The manipulation of DNA within cells to improve the production of materials or the material itself is called genetic engineering

Explanation:

Genetic engineering is the use of recombinant DNA to transform the genetic composition of an organism. Generally, humans have indirectly manipulated the DNA through reproduction control, for example, the selection of offspring that have the desired characteristics. Genetic engineering involves the manipulation of one or more genes. A gene from another species is introduced into the genome of another organism so that the desired phenotype is produced.

answer; /// i believe that the correct answer is (50%);

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
