Answer:
Explanation:
A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited (usually a planet such as the Earth, but possibly another body such as the Moon or Sun) on each revolution. It therefore has an inclination of (or very close to) 90 degrees to the body's equator.
Answer:
The correct answers are 2.23 * 10^8 CFU/ml and 2 colonies.
Explanation:
Based on the given information, 0.1 ml is the amount of bacterial culture plated, 10^-5 is the dilution factor and the number of bacterial colonies produced is 223.
A) 223 is the number of colonies produced when 0.1 ml of the culture is plated. Therefore, the number of colonies produced when 1 milliliter of bacterial culture plated us (223/0.1)*1 = 2230
The calculation of the CFU/ml is done by using the formula,
CFU/ml = Number of colonies per ml plated / dilution factor
Thus, 2230/10^-5
= 2230 * 10^5 or 2.23 * 10^8 CFU/ml
B) The number of colonies, which would grow on a plate, which is inoculated with 0.1 ml volume of 10^-7 dilution from the similar bacterial stock will be calculated as,
CFU/ml = Number of colonies per ml plated/ dilution * volume plated.
2.23 * 10^8 CFU/ml = Number of colonies per ml plated / 10^-7 * 0.1
Number of colonies per ml plated = 2.23 * 10^8 * 0.1 / 10^7 = 2.23 or 2 colonies.
D) Plants below the surface receive less sunlight than those on the surface
Answer:
DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-m-RNA molecule, which is then processed to form mature m-RNA.

Answer:
Glycerol-induced hyperhydration will increase osmotic pressure in the body fluids and thus, decrease plasma volume
Explanation:
Glycerol is a metabolite that can be synthesized in the body from glucose and can also be obtained as a food additive. From a biochemistry point of view, glycerol plays a major role with regard to the deprivation of glucose both in aerobic and anaerobic conditions. Athletes use glycerol to delay fluid loss and avoid dehydration during exercise. This metabolite is known to attract water so it stays in the body longer, increasing osmotic pressure and decreasing plasma volume. Glycerol is also used to lose weight and improve exercise performance. Moreover, it is important to note that it has been shown that intravenous injection of glycerol may damage red blood cells (hemolysis).
