Explanation:
When going to an interview you never want to be too early or late at all. If his car breaks down he might be angry or frustrated. I’ve never met a person who becomes happy when something bad happens.
Hopefully this helps!
Answer:
Symbiotic relationship
Explanation:
An average human body between 20 to 30 year of age with a weight of 74 kg and 170 cm contains about 30 trillion cells. The number of bacterial cells in the same man counts for about 39 trillion that is higher than the cell of the body.
The ratio between the bacterial cell to the human cell is about 1.3:1 which is almost equal or higher than the human cells.
Although the number of bacteria is almost equal or higher than the human cell, the main reason behind this relation is that these bacteria live in the symbiotic or mutually beneficial relationship with humans.
Thus, a Symbiotic relationship is the correct answer.
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.
