ankoles [38]

Answer:

Following are some of the possible consequences of mutations:

1. Some of the mutations take place in proteins that play an essential role in the function of cells, and thus, the cell dies.

2. Some mutations result in the origination of new traits like red hair.

3. Some mutations take place in genes, which monitor the division of cell and thus cells start to divide out of control, resulting in cancer.

4. Some of the mutations may be beneficial and may offer some benefit to the organism in some of the environments. These advantageous mutations may be encouraged by natural selection and are the basis for the evolution of life on Earth.

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.
