The answer is A. This ensures that the resource has enough time to regenerate so as to sustain consumption. An example is that of the carrying capacity of a habitat. If a herd of cows exceed the carrying capacity of the grazeland, the grass will be depleted and the area will be predisposed to desertification. The environment will not be able to sustain the cows anymore until the herd number reduce.
Answer:
Yes, it is
Explanation:
It is very much analogous. Just as in the analogy explained, DNA isn't visible to the naked eye when it is alone or single, or just one. On the other hand, it is very much easier to see when the DNA are in a cluster, just like in the cotton example.
Succinctly put, the example is analogous to DNA extraction
I would say either A or B
Answer:
If a rock has a volume of 2 cm³ and a mass of 12 gr, its density will be 6 gr/cm³.
Explanation:
Density is a parameter used in chemistry and physics, which relates the mass and volume of a solid or compound, establishing the amount of volume that occupies a given mass.
If we observe the density formula, we can see that the greater the mass, the greater the density, while the volume is inversely proportional, so the lower the volume, the greater the density. This formula is:
ρ = m/V
Therefore, according to the mass and volume of the rock
ρ = 12 grs / 2 cm³
<em>ρ = 6 grs/cm³
</em>
Being the density of the rock equal to 6 gr/cm³.
