A.
The pressure of the water is decreased
B.
The pressure of the water is increased
C.
The salinity of the water is increased.
D.
The salinity of the water is decreased
Answers
The salinity of the water is increased does the flow of weathered and dissolved rock material towards the ocean affect the chemical composition of the ocean. So, the correct option is C.
What is the Chemical composition of Ocean?Understanding the chemical properties of the ocean is essential because the marine environment supports the greatest abundance of life on Earth, whose life is largely composed of the same chemicals that make up seawater and salts.
The two important elements in sea water, after oxygen and hydrogen, are sodium and chloride where sodium and chloride combine to form the salt we know as table salt. The salinity of sea water is expressed as the ratio of salt (in grams) to liters of water.
Thus, the salinity of the water is increased does the flow of weathered and dissolved rock material towards the ocean affect the chemical composition of the ocean. So, the correct option is C.

C. More green color is produced.
D. Green leaves turn red.
Answers
Answer:B. Sugar are produced
Explanation: when green leaves absorb sunlight it is converted to Energy by photosynthesis.
Answer:
I'm pretty sure it's C.
Explanation:
Plants don't get to warm unless they don't have oxygen, sugars are produced, but only during all of photosynthesis, and green leaves don't turn red unless the season is changing. But sun light gives chlorophyll what it needs to produce that green color. Therefor, C is your answer.

What is the meandering of a river?A meandering stream has a single channel that snakes through its valley, so the distance 'as the stream flows' is greater than the distance 'as the crow flies.' The outer edge of the water moves faster than the inner as it flows around these curves.Meanders form as a result of both deposition and erosion, and they gradually migrate downstream. Because of the decreased friction, the force of the water erodes and undercuts the river bank on the outside of the bend, where the water flow has the most energy.To learn more about : Meanders

What happens during the process of nitrogen
fixation?
A. Bacteria change ammonium into nitrate.
B. Bacteria grow on nodules on plant roots.
C. Bacteria convert gaseous nitrogen into
ammonia.
D. Bacteria absorb ammonia and excrete
ammonium.
Answers
Answer:
I'm not 100% sure but i think its A; let me know if this is correct.Explanation:
C. Bacteria convert gaseous nitrogen into ammonia during the process of nitrogen fixation.
What is nitrogen fixation?Nitrogen fixation is the process by which atmospheric nitrogen (N2) is converted into ammonia (NH3), which can then be used by plants and other organisms as a source of nitrogen for growth and reproduction.
This process is performed by specialized bacteria, such as those found in the nodules of leguminous plants, as well as other bacteria found in soil and water. The conversion of N2 into NH3 is an energy-intensive process, which is why nitrogen fixation is performed by only a few types of bacteria. The ammonia produced by nitrogen-fixing bacteria can be used directly by plants and other organisms, or it can be converted into other forms of nitrogen, such as nitrates and nitrites, which are also usable by plants.
