(D) Most of the best sites are inaccessible by land transportation, so making roads to them is often prohibitively expensive.
<h3>What is a Reserve?</h3>
A nature reserve, also referred to as a wildlife refuge, a wildlife sanctuary, a biosphere reserve or bioreserve, a natural or nature preserve, or a nature conservation area, is a protected area that is important for its flora, fauna, or features of geological or other special interest. It is reserved and managed for conservation efforts as well as to offer unique opportunities for study and research.
In some nations, government agencies may designate them, as well as private landowners like charities and research facilities. Depending on the level of protection provided by local regulations, nature reserves are classified into various IUCN categories. It is typically subject to stricter protection than a natural park. In laws and official documents, different jurisdictions may use different wording, such as ecological protection area or private protected area.

Answer:
Ocean Engineering what they do all day? It's a multidisciplinary engineering field aimed at solving engineering problems related to the ocean environment, where engineers help oceanographers wisely explore the many vast oceans. They design and build structures, equipment and instruments that help advance marine science.

I believe the answer is 20 feet. According to McBurney and Collings, the average threshold of human hearing is the tick of a watch from 20 feet in very quiet condition.
The human hearing range is a description of the pitches and loudness levels a person can hear before feeling discomfort. There is a variety of sounds in our environment, ranging from faint sounds like birdsong and rustling leaves to louder sounds like music, yelling, and industrial noise.
During the electron transport, chan energy stored in electrons is used to pump hydrogen protons from the mitochondrial matrix to the intermembrane space. The numbers of protons increase this creates a chemical gradient(because there is a higher concentration of ions) and an electrical gradient(because the intermembrane space becomes more positive than the matrix because of the protons-H⁺). Those protons need to flow towards the matrix for equilibrium to occur. As we know the inside membrane of the mitochondria has a reduced permeability. The main place where protons can diffuse is the ATP-synthase(a protein that turns ADP and inorganic phosphate into ATP). When protons pass through they release the energy necessary for this reaction to occur(ADP+H₃PO₄-->ATP+H₂O)
