Answer:
$180, $360. The complete question is attached in the picture below
Explanation:
Total amount required to reduce three units of emissions by firm 1 = Sum of marginal costs from 0-3units required.
= $60 + $50 + $40 + $30 = $180
For firm 2, Sum of marginal costs for 0-3units emissions reduction
= $120 + $100 + $80 + $60 = $360
I think the government should have a plan or procedure in place to deal with the movement of the continents so as to curb species extinction.
<h3>What is Climate?</h3>
This is referred to as the atmospheric condition of a place for a long period of time.
Drifting of continents leads to a new climate being present which will affect life forms. If they are unable to adapt they may all die out and go extinct thereby disrupting the ecosystem which is why a plan should be put in place.

Answer: The structure of cell membrane is semi-permeable which allows it to pass only certain molecules.
Explanation:
The phospholipid bilayer includes phospholipids that are tightly packed. This membrane is semi-permeable in nature and it can be said that it is selectively permeable. Across this the small, nonpolar materials can pass through as lipid tails of the membrane are nonpolar in nature. Examples of the molecules that can pass through the lipid bilayer are oxygen, carbon dioxide, and others. But the water soluble molecules need assistance of nonpolar molecules to pass through it like glucose, and amino acids as they are oppose by the hydrophobic tails.
