Answer:
It's Substrate.
Explanation:
Substrates are small molecules.
Answer:
The correct answer is option A. "Line spectra".
Explanation:
Line spectra is a method that is used to determine the temperature of a star. Line spectra is based on the principle that, depending on the temperature of a star, a line is traced which is compared to the continuum temperature that could either generate a emission (hotter) or absorption (colder) line. A spectrum of lines depending on the temperature have been established under the code OBAFGKM, where O is the hottest an M is coldest.
B. tiny algae and plankton decomposed under conditions of heat, pressure, and low oxygen.
Explanation:
Oil is most likely to form where tiny algae and plankton decomposed under conditions of heat, pressure and low oxygen.
Coal will form when plant materials like twigs, leaves and tree trunks decomposed under conditions of heat, pressure and low oxygen.
- To form oil, algae and plankton will be gathered with sediments in a basin.
- Rapid burial causes the algae and plankton to be cut off from aerobic environment that would lead to the decay of these organisms.
- They are buried alive and as the basin subsides, temperature and pressure acts to produce kerogen.
- Further cracking produces oil and gas.
