Answer:
true
Explanation:plants require less water in times of active growth because when we give more water , the plant will rot .
Answer AND Explanation:
Bone tissue consists of an organic matrix which is impregnated with calcium salts especially phosphates and carbonates. The organic matrix confers toughness to bone while calcium salts confer hardness. Small blood vessels called haversian canals supply the bone with oxygen and nutrients. Cartilage is afirm bu flexible substance which is less rigid than bone. It consists of an organic matrix in which are embedded spherical cells called chondroblasts.
Answer:
The reason the compressed air gets cold after being used is due to a process known as adiabatic cooling, a property of thermodynamics. A gas, initially at high pressure, cools significantly when that pressure is released. The compression needed to turn a gas to liquid allows a large amount of gas to fit in a relatively small space, and when that gas is released to a large space, it rapidly expands to fill the space.
During the process of biological magnification , the concentration of pollutants, such as DDT or mercury, is multiplied as it passes up a food chain.
Answer: Option B) NADH and FADH2
Explanation:
The purpose of the Krebs cycle is to convert potential chemical energy into metabolic energy in the form of ATP that can be used by the body.
Hence, the products of the Krebs cycle include:
- 3 molecules of NADH,
- 1 molecule of FADH2,
- 1 molecule of GTP,
- 2 molecules of CO2
Thus, NADH and FADH2 are two of the products of Krebs cycle.
