Answer:
Lightning can be best described as an electrical discharge, which is caused by the imbalances between the clouds and the storm and the ground or sometime within the cloud. It carries around 20,000 to 30,000 ampere of current when it comes to the ground.
It is not only the direct hit of the lightning that make you worry, but any strike that is close to us can be dangerous to us as it results in the release of huge amount of electricity in the surrounding area.
i would have to go with A.
your Ph level in the blood stays the same no matter what because it is a buffer, and the risein temperature doe not allow ANY reproduction of ANY invasions because it causes an unfavorable habitat for these invading cells to reproduce or even multiply.

Answer:
Plant and animal cells.
Explanation:
Found in every eukaryotic cell.
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.
Hope this helped!
