The statement best describes the energy needed for photosynthesis and cellular respiration to take place is photosynthesis and chemical energy is need for the process.
What is the first step of cellular respiration?Glycolysis has been known as the first step of the cellular respiration. During this process molecules of the glucose break down in order to form the pyruvate molecules including 2 ATP molecules.
During the process of glycolysis there has no requirement of the oxygen. Therefore, the process has been known as the anaerobic process. During the process of the glycolysis glucose which has been converted into the pyruvic acid and energy has been released for the formation of the high energy molecule.
The process of photosynthesis takes place in the green plants and during the process of photosynthesis green plants prepare their own food in the presence of sunlight and the process is known as photosynthesis. During this process heat energy converted into chemical energy.
Therefore, The statement best describes the energy needed for photosynthesis and cellular respiration to take place is photosynthesis and chemical energy is need for the process.

in terms of structure, how do channel proteins differ from carrier proteins?
Answer:
Moreover, carrier proteins can carry out both active and passive transportation of solutes, whereas channel proteins bring about passive transport only. Both carrier proteins and channels proteins also differ in their chemical composition - whilst the former are glycoproteins, the latter are lipoproteins.
Explanation:
hope this helped you if it did please mark brainiest
Carrier proteins can carry out both active and passive transportation of solutes, whereas channel proteins bring about passive transport only.
What are the functions of carrier proteins?Carrier protein is a type of cell membrane protein involved in facilitated diffusion and active transport of substances out of or into the cell. Carrier proteins are responsible for the diffusion of sugars, amino acids, and nucleosides.
Moreover, carrier proteins bind specific solutes and transfer them across the lipid bilayer by undergoing conformational changes that expose the solute-binding site sequentially on one side of the membrane and then on the other.
Membrane carrier proteins are important transmembrane polypeptide molecules which facilitate the movement of charged and polar molecules and ions across the lipid bilayer structure of the cell membranes.

(Plz help)
In reference to the options listed in the image, we can say that protein pumps are efficient because they can move two types of molecules, which makes option B correct.
A protein pump is a kind of protein, often found in the cell membrane, that has the capability to pump specific substances in and out of the cell. Most of the processes that happen at the cellular level are naturally optimized for efficiency, even when the process consumes energy, as is the case with the protein pump.
The reason that the protein pump is considered efficient lies in how it uses the energy. Despite being an active process that consumes ATP to function, protein pumps are considered efficient because they can move two types of molecules at the same time, using the same molecule of ATP. This allows the cell to get more done for the same amount of energy.

which of these is a source for particulate matter in the air?
Answer:
Particulate Matter (PM) Sources Components of particulate matter (PM) include finely divided solids or liquids such as dust, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapors that can be suspended in the air for extended periods of time.
Explanation:
Automobiles, dust, and fires are source for particulate matter in the air. Therefore option D is correct.
Particulate matter (PM) refers to tiny particles suspended in the air that can have harmful effects on human health and the environment. Sources of particulate matter in the air include automobiles, dust, and fires.
Automobiles emit exhaust emissions that contain particulate matter, especially from diesel engines. Dust particles can be generated from various sources such as construction sites, unpaved roads, and agricultural activities.
Fires, including both wildfires and controlled burns, release smoke and ash particles into the air. These particles can vary in size and composition.
All of these sources contribute to the presence of particulate matter in the atmosphere, and their emissions can have detrimental effects on air quality and public health if not properly managed or controlled.
Therefore option D all of the above is correct.

Which phrase describes transmutation?(1 point) the conversion of protons to neutrons through nuclear changes the conversion of one substance to another through chemical changes the conversion of an atom of one element into a different element through nuclear changes the conversion of energy to matter through chemical changes
Answer:
B
Explanation:
PLEASE MARK AS BRAINLIEST!!!!!Transmutation is conversion of an atom of one element into different element through nuclear changes.
Transmutation consists of the conversion of stable nuclei into other nuclei if they are bombarded by fast particles.
Specifically, an atom can be transmuted by making particles or atoms collide with it at high speed, that is, to accelerate a particle is to increase its speed by some mechanism that imparts energy to it.
Thus, the transmutation of an element requires that there be a change within its nucleus, and in particular in the number of protons.
The neutrons or protons must have enough energy to overcome the nuclear forces that prevent their passage or exit from the nucleus of the atom to be transmuted.
Therefore, we can conclude that transmutation is conversion of an atom of one element into different element through nuclear changes.

What is a snake that eats a mouse an example of?
predation
competition
mutualism
parasitism
Answer:
Predation
Explanation:
A snake that eats a mouse an example of predation.
A snake that eats a mouse is an example of predation. Predation is an ecological interaction where one organism (the predator) kills and eats another organism (the prey). Hence option A is correct.
What is predation?Predation is an ecological interaction between two organisms in which one organism (the predator) hunts, kills, and eats another organism (the prey). It is a form of consumption where the predator obtains nutrients and energy from the prey, while the prey is typically harmed or killed in the process.
In this case, the snake is the predator and the mouse is the prey. Predation is a natural and common interaction in many ecosystems, and it can have significant effects on population dynamics and community structure.
It can help regulate prey populations, prevent overgrazing, and promote species diversity.
Predators have evolved various adaptations to catch and kill their prey, while prey has evolved various defenses to avoid being eaten, such as camouflage, warning coloration, and physical or behavioral defenses.
Hence option A Predation is correct.
