Why are marine oceanographers particularly concerned with coastal regions? o a. coastal regions are highly impacted by human activity. o b. previous studies in marine science have largely ignored them. o c. they are the only areas that marine oceanographers can access. o d. by definition, marine oceanographers are only concerned with the coast.

A. Coastal regions are highly impacted by human activity

Explanation:

Since I'm not completely sure I will debunk the others and let you decide.

-Option D- says they are ONLY concerned with the coast. KEY WORD only. Oceanographers study the ocean and not just the coast.

-Option C- also not true, the coast is probably the easiest portion to access but growing technologies and inventions like submarines made the ocean easier to study.

-Option B- I'm not sure of this one. I would think previous studies would start with the coast because it's the easiest to access

-Option A-  Man-made beaches, water pollution, shoreline erosion. changing an organisms environment disrupts the ecosystem and human activities cause a significant decline in coastal habitats. i think this is the answer

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

bal is blood alcohol level. bac will normally be higher in a person with more body fat. so the answer to your question would be, as body fat decreases, the increasing rate of bal decreases.
