How does carbon content relate to coal rank?

Biology
1 answer:
Ivan4 years ago
4 0
Coal rank is a measure of coal maturity and is the most fundamental parameter that relates both to the coalification history and the utilisation potential of a coal. As the rank increases, the vitrinite reflectance, carbon content, and C/H ratio of coal increase, while the coal volatile matter decreases.

What product of the light-dependent processes of photosynthesis is needed by the light-independent processes
Iteru [2.4K]

Answer:

ATP and NADPH.

Explanation:

The light-dependent reactions convert light energy into chemical energy. The goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then used in the light-independent reactions.

In 2016, Sub-Saharan Africa had a doubling time of 23.3 years.
Masja [62]

The correct answer is Option B: 3%.

In 2016, Sub-Saharan Africa, doubling time is 23.3 years, thus Growth rate is 3%.

<h3>What is doubling time?</h3>
  • The doubling time is the time taken by a population to double in its size.
  • This concept is applied to population growth, inflation, resource extraction, consumption of goods, the volume of malignant tumors, and many other things that tend to grow over time.
  • There is an important relationship between the percent growth rate and its doubling time known as “the rule of 70”: to estimate the doubling time for a steadily growing quantity, simply divide the number 70 by the percentage growth rate.
  • Therefore, Growth rate is 70 divided by doubling time (70/ doubling time).
  • Here, Doubling time= 23.3 years.
  • Growth rate= 70/23.3= 3%
