give two effects of photolysis of water during light-dependant reaction
Spliting of water and production of oxygen are the two effects of photolysis of water during light-dependant reaction.
What are the effects of photolysis of water during light-dependant reaction?Photolysis refers to the use of light energy in order to split water molecules and produce oxygen. In the light-dependent reactions, light energy is absorbed by chlorophyll and transferred to the reaction center of photosystem II.
So we can conclude that Spliting of water and production of oxygen are the two effects of photolysis of water during light-dependant reaction

In which of the following situations does the cell use active transport?
Answer: The correct option is B. Sodium ions move into the cell from areas of lower concentrations.
Explanation:
Active transport can be described as a process in which molecules move from an area of lower concentration to an area of higher concentration against the concentration gradient. Energy is required for the process of active transport to occur.In the option B, sodium ions are moving into the cell from areas which have a low concentration of sodium i.e against the concentration gradient. Hence, option B tells that the sodium ions will move inside the cell by the process of active transport.

An investigation involving osmosis and plant cells was performed by a group of students. Sweet potatoes were used as
the source of plant cells in the experiment. A sweet potato was diced into evenly sized andshaped cubes and placed
in beakers containing various glucose concentrations. The experimental setup is shown in the table here.
Which statements accurately predict the beaker in which water will enter the cells at a greater rate, causing an
Increase in mass for the sweet potato cells?
A)
Beaker 1
B)
Beaker 3
C) beaker 4
Answer:
A
Explanation:
Water will enter and leave the cells at the same rate via osmosis
The correct option is (A) Beaker 1 in which water will enter the cells at a greater rate, causing an increase in mass for the sweet potato cells.
What is Osmosis?Osmosis refers to a process in which the water or solvent diffuse across a semipermeable membrane (here cell membrane) from the area of high solute (here glucose) concentration to low solute concentration. The concentration of glucose in the water of beaker 1 is 1.5M which is highest as compared to other beakers.
The concentration of glucose solution in beaker 1 is hypertonic to the concentration of glucose in the cell which makes the water to move inside the cell via osmosis. Movement of water inside the cell results in increase in mass for the (sweet potato) cells.
Thus, the water will enter the cells at a greater rate in the beaker 1 because the glucose concentration is highest in the beaker 1 corresponding to its cell glucose concentration.

Salt is most likely to be mined using which mining technique?
A.) Mountaintop removal
B.) Solution mining
C.) Placer mining
D.) dredging
Answer:
B.) Solution Mining
Explanation:
Definintion: solution mining is mining of underground, water-soluble minerals, usually using one or more drilled wells to dissolve the minerals with water.
Sorry if it's wrong!
=> Solution mining is done by pumping water into subterranean salt deposits, found in many parts of the world, dissolving the salts and pumping the brine to the surface for drying and further use.
