Explain the importance of scientific names.
prohojiy [21]

Answer:

Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species.

Answer:

When the rule of 70 applies to population, dividing 70 by the percentage of population growth should equal the time (in years) that the population needs to be double (option A)

Explanation:

The rule of 70 is useful to calculate the time in which a variable of any type can be duplicated. The calculation is done by dividing the number 70 by the percentage of growth of the variable.

<u>If the rule of 70 is applied to the population, it is possible to calculate, based on its growth rate, the time that population would need to double</u>.

If, for example, the growth rate of a population is 3 percent:

70 / 3 = 23,33

This indicates that a population, with a growth rate of 3% would need about 23,33 years to double.
