<span>Oxygen travels to insect tissues through tiny openings in the body walls called spiracles, and then through tiny blind-ended, air-filled tubes called tracheae. Therefore, insects obtain oxygen through the spracles, which are small abdominal holes that lead into traecheal tubes called tracheae that branch into smaller tubes called tracheoles. From there, oxygen diffuses into body cells.</span>

The statement 'artificial selection decreases the rate of natural selection and change within a population' describes how artificial selection can decrease a population's biodiversity. It is a human-driven process.
<h3>Artificial selection</h3>
Artificial selection refers to the human-driven process by which different organisms (either plants or animals) are selected in order to combine desired features in offspring.
In artificial selection, organisms are mated (crossed) in order to select the progeny having desired phenotypic traits.
This process (artificial selection) leads to a decrease in natural genetic variation (biodiversity), which may have negative consequences in the successive rounds of selection.
