Answer: Option(b)

Explanation:

The reason for including the 3 percent of freshwater as most useful in the importance of freshwater ecosystems is, almost 70 percent of earth`s surface  is occupied by water. In that only 3 percent is freshwater.

Out of  overall value 2 percent of freshwater is held up in glaciers and formed as ice at both poles of North and South. The 1 percent remaining is mostly groundwater, fills the world's aquatic ecosystems like lakes and rivers, ponds, streams, springs,, and wetlands .

zhenek [66]

Answer:

Lipid bilayer

Explanation:

Red blood cell is surrounded by a cell membrane that separates its interior from the surrounding medium. The cell membrane is a lipid bilayer and consists of two layers of phospholipids. The polar heads of phospholipids make the surfaces of the cell membrane while their nonpolar tails are buried in its core.

The snake venom has phospholipase enzymes that digest the phospholipids into fatty acids. Digestion of phospholipids of the lipid bilayer of red blood cells would cause leakage of their content into the surroundings and loss of integrity of cells.

How does industrial agriculture promote farming techniques that are ecologically destructive?
Tcecarenko [31]

Industrial agriculture promote farming techniques that are ecologically destructive by using fertilizers and using processed feeds to feed the animals. Fertilizers contain harmful chemicals that may not be seen on the plants since its main function is to kill the pests that eats the plants. What makes it destructive is when the particles of the fertilizer is mixed with water and then leached into the soil into the water table. The once pure water table is now contaminated. The accumulation of various chemicals from the pesticide can cause the death of aquamarine life and even humans. Also, it can destroy the components of the soil overtime because it can interact with other compounds found in the soil to create a harmful product.
