How can a membrane be permeable to one substance while being impermeable to another substance?

Biology

statuscvo [17]3 years ago

Answer:

It varies due to their polarities.

Explanation:

Remember, a membrane is a semi-permeable membrane. There are some substances that can cross the membrane and others have to take different route. It all comes down to their polarity. If we were to examine a membrane made of phospholipid bilayers, one side of it has hydrophilic heads and the inside has hydrophobic tails. The membrane is therefore polar, allowing polar substances to enter in and out of the cell. Non polar substances, such as water have to take a different route, through special proteins called aquaporins.

As solar energy interacts with carbon dioxide, water vapor, and several other gases in the troposphere, it warms the troposphere
Veronika [31]

As solar energy interacts with carbon dioxide, water vapor, and several other gases in the troposphere, it warms the troposphere process known as the Green house effect.

  • Troposphere is the lower most part of the earth's atmosphere comprises of Nitrogen, Oxygen, Argon, Carbon dioxide and Water vapour.
  • Carbondioxide, water vapour and other gases like methane are concentrated highly in the Trophosphere due to some human activities (Industrial revolution).
  • Such excess Green house gases forms a shield layer which retains the heat by trapping the long wave radiation of solar energy in troposphere. As a result, global warming and abnormal weather conditions occurs in the planet.
