Answer:
Steel
Explanation:
In fact, sound waves travel over 17 times faster through steel than through air. Sound waves travel over four times faster in water than it would in air
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.
Answer:
the answer is :
Lane 3 contains the longest DNA fragment
Carrying capacity is the maximum amount of organisms a certain ecosystem can sustain with the resources available in a given ecosystem.
Factors that could either increase or decrease the K, carry capacity, would be: drastic weather causing depletion of resources, decreases in competition, etc.
