratory quotient (RQ) of carbohydrates - 1.

Fats-

used only if carbohydrates are in short supply. It yields almost twice as much energy as carbohydrates generally do not use.The respiratory quotient (RQ) - 0.71

Thus, carbohydrates like glucose and sucrose are probably the two most common organic molecules that organisms require to produce short-term energy from cellular respiration.

Describe the four major spheres that support life on Earth.
Explain how rays AB and AC form both a line and an angle.

Answers

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

Two rays AB and AC having the same endpoint are opposite rays if they two rays are unequal but line AB is equal to line AC. Otherwise they are nonopposite. An angle is the union to two nonopposite rays AB and AC sharing the same endpoint. The angle is denoted by either angle BAC or angle CAB.
