Explanation:
Endomembrane system is basically a system or organelles and membranes in eukaryotic cells, which is involved in packaging, modifying and transporting the proteins and lipids across the cell.
Many organelles and membranes play role in this system like lysosomes, endoplasmic reticulum, Golgi bodies and nuclear membrane.
Note: Chloroplasts, Mitochondria and peroxisomes are not part of endomembrane system.
You can see figure depicting endomembrane system for better understanding.
Answer:
Explanation:
Lets say you are using the water to make noodles when you put the water on to boil the water evaporates and turns into a gas instead of a liquid (water vapor)
Answer: Marginal analysis
Explanation:
Marginal analysis is used to evaluate the marginal benefits and marginal costs of reducing pollution.
As the complexity of environmental protection grows, inexpensive and simple ways of mitigating emissions start to decrease, and more costly approaches need to be used and the marginal cost is increasing. Often, marginal benefits are reduced as environmental security increases.
As the amount of protection for the environment rises to, the marginal costs outweigh the marginal benefits. Society is not allocating resources effectively at this stage of environmental security, since so many resources are giving up to reduce emissions.
As the scope of the environmental regulation grows, additional environmental spending will likely result in increased marginal costs.
Hence, marginal analysis is a specific tool used to way the cost of benefit versus cleanup in the environment.
