How does the water on earth regulate the earth temperature
Answer:
It absorbs a lot of the sun’s energy.
Explanation:
A large portion of the sun’s energy and heat is absorbed by the oceans, which causes water to evaporate. Water has a high heat capacity, and therefore absorbs a large portion of the sun’s heat, regulating the earth’s temperature.

If you move farther away from Earth, does it have the same amount of
gravitational force acting on you or does it change?
Answer:
The strength of the force is inversely proportional to the distance squared. The farther away an object is, the weaker the force; the closer, the stronger.
How do chemicals made by organisms help establish and maintain a uniform distribution pattern?
Answer:
they in a current form is too unspeakable
The chemicals made by organisms help to establish and maintain a uniform distribution pattern which makes the individuals space out evenly and prevents unwanted enemy.
What is Uniform distribution pattern?In a uniform distribution, the different individuals are equally spaced apart from each other, as seen in the negative allelopathy where various chemicals kill off the plants surrounding sages. In a random distribution, individuals which are spaced at unpredictable distances from each other, as seen among plants that have wind-dispersed seeds on them.
The chemicals synthesized by organisms help to establish and maintain a uniform distribution pattern because it makes individuals to space out evenly in the area and prevents unwanted enemy.

Plz mark brainliest:)
Two products of the Krebs cycle are NADH and FADH2.
What is the Kreb's Cycle?The Krebs cycle is a form of chemical reaction that is meant to convert the energy stored in the body in the form of acetyl CoA to other constituents.
Some products of the Krebs Cycle also known as the Citric acid cycle are Nicotinamide adenine dinucleotide and Flavin adenine dinucleotide. The energy released is from carbohydrates and fat.

APT and photovoltaic cells are simikar because
The question is incomplete, below is the complete question.
ATP and photovoltaic cells are similar because
A. they are both key components of plant cells.
B. they both produce chemical and electrical energy.
C. they are both key components of solar panels.
D. they both use energy from the sun to separate electrons from atoms.
The correct answer to the question is option D
ATP and photovoltaic cells are similar because THEY BOTH USE ENERGY FROM THE SUN TO SEPERATE ELECTIONS FROM ATOMS.
Photovoltaic cells are otherwise known as solar cells,they are made of silicone that are specially treated,these specially treated silicon transfers solar energy gotten from the sun to electrical energy.
These solar powered photovoltaic panels converts the rays from the sun into electricity.this it does by exciting electrons found in silicon cells and also using the photons of light from the sun.
When this electricity is generated,it can be used to supply energy that is renewable to ones home or business.
In ATP, during the process of photosynthesis, sunlight penetrates the cell and further pass into the chloroplast. This light energy is further intercepted by granal stacks containing chlorophyll molecules, from then,some of those light energy are concerted to chemical energy,as this is going on,a phosphate is then added to a molecule to give rise to ATP.

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins
Answer:
Estradiol has a higher partition coefficient than H+ ions
Explanation
Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.

What is a pathway for an atom (carbon)
Answer:
-- --
)____(
Explanation:
The carbon atom can make a transition between photosynthesis and respiration because the carbon atom is both a reactant and a product. For example, plants take in carbon dioxide for photosynthesis which releases oxygen. Then other organisms use this oxygen for respiration, which releases carbon dioxide.n:
Why are carbon important to these molecules
Answer:
Hiya! ^^
Explanation:
Carbon's molecular structure allows it to form bonds with many elements, itself other carbon elements. Because of this, it can form long chain molecules, each having different properties. Carbon remains in balance with other chemical reactions in the atmosphere and water because of its stability.

Explanation:
Which of the following is TRUE about the fossil record? Group of answer choices It is sadly incomplete and lacking in all transitional forms. It gives useful information about environments and the ways past organisms lived. Only animals with hard skeletons are preserved. It is best in deep forests where dead organisms have not been disturbed.
Answer:
It gives useful information about environments and the ways past organisms lived
Explanation:
A fossil is basically any preserved remains or trace of any organism that once lived in the past. Bones, shells and exoskeletons are examples of fossils that can be studied through Paleontology.
From fossil studies, we can tell how long these lives existed on earth and how varying plants and animals are related to one another. We can often find out how and the places they lived and their environments as well.
