Answer:
(3)
Explanation:
I believe 3 would be the answer here because when interacting with a salt solution, plant cells will look like that. Hope this helped!
Diagram 3 of the cell will represents cell's appearance after being kept in 15% salt solution.
This will happen because of exosmosis in which the water will move out of the cell causing to to get shrink called plasmolysisWhat is osmosis?It is the process of movement of solvents through a semi- permeable membrane from region of lower solute concentration to higher solute concentration.
There are three types of osmosis:-
Isotonic:- The solutions bring compared have equal concentration of solutesHypotonic:- The solution with lower concentration of solutesHypertonic:- The solution with higher concentration of solutesTo know more about osmosis here

Answers
Answer:
1. Light penetration
2. Distance from shore
3. Depth of water
4. Temperature
5. Amount of nutrients/salt
Explanation:
Oceanographers use various methods to determine vertical and horizontal zones in the ocean. First and foremost are the distance from the land and the depth of the water. These contribute to the other factors, such as temperature and light penetration. They also measure how much salt or nutrients are available at that zone, which plays a role in how much life is discovered in the location.
The photic and mesopelagic zones are mainly grouped by light penetration, while mesopelagic, abyssopelagic, hadalpelagic, benthic, and bathyal zone are categorized by depth and temperature. When looking at the pelagic zone, the neritic and the oceanic sections are differentiated by the distance from the land.

Which of these graphs represents the effect of temperature on the rate of photosynthesis? Explain your answer.
WILL MARK BRAINLIEST!!
Answers
Answer: A
Explanation:
In plants and other primary producers, photosynthesis is a biological mechanism that is vital to energy production. Energy-containing carbohydrates are derived from light, water and carbon dioxide in the form of glucose molecules.
The waste product oxygen is released as a result. Photosynthesis depends on many variables, including:
carbon dioxide concentration,
ambient temperature
and light intensity
It is a rate-limited reaction. Since photons or particles of light provide the energy required for the reaction, high intensities of light increase the photosynthetic rate. From the graph shown, as the intensity increases steadily, so does the rate- but at too high of an intensity, it ceases to affect the rate of photosynthesis, which becomes constant or plateaus.
Beyond this point, either the supply of carbon dioxide or the temperature limits the reaction. For instance, at high intensities tissues may even be damaged by high temperatures or heat.
Graph A represents the effect of temperature on the rate of photosynthesis.
Why is photosynthesis affected by temperature?Photosynthesis is a biological process that is essential to the synthesis of energy in plants and other primary producers. Light, water, and carbon dioxide combine to generate glucose molecules, which are the building blocks of energy-containing carbohydrates.
As a result, the waste product oxygen is emitted. Numerous factors affect photosynthesis, such as the amount of carbon dioxide present, the surrounding temperature, and the amount of light. It is a reaction with a rate constraint. High light intensities accelerate the rate of photosynthetic reaction because photons, or light particles, supply the energy needed for the reaction. According to the graph, the rate rises steadily as the intensity does, but at a certain point, the intensity stops having an impact and the rate of photosynthesis plateaus or becomes constant.
Beyond this point, the reaction is restricted by either the temperature or the carbon dioxide supply. For instance, at high intensities, heat or high temperatures may even harm tissues.

Eliminate and explain pls
Answers
Answer:
Explanation:
A. Inorganic molecules are rarely present in the human body, and the products of photosynthesis only contain one inorganic molecule (a molecule without carbon), [tex]O_2[/tex].
B. This is correct because when looking at the photosynthesis equation you have [tex]H_2O[/tex] + [tex]CO_2[/tex] + Sunlight = [tex]C_6H_{12} O_6[/tex] + [tex]O_2[/tex] Now illustrating this conversion, the [tex]O_2[/tex] Was made from the breaking of the bonds, so no new bonding was formed, this is the only inorganic molecule. The organic molecule, glucose, or the C6H12O6, was made combining the ingredients H2O and CO2. In order to combine the components used to make the glucose, the energy from the sun helps with the exchange of electrons and facilitates the bonding to make the organic molecule glucose.
C. Sun energy can not be converted into energy used to create enzymes
