Answer:
In algae or any other photosynthetic organism, there is the internalization of carbon dioxide gas in the reaction with water in the presence of sunlight to produce sugar molecules and oxygen gas in the atmosphere. So, photosynthesis is the process that releases or produces oxygen gas.
In cellular respiration (aerobic) the product of photosynthesis, glucose molecules, and oxygen react to produce the energy and releases carbon dioxide and water as byproducts.
The given question is incomplete, it lacks the diagrams (choices), however, the correct choices are attached as image:
The diagrams accurately represent the use of gases in both cellular respiration and photosynthesis is - diagram d. (check image)
CELLULAR RESPIRATION:
is the process in which living organisms obtain energy (ATP) by breaking down food molecules in their cells. It combines glucose and oxygen to produce carbon dioxide (CO2) and water (H2O) as follows: C6H12O6 + 6O2 = 6CO2 + 6H2OPHOTOSYNTHESIS
is the process in which green plants manufacture their own food using energy from sunlight. It combines carbon dioxide (CO2) and water (H2O) to produce glucose and oxygen (O2) as follows:6CO2 + 6H2O = C6H12O6 + 6O2
Thus, The correct choice of the diagram is - diagram d.

two?
A As Earth orbits around the Sun, the axis changes its amount of tilt, which causes a change in
the amount of sunlight reaching Earth.
B Eastern and western hemispheres each experience a different season when Earth is at each
position shown and when it is 14 and 34 around its orbit.
C Halfway between the positions shown, the amount of solar energy received is less than when
the axis is pointed toward the Sun, but more than when the axis is pointed away from the
Sun.
D When Earth is 14 and 3/4 around its orbit, the northern hemisphere points directly at the Sun.

what is the characteristics of solid
Answer:
they have there own shape that is not manipulated and they are typically hard
Explanation:
In a chemical reaction, if one knows the mass of A, one could determine:
1) the mass of any other reactant and product
2) only the mass of B
3) only the mass of C
4) only the mass of A
If one knows the mass of A, they may calculate the mass of any other reactant and product in a chemical reaction.
How can the mass relationship in a chemical reaction be determined?Find out how many moles each reactant has. To identify which reactant is limiting, compare the mole ratios of the reactants with the ratio in the balanced chemical equation. Determine how many moles of the limiting reactant can be converted into the product.
When the mass of the limiting reactant is known, how does one calculate the mass of the product?Calculate the maximum number of moles of product that can be produced from the limiting reactant using mole ratios. Add the product's molar mass to the number of moles.

A valley or depression between continents
A. Ocean Ocean basin.
B. Divergent boundary
C. Transform boundary.
D. Convergent boundary
A valley or depression between continents is called Ocean basin. Therefore, the correct option is option A.
What is valley?A valley is indeed a long, low region that commonly runs between mountains or hills and has a river and stream that runs through one end to another. Most valleys are produced through long-term erosion of the ground surface by streams or rivers. Some valleys are produced by glacial ice erosion.
These glaciers may persist in valleys in mountainous areas or in polar regions. These glacially produced valleys could have been constructed or extended during ice periods at lower latitudes or elevations, but they are currently ice-free and populated by rivers or streams. A valley or depression between continents is called Ocean basin.
Therefore, the correct option is option A.

A tree leaf appears to be green. Which statement explains why the leaf isn't a
blackbody radiator?
A. The leaf reflects light and does not emit it.
B. The leaf does not change temperature when it reflects light.
C. The leaf emits light but does not reflect it.
D. The leaf emits only blue and yellow light.
Answer: A- Like the comments in the other one,the answer is A.
Explanation: Leaves don't emit visible light.
The statement that explains why the leaf isn't a blackbody radiator is the leaf reflects light and does not omit it. The correct option is A.
What is a blackbody radiator?A blackbody radiator is an object that absorbs all the electromagnetic radiation, of any wavelength and coming from any direction. This object does not emit any light to it. According to law, the good absorber is one who is also a good emitter.
The tree leaf is not a blackbody radiator, because it absorbs only green light and other lights are emitted by it, that's why it appears green. Whereas a blackbody radiator does not emit any amount of light even if the temperature will be increased.
Thus, the correct option is A. The leaf reflects light and does not omit it.
