The correct answer is option a. true.
The fossil fuels, including coal and oil are present very deep inside the earth. In the carbon cycle, only fixation of atmospheric carbon dioxide in the organic material takes place. This cycle does not involve the recycling of the fossil fuels.
The burning of the fossil fuels directly release carbon dioxide and other carbon compound in the atmosphere, which was not involved in the cycle when it was present deep beneath the earth and ocean. Hence, the burning of fossil fuels increases the amount of carbon in the carbon cycle.
Answer:
Option (b).
Explanation:
The frequency of alleles K and k in population are 0.6 and 0.4. The inbreeding coefficient is 0.3.
The heterozygote frequency can be calculated by the formula:
F =
Here, K = 0.6, k= 0.4, F = 0.3 and H = approximate genotypic frequency of heterozygote Kk.
Put the values in the above formula
0.3 =
H = 0.36 ≈ 0.34.
Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.
Hence, the correct answer is option (b).
Monosaccharides- Honey, Apples, and Kiwi
Disaccharides- Any foods with Lactose or Maltose like milk
Answer:
decreases a plant’s weight
Explanation:
Aerobic respiration is a process of respiration in which oxygen is required and the byproducts of aerobic respiration are carbon dioxide, water and energy.
Plants undergo aerobic respiration and it is a catabolic process in which complex compounds in plants turns into simpler compounds. This process reduces the dry weight of the plants.
Glycolysis is the first step in both aerobic and anaerobic respiration so it is not a typical aerobic respiration.
Hence, the correct answer is "decreases a plant’s weight".
