The <u>Coast Guard</u> works with the Environmental Protection Agency to enforce marine biology regulations along the coast and in the Great Lakes channels.
Answer: Option A
<u>Explanation:</u>
The Environmental Protection Agency (EPA) takes initiative to instill certain regulations to maintain the Ocean and its resources with the help of coastal guards and NGO’s. The Ocean coast is polluted due to various avoidable and unavoidable pollutants like oil leakage, industries letting in their waste, ship wrecks etc.
President Richard Nixon was the one who created this EPA. The EPA takes utmost care by educating the people of the necessity to maintain the coast in a disciplined attitude so as to have a pollution free oceanic coast which would in turn not adhere into the relevant working stream. Avoiding litter is the main rule that has been imposed.

Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.
Integrins are the main principal receptors used by the cells of  animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

Choices 1, 2, and 3 all emit carbon dioxide, not enough to destroy the planet, but they still can cause it over a large amount of time, due to Carbon Dioxide being a greenhouse gas. Therefore, the answer is 4. Bicycles do NOT emit any carbon dioxide at all.
