Which type of blood vessels contain thick muscular tissue within their walls to pump blood throughout the body?

Artery

Explanation:

The artery is a hollow tube that possesses a wall that is made up of thick muscles that enables it to withstand high  pressure of the blood that is being pumped out from the heart. Arteries conduct blood away from the heart.

The arteries are blood vessels that carry blood away from the heart, and supplies to other parts of the body. The pulmonary and the umbilical arteries carry deoxygenated blood to organs like the lungs, which oxygenates the blood, while the other arteries carry oxygenated blood from the hearts and nutrients to other parts of the body for cellular functions .

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:

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
