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
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) - 0.71Thus, carbohydrates like glucose and sucrose are probably the two most common organic molecules that organisms require to produce short-term energy from cellular respiration.

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

Sophie says dolphins and sharks look very similar, so they must be related. Jake disagrees, saying DNA evidence has shown that dolphins and other aquatic mammals are actually more closely related to the ancestors of modern hippos. Who is correct using the modern system of classification?
Sophie is correct because dolphins look more like sharks than like hippos.
Jake is correct because classification is based on evolutionary relationships.
Both are correct because traditional and modern classifications can overlap.
Neither is correct because neither is taking into account both the traditional and modern systems
According to the modern system of classification, Jake is correct because classification is based on evolutionary relationships. So, the correct option is B.
What do you mean by the modern system of Classification?The modern system of classification was invented in order to identify the evolutionary relationships between the organisms that could be more accurately depicted.
Shark belongs to the group of fishes, while dolphin belongs to the group of mammals. They are more or less looking very close to each other. But the modern system of classification reveals the differences between the. And DNA evidence has shown that dolphins and other aquatic mammals are actually more closely related to the ancestors of modern hippos.
Therefore, according to the modern system of classification, Jake is correct because classification is based on evolutionary relationships.

Prompt 3: Why do you think it is so
important to have producers
(autotrophs), consumers
(heterotrophs), and decomposers
(detritivores) in an ecosystem?
Answer:
there will have to be something to produce all the food so that other animals can eat
Explanation:
the consumers are important as when they eat they can have a high possibility to not starve to death as they have competition and can reproduce and then there is a possibility that that animal species may not become extinct
also when u eat u decompose so they are inportant as they decompose
as when they decompose they lay fertilisers for the soil in the floor so that other plants can grow amd flourish so the cycle can continue

Which is the best example of water regulating an organism’s body temperature? a jogger sweating after a run a fish passing water over its gills a deer taking a drink from a stream a leaf using water for photosynthesis
Answer: A. Jogger sweating after a run.
Explanation: I took the quiz. ;)
The best example of water regulating an organism’s body temperature is a fish passing water over its gills, which is the second option, as the fish gill maintains the body temperature and maintains the oxygen and carbon dioxide concentrations too.
What is the significance of the water-regulating system in an animal body?The water-regulating system in an animal body maintains homeostasis in the body, such as electrolytes homeostasis, such as ions such as sodium and potassium in body fluids, and the lungs ,skin, play a role in regulating water balance through respiration and sweating to maintain temperature of the body.
Hence, the best example of water regulating an organism’s body temperature is a fish passing water over its gills, which is the second option, as the fish gill maintains the body temperature and maintains the oxygen and carbon dioxide concentrations too.

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