<span>A cell is the most basic form of life. It is what most of the organisms are made off. For the organism to function, the cell must also function. It has organelles too that helps functions what the microorganisms need. A leaf cell contains chloroplasts that animal cells and animal cells do not have. The chloroplast is where the photosynthesis happens. It needs sunlight for the process of photosynthesis. Notice that the leaf has a broader surface area to enable them to be exposed to the sun.</span>

How is acid rain formed list and describe 2 human activities that can alter pH levels of rain?

ICE Princess25 [194]

Answer:

Have a great day!

Explanation:

Human activities are the main cause of acid rain. Over the past few decades, humans have released so many different chemicals into the air that they have changed the mix of gases in the atmosphere. ... In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air.

Rotting vegetation and erupting volcanoes release some chemicals that can cause acid rain, but most acid rain is a product of human activities. The biggest sources are coal-burning power plants, factories, and automobiles.

Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

The solutions in the arms of a U-tube are separated at the bottom of the tube by a selectively permeable membrane. The membrane

Leviafan [203]

Answer:

Option D

Explanation:

It is given that the permeable membrane at the base of the tube is permeable to NaCl solution but is not permeable to glucose.

Thus, sodium chloride from the arm of tube with high NaCl concentration will start moving towards the arm with low NaCl concentration and hence, the salt concentration will reduce on side A.

The volume will not remain constant as the concentration of NaCl on side A will reduce thereby decreasing the water level from its initial mark

Hence, option D is correct
