Answer:
A hot ball of gas that produces energy by combining atoms into heavier atoms.
Explanation:
A star is a huge glowing ball of hot gas, mainly hydrogen and helium. Stars fuse atoms in their core to produce heat and light energy. An example of a star is the sun, which slams hydrogen atoms together under high heat and pressure resulting in a much heavier atom, a helium atom. Very heavy elements are made in massive starts when they die.
Answer:
C
Explanation:
The rain forest zone contains an abundance of plant species available for pharmaceutical research and attempt at the synthesis of new drug compounds. The abundance of rainfall helps these many plant species to thrive and are available for use in the development of new drugs.
Answer:
true , only 50 percent organisms extinct each year
Answer:
A. Geology
B. Computer aided designs
C. Dead organisms in the oceans
D. Helps in converting dead organisms into oil and gas
Explanation:
The oil and natural gas are buried under layers and this requires a good knowledge of "geology". Furthermore, equipments must be built to explore this oil and natural gas
Involvement of Technology has to do with "Computer aided models" being generated. Seismic surveys and satellites used to collect data.
Oil and gas began as dead plants and animals living in the ocean millions of years ago.
Role of sedimentation: the Organisms in the ocean died and went to the bottom of the ocean, where a layer of sediment would cover them. Over the years, alternating layers of dead organisms and sediments were formed. As the layers bottled up, the immense pressure and heat converted the dead organisms into oil and natural gas.
