Achild and her mother are at the park. the child walks around the rectangular park while her mom waits on a bench. the child returns to the bench, finishing her walk at the same place she started. the park is 411 meters wide and 475 meters long. what distance did the child walk?

1772 meters was the distance the chield walked

Explanation:

The length of the area the child walked is given:  

475 meters wide and 411 meters long.

The problem also says, the child starts at point A (where mom is) and it ends at  in the same point A.

With this information, the distance the child walked was the whole rectangle: 411 (wide) + 475(long) + 411 (wide) + 475(long).

This means, the operation should be the following:

(475 x 2) + (411 x 2)  =  1772 meters

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.

explanation:

answer; i do believe that the correct answer is; ///mendelian genes are at specific loci on the chromosome and, in turn, segregate during meiosis;
