Hi
1. Lithosphere
2. Hydrosphere
3.atmosphere
4. Biosphere
The lithosphere/geosphere is made of the earth's core, the mantle, crust, ocean floor,mountains, sand, etc.The hydrosphere is made of everything water such as oceans, rivers, lakes, rain, and snow.The atmosphere is made of gasses such as oxygen, and hydrogen.Finally the biosphere is all that has life such as plants, animals, people, insects, etc.
Answer:
The correct answer is allopatric speciation.
Explanation:
Allopatric speciation occurs when a geographical barrier comes between a species population living in the same area. This geographical barrier separates the population into two different geographical area which do not have the same condition.
So as both the separated population get different habitat environment to live so they evolve differently from each other. So natural selection and genetic drift works differently in both the population which brings genetic changes in the population and helps in creating a new species.
We use cell membranes to treat disease because the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.
<h3>What is the cell membrane?</h3>
The cell membrane is a thin lipoprotein film formed by phospholipids and proteins delimiting the cytoplasm of all types of cells. They prevent invading microorganisms from attaching to the cell and replicating.
Then, using the concepts of cell membrane, we can use them to prevent viral diseases from occurring since the virus cannot fix itself to replicate. So in this case, the cell membrane is one of the main barriers that pathogens need to overcome, hindering their replication.
