Biology
1 answer:
Rasek [7]3 years ago
4 0

Answer:

Through genetic modification/engineering

Explanation:

<em>Most of the species that we use as food do not look like their ancestral species anymore because humans have genetically modified them to suit their desires.</em>

Through genetic engineering, humans have been able to select desirable characteristics or attribute from one organism and transfer it to another organism of similar species that already has some desirable attributes. Thus, the latter organism becomes genetically modified and looks different from its ancestors just to suit the taste of man.

Capillaries are tiny blood vessels in the circulatory system that connect aterioles to venules. They are the most abundant or they are much blood vessels. They can penetrate the tissues of the body which allow passage of food nutrients, oxygen in the body thereby allowing exchange of nutrients and oxygen between the body tissues and the blood.
