Answer:
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. ... Translation occurs at the ribosome, which consists of rRNA and proteins. In translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome.
Answer:
A) True
The polarity of water is what makes it an ideal transport vehicle for nutrients and micronutrients that are water-soluble. Within organisms, water can be used to transport nutrients and even waste from one part of the body to the other. In the case of humans, urine is used to get rid of soluble waste from within the body.
B) True
During the process of photosynthesis, carbon dioxide (CO2) and water (H2O) are taken from the air and soil respectively. Oxygen is able to produce water when it is reduced. Hydrogen during this process is oxidized.
C) False
Ice floats on water. Hence it cannot be denser than water. Rather, water is denser than Ice. Because of the structure of hydrogen bonds, when they are iced, the bonds tend to pull apart, thus making ice expand somewhat. This expansion creates microscopic pockets of air in the molecules thus given them buoyancy.
D) True (X)
E) True (X)
F) True
Heat Capacity refers to the amount of heat a substance like water can absorb before it's temperature rises by 1 degree. This property is important, because, were it not for the high specific heat capacity of water, many people and plants would have boiled over.
G True (X)
Heat of vaporization is the kind and amount of energy required to alter one gram of liquid into a gas at boiling point

Answer:
The formula for calculating magnification is:
Magnification = Size of drawing / Actual size
Size of drawing = 40 mm
Actual size = 40 micron meter
Convert 40 mm to micron unit: 40 * 1000 = 40,000 micron
Magnification = 40,000 / 40 = 1000.
The magnification is 1000 X.
This answer means that the drawing is 1000 times bigger than the actual size of the cell.
