it a Gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials.
Explanation:
The best explanation of how gravity contributes to the formation of layers in protoplanets is gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials. The correct option is A.
What is gravity?A planet or other body's gravitational pull pulls items toward its core. All of the planets are kept in orbit around the sun by gravity.
The force that draws massed bodies toward one another is known as gravity. Greater gravitational forces are present in bodies with higher masses.
According to the alternatives, gravity pulls things together and causes compaction, which generates heat and causes things to melt, sink, and rise.
Therefore, the correct option is A. Gravity attracts materials and causes compaction, which produces heat and leads to the melting, sinking, and rising of materials.

C Oxygen is a product of cellular respiration.
D Oxygen is a reactant of cellular respiration.
Answer:
D
Explanation:
google cell respiration reaction
The statement which is true about Cellular respiration is as follows:
Oxygen is a reactant of cellular respiration.Thus, the correct option for this question is D.
What is Cellular respiration?Cellular respiration may be defined as a process through which organisms disintegrate the molecules of glucose in order to derive energy in form of ATP in the presence of oxygen.
The complete reaction of cellular respiration is as follows:
[tex]C_6H_1_2O_6+6O_2[/tex] → [tex]6CO_2+6H_2O+ENERGY.[/tex]This important reaction is carried out in the cell organelle known as mitochondria. This is because it is known as the powerhouse of the cell by the derivation of energy in the form of ATP. Although this chemical reaction is carried out in the presence of oxygen, it is known as aerobic respiration.
Therefore, oxygen is a reactant of cellular respiration is a statement which is true about Cellular respiration. Thus, the correct option for this question is D.

Which is one source of the sediments that form sedimentary rocks?

materials dissolved in solutions
Answer:
D - materials dissolved in solutions
Explanation:
EDGE 2021
Most sedimentary rocks are formed in a process that involves water. It is one of the primary factors in the mineral formation of chemical sedimentary rock. Thus, option D is correct.
What role of dissolved materials in the sedimentary rocks?Mineral crusts are formed on the sedimentary grains as a result of dissolved minerals in groundwater precipitating (crystallizing) from water in the pore spaces and eventually cementing the sediments to create a rock.
Chemical sedimentary rocks are created when minerals precipitate from water. When dissolved substances leave water, it precipitates. Take a glass of water and add some salt (halite), for instance.
Additionally, it acts as an erosive and weathering agent, generating the grains that eventually form detrital sedimentary rock.
Therefore, materials dissolved in solutions is one source of the sediments that form sedimentary rocks.
