Pls answer ill give brainlyist (ik i spelt it wrong)
Margaret [11]

Answer:

Lower Salinity in the ocean water.

Explanation:

The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.

Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.

As temperature increases, the space between water molecules increases—also known as density, which therefore decreases. ... Salinity and density share a positive relationship. As density increases, the amount of salts in the water—also known as salinity, increases

What is the approximate percentage of total fixed nitrogen attributed to human activities?
Sever21 [200]

Of the annual global total of fixed nitrogen, human activities account for roughly 45%.

Nitrogen fixation is the global amount of nitrogen that gets assimilated by any living organism into another organic compound. The organic compound can be ammonia or nitrogen ions.

Of the total global annual nitrogen fixation, humans account for a great amount. The current estimation is that humans cause 45% of the nitrogen fixation annually. The leading causes of this high rate are the burning of fossil fuels and increased agricultural fertilizer use.

describe the similarities and differences between aerobic cellular respiration and anaerobic cellular respiration
Lena [83]

Aerobic cellular respiration takes place in the presence of oxygen and anaerobic cellular respiration takes place in the absence of oxygen.

Similarities:

  • As a beginning molecule, glucose is used in both aerobic and anaerobic respiration, which is a similarity. The substrate is what you see here.
  • Additionally, both aerobic and anaerobic respiration results in the production of ATP, but aerobic respiration generates far more ATP than anaerobic respiration.
  • In both situations, food is oxidized and energy is liberated.

Differences:

  • Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen.
  • Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration.
  • Compared to anaerobic respiration, aerobic respiration produces more energy.
