Answer:d
Explanation:I’m not 100% sure how to explain it but I’m almost for sure it’s d.
It would 3 because if you read it tells you the answer
B). light energy is not required to proceed
Explanation:
In the Calvin cycle of photosynthesis, light energy is not required. The Calvin cycle is light independent and it is made up of a series of redox reactions.
- During photosynthesis reactions, green plants manufacture their food using carbon dioxide, sunlight and water.
- During the Calvin cycle aspect, light energy is not required for chemical reactions to take place. The light energy helps to move electrons.
- The cycle is also known as dark reactions.
- It is at this stage that carbon dioxide combines with water to form glucose.
- The reaction is initiated with light energy which produces NADPH and ATP.
- The Calvin cycle follows by using the NADPH and ATP to produce glucose in the dark phase.

B; Seawater mixes with freshwater so the water has intermediate salinity
Explanation:
In an estuary, seawater mixes with freshwater so the water has intermediate salinity. Estuaries are usually located in transitional environments.
- Estuary is the wide part of a river where it nears the sea.
- This is called a transitional zone.
- Water from continental rivers usually fresh are brought in close contact with ocean water that is salty.
- The water here is said to be brackish as it is intermediate between salt and seawater.
- Organisms living in such terrain must be be well adapted to changing salinity.
