The correct answer is : Light energy is captured by plants; light energy is converted to chemical energy.
In the process of photosynthesis, special pigment molecule called chlorophyll can capture the energy of the light, more specifically the photon. When a particle of light (a photon) with a specific energy reaches this pigment in the leaves of plants, the energy is transferred from the particle to the molecule, and the molecule becomes excited. This is the phase where the energy of the light is captured and transformed into chemical energy that can later be used to make sugars.
All of the later chemical processes that transfer the energy from the excited chlorophyll to the sugar molecules are not dependent on the light and can happen during the night as well.
Answer:
A cell membrane is made of two layers.
The cell membrane is composed by a phospholipid bilayer where the interior side is hydrophobic and non-polar, while the outside is hydrophilic and polar
Pores and proteins in the cell membrane allow passage through it.
The pores and proteins in the cell membrane have several functions such as, for example, cell signaling (proteins) and selective transport (pores)
Answer: C. there is more silicon than calcium at the surface of the earth
Explanation:
The attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together. This needs to happen for a solute to dissolve in a particular solvent
.
Answer: Option A
<u>Explanation:</u>
Solute means the substances which get dissolved by another one, Ex: salt. On the other hand, Solvent refers the substance which dissolves. Ex: Water. To get dissolved in solvent, the particles present in solute move away.
It is possible only when the attractive force between solute and solvent are greater than binding force of solute and solvent. Separation and mixing up with solvent particles, in general, called as solvatation.
Weathering breaks down and loosens the surface minerals of rock. Hence, the broken rocks are transported to another place where it decomposes and forms soil. Therefore weathering is important for soil formation
