<h3>Chain of electron transfer The electron transport chain is the final stage of the respiration route, and it is where the most ATP molecules are produced. The electron transport chain is a group of proteins located on mitochondria's inner membrane. The hydrogen ions and electrons are released into the transport chain by NADH.</h3>
An electron transport chain (ETC) is a collection of protein complexes and other molecules that transfer electrons from electron donors to electron acceptors via redox reactions (both reduction and oxidation occur at the same time) and couple this electron transfer with proton (H+ ion) transfer across a membrane. The electron transport chain contains many membrane-bound enzymes.
Answer:
12 billion years and beyond
Explanation:
Answer:
D
Explanation:
<em>The correct answer would be heredity.</em>
Heredity is one of the major attributes of living organisms. <u>It is a biological process that involves the transfer of traits or genetic characteristics from one generation to another. </u>WIthout heredity, living organisms will not be able to pass attributes to their offspring and the latter will have no connection to the former generations whatsoever.
<em>Correct option: </em><em>D</em>
Wetlands include swamps, marshes, bogs, riverbanks, mangroves, floodplains, rice fields—and anywhere else, according to the U.S. Environmental Protection Agency (EPA), that saturation with water is the dominant factor determining the nature of soil development and the types of plant and animal communities there. They are widespread in every country and on every continent except Antarctica. If all the world’s wetlands were put together, they would take up an area one-third larger than the United States.
Environmentalists, biologists and others concerned about the health of the planet and its inhabitants recognize the key role wetlands play in life on Earth. The EPA points out that, besides containing a disproportionately high number of plant and animal species compared to other land forms, wetlands serve a variety of ecological services including feeding downstream waters, trapping floodwaters, recharging groundwater supplies, removing pollution and providing fish and wildlife habitat. Wetlands can also be key drivers of local economies, given their importance to agriculture, recreation and fishing.
