Answer: The correct answer is Kreb cycle.
Cellular respiration is defined as the oxidation of food into CO₂ ( cabon dioxide) and H₂O ( water) in order to produce energy in the form of ATP ( adenosine triphosphate).
It occurs in three stages that is Glycolysis, Kreb cycle, and Electron transport chain.
Kreb cycle occurs in the matrix of the mitochondria. It includes the oxidation of a two carbon compound that is Acetyl- CoA in order to generate a pool of chemical energy in the form of ATP, NADH, FADH₂.
On the contrary, glycolysis and fermentation occur in the cytoplasm.
Thus, mitochondria is host to Kreb Cycle of the cellular respiration.
Answer:
The correct answer will be option- B.
Explanation:
Synovial fluid is a clear slippery fluid which is present in the synovial cavity.
The synovial fluid helps the nourishment as it provides nutrients to the and oxygen to the hyaline cartilage of the bones as well as the lubrication of the cartilage surfaces due to the viscous nature like oil which lubricates the piston.
This smooth surface facilitates the smooth and painless movements between the bones, therefore, the Option-B is the correct answer.
Answer:
The moon is about one-fourth the size of Earth.
Explanation:
- The Moon has a diameter of 3,476 km and is one-fourth of the size of the earth. Moon is about 27% lesser than the size of the earth.
- Earth's moon is the fifth largest moon in the solar system having a radius of 1,737 km.
- The surface area covered by the moon is about 37.9 mn km square. It is even smaller than the continent of Asia. The moon's mass is about 1.2% of the mass of the earth.
The answer is B, sameness
