A scientist is studying the population of a particular species of beetle in an ecosystem. The beetles currently have an estimate
Snowcat [4.5K]

Answer/Explanation:

Given an estimated beetle population of 11,500, of which it is estimated to increase approximately by 5% each year, we can calculate the estimated population for each year as follows:

<u>Year                       Calculation         Est. Population</u>

1st yr (current yr)                                   11,500

2nd yr                     11,500*105%          12,075

3rd yr                      12,075*105%         12,679

4th yr                      12,679*105%          13,313

5th yr                      13,313*105%           13,979

<u>6th yr                      13,979*105%          </u><u>14,678</u>

The above is how the table would like showing the estimated population for each year.

Explain in your own words why a dominant trait is not always a common trait.
taurus [48]

Answer:

Describing a trait as dominant does not mean it is the most common; it means that it is expressed over the recessive trait. For example, tongue rolling is a dominant trait, controlled by the dominant version of a particular gene (R). Individuals with one or two copies of R will exhibit tongue rolling.
