Answer: A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial. Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass. The biological membranes of cells are created by two sheets of phospholipid, which contain a lipid tail attached to a polar head. The tail regions of each sheet cluster together, while the heads of the molecules point outward. The polar heads point both outward toward the environment of the cell and inward toward the cytosol. In this way, a hydrophobic region of lipid tails separates the two bodies of solution. This can be seen in the image below.

Driving a car, smoking, burning of woods for heating purpose and cooking food.

Explanation:

Driving a car, smoking, burning of woods for heating purpose and cooking food are the activities that are performed in our home daily. These activities greatly affected the biogeochemical and hydrologic cycles by increasing the concentration of carbondioxide gas in the atmosphere. Burning of fossil fuels in the car engine and burning of woods releases carbondioxide gas that causes air pollution. The use of electric cars and electric heater can decrease the impact on these biogeochemical and hydrologic cycles.

Why does the cell replicate its DNA?
Verizon [17]

Explanation:

When cells asexually reproduce they split off from itself, and they have to replicate their DNA so both cells will have it because DNA is what tells the cell what to do, and how to work. The DNA will tell the cell parts all how to do their jobs, and will let the cell know when it should split off from itself. The DNA controls everything in the cell so without it the cell wouldn't know what to do.
