This is extremely vague, but assuming this is regarding concentration gradient in the nervous system, the Sodium-Potassium pump is responsible for transporting sodium and potassium.
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.
Answer: 1 is a red blood cell and 4 is a white blood cell
Explanation: the red blood cell carries oxygen to mostly the lungs and other parts of the body and the white blood cells fight off disease in your body
The answer is round dance. The round dance communicates that a food source is nearby; it does not communicate information about the distance or direction to the food source. Waggle dance communicates information about the direction and distance to food source. In the waggle dance distance to a food source is indicated by the speed of the dance and by the number of waggles.
Answer:
A
Explanation:
All eukaryotic cells possess certain membranous organs called organnelles. One of these organnelles is the ENDOPLASMIC RETICULUM. Endoplasmic reticulum (ER) is a membranous network that forms a flattened sac in the cytoplasm. The ER in eukaryotes can be found as two types; Rough ER and Smooth ER.
The Rough and Smooth ER are both part of the endomembrane system but distinct in physical appearance as ribosomes are attached to the outer surface of the Rough ER, giving it its name. This physical distinction is responsible for their functional distinction. Rough ER functions mainly to modify proteins produced in the ribosomes attached to it while smooth ER modifies lipids.
