Plants can provide the materials that animals use in cellular respiration, and animals can provide some of the materials that plants use for photosynthesis. The image below shows the relationship between photosynthesis and cellular respiration. According to the diagram, how does cellular respiration aid the process of photosynthesis?
It produces ATP.
It produces glucose.
It produces mitochondria.
It produces carbon dioxide
Answer:
it produce atp
Explanation:
.............
Cellular respiration is a metabolic process that occurs in the cells of an organism. Carbon dioxide from cellular respiration aids the process of photosynthesis.
What are cellular respiration and photosynthesis?Cellular respiration is a process that takes place in the organism's cell where the cellular oxygen or chemical energy gets utilized and converted to ATP and waste like carbon dioxide.
The carbon dioxide released by the organism in the atmosphere is used by plants in the process of photosynthesis. Photosynthesis is a process that utilizes carbon and water to form glucose and oxygen.
Therefore, cellular respiration supports the process of photosynthesis by option D. producing carbon dioxide.

What is the concentration in molL-1 of 20 mL of Na2CO3 solution that neutralises 15 mL of 1 M HCl solution?
Answer:
[tex]0.75\ \text{M}[/tex]
Explanation:
[tex]C_1[/tex] = Concentration of [tex]Na_2CO_3[/tex]
[tex]C_2[/tex] = Concentration of [tex]HCl[/tex] = 1 M
[tex]V_1[/tex] = Volume of [tex]Na_2CO_3[/tex] = 20 mL
[tex]V_2[/tex] = Volume of [tex]HCl[/tex] = 15 mL
We have the relation
[tex]V_1C_1=V_2C_2\\\Rightarrow C_1=\dfrac{V_2C_2}{V_1}\\\Rightarrow C_1=\dfrac{15\times 1}{20}\\\Rightarrow C_1=0.75\ \text{M}[/tex]
The concentration of [tex]Na_2CO_3[/tex] is [tex]0.75\ \text{M}[/tex].

What is the relationship between molecular motion and energy?
Answer:
Because the particles are in motion, they will have kinetic energy. The particles will not all have the same energy, and the energy of the particles is constantly changing as they undergo changes in speed. Thus, for a given sample of matter, we can only talk about the average kinetic energy of the particles.
Explanation:
I hope this helps and pls mark me brainliest :)
We do know that if we "give" energy to a given object, the temperature of the object increases.
So there is a direct relationship between temperature and energy.
From this idea, we can conclude that:
"As we increase the energy, we also will see an increase in molecular motion."
We also do know that, as the temperature of an object increases, also does the kinetic energy of the particles that conform to the object (as the kinetic energy increases, the particles move more, this is why as we increase the temperature we usually see an increase in the volume of the object).
This increase in kinetic energy is related to the molecular motion (the movement of the electrons and nucleus o a molecule) as the kinetic energy of these parts increase, these move more.
So the relationship between molecular motion and energy is:
As we increase the energy, we also will see an increase in molecular motion.

Example #1: 0.450 mole of Fe contains how many atoms?
Answer:
Number of Fe atoms = 2.709 × 10^23 atoms.
Explanation:
Given the following data;
Number of Fe moles = 0.450 mole
We know that Avogadro constant is equal to 6.02 * 10^23 mol¯¹
Number of Fe atoms = number of Fe moles * Avogadro constant
Substituting into the equation, we have;
Number of Fe atoms = 0.450 × 6.02 * 10^23
Number of Fe atoms = 2.71 × 10^23 atoms.
Note: Fe is the symbol for the chemical element Iron.
is CdCi2 covalent or ionic
Answer:
binary and 11
Explanation:
CaCl2 or Calcium Chloride is an ionic bond and not a covalent bond. Since there should be sharing of electrons between two atoms to be a covalent bonding. In case of calcium chloride, the calcium gives up an electron to each chlorine atom, becoming Ca2+ ions and chlorine become Cl– ions.

Answer: [tex]8.38\times 10^{23}atoms[/tex] of carbon
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
mass of sugar= [tex]density\times volume=1.59g/ml\times 25ml=39.75g[/tex]
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{39.75g}{342.3g/mol}=0.116moles[/tex]
1 mole of sugar [tex]C_{12}H_{22}O_{11})[/tex] contains = [tex]12\times 6.023\times 10^{23}=72.28\times 10^{23}atoms[/tex] of carbon
0.116 mole of sugar [tex]C_{12}H_{22}O_{11})[/tex] contains = [tex]\frac{72.28\times 10^{23}}{1}\times 0.116=8.38\times 10^{23}atoms[/tex] of carbon

plzzzzzz help mee
also friction is not the answer
Answer:
Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere.
