Answer:
Explanation:
Tidal power can be harnesed and be used to drive turbines which are used in hydroelectric power stations. Tide involves the movement of water from one place to another and this results in ocean currents. The tides carry a huge amount of renewable energy in them.
Wave power: waves accompany tides. These waves can be easily harnessed to drive wind turbines which in turn produces electricity. They can also be used in wind mills.
Power from fossil fuels: Oceans contain a vast reserve of fossil fuels. Most oceans in times past are sedimentary basins that accumulates remain of organisms. As natural processes plays out, they yield fossil fuels. These fossil fuels can be tapped for use in different machines and gas power plants.
According to the research, the functions of the skin are to protect the body, helps the body cool down and it collects information from the surroundings.
<h3>What is the skin?</h3>
It is the border of the organism with the external environment that is made up of three main layers: epidermis, dermis and subcutaneous tissue.
Its function is the isolation and protection of the body against external aggressions, changes in temperature, adaptation and the connection of the individual with the surroundings.
Therefore, we can conclude that according to the research, the functions of the skin are to protect the body, helps the body cool down and it collects information from the surroundings.

Answer:
The preferable words for the fill in the blanks will be -
Aragonite, calcite
Explanation:
- Biogenic minerals are minerals produced by living organisms. Two commonly seen biogenic minerals are <u>aragonite</u>, which is often produced by coral and other invertebrates, and <u>calcite</u>, which often makes up the shell material of mollusks such as clams.
- Biogenic minerals are the mineral substances that are produced by geologic processes. For living organisms, it is their most commonly produced byproduct.
- E.g; vertebral bones, shells of Oyster, mussel, and clam (aragonite), etc.
Phototropism plants the most
Answer:
Climatic variation
Explanation:
Climatic variation lead to formation of annual rings in the activity of cambium because In climates with alternations of either cold or dry seasons, the growth cells or cambium of wood stems produced when water is available and growth is rapid are always large and have thinner walls and where the climates is dry, the growth is slower and the cambium produced short and thicker walls but where there is uniform climate, there won't be much different as the growth will be uniform.
The cambium is responsible for secondary growth of root and stem.
