Cell membranes are semi-permeable. That is why they can allow only some substances to enter the cell. It basically depends on the size of the molecules. Smaller atoms like water can easily pass through. However, macromolecules such as sugars, oils and proteins cannot easily pass because they contain a long chain of monomers.

Answer:

Explanation:

Bonds form when atoms share or transfer valence electrons. In a covalent bond, two atoms share one or more electrons. Water is a polar molecule. A hydrogen bond is a relatively weak bond between two oppositely partially charged sides of two or more molecules.

What is biology terms​
Nady [450]

Answer:

Biology is the scientific study of life.[1][2][3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.[1][2][3] For instance, all living organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.[1][2][3] Finally, all living organisms require energy to move, grow, and reproduce, as well as to regulate their own internal environment.[

lozanna [386]

Answer:

The correct answer will be- Option-A

Explanation:

The Theory of Island Biogeography was proposed by the MacArthur and Wilson's in 1967 which proposed that the number of species-immigration and extinction rates are determined by the size of the island and distance of the island from the mainland.  

The suggestions made by them are:

1. The islands which remain farther from the mainland receive very few species as compared to the closest mainland.

2. Smaller island shows a high rate of species extinction as compared to the larger island.

Thus, option-A is the correct answer.
