The main property of water that helps sustain life on earth is that water has. a high specific heat. This causes water to gain heat very slowly.
Specific heat is the amount of heat required to raise the temperature of water by one degree Celsius. Specific heat of water is 4, 186 joules /gram Celsius, and it is higher than that of a metal and of any other common substance.
Due to this, water resists tendency to evaporate or to vaporize and therefore plays the crucial role of stabilizing temperatures on earth for terrestrial life and at the same time enabling aquatic organisms to maintain relatively constant internal temperatures.
Answer:
If four samples have the same volume, the sample with the highest mass will have the highest density, i.e. sample Z.
Explanation:
The density expresses the amount of mass that occupies a given volume, and knowing the mass and volume of a solid, the density can be determined by the formula:
<em> ρ = m/V
</em>
From this formula it can be determined that <u>density is directly proportional to mass and inversely proportional to volume</u>.
Of the four samples, the highest mass is in the sample Z (312), so this sample has the highest density.
The answer would be C.
The sample should represent the whole population not just a small part of the population.
Answer:
it is D
Because the DNA have all our genetical storage
