Because of different DNA handed down from their ancestors, and different environmental effects.

The reason no child looks exactly alike is because everyone has a two pairs of copies of their genes, and these tend to be different, making it impossible to look exactly alike. Even twins. You can spot at least one difference, whether it be eye color, a mole, birth mark; the things that distinguish another person from another. This applies not only to children, brothers and sisters, but adults too.

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:

Year Calculation Est. Population

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

6th yr 13,979*105% 14,678

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