Answer:
D. Both Genetics and the Environment
Explanation:
Getting a pierced ear is both a genetic and environmental trait because, in males, it is not genetically transferred, rather it is a choice to manually pierce the ear maybe at birth, or much later in life. In females, however, pierced ears is a genetic trait because it is gotten naturally when they are born
These environmental factors include where a person stays, the kind of friends they keep, and people they try to imitate. Ear piercing is something that is done manually for males for various reasons.
The answer is D a nucleosome; a nucleosome has DNA wrapped around histones which prevents chromatin from tangling :)
We could possibly use water as a fuel source, rather than fossil fuels (which are limited)
Science has already developed something of the sort, and with using water as a fuel source for say vehicles and such, it's inevitable for a positive change to happen because there would be less carbon monoxide; which means less polution.
<span>Biologists who work in the fields of genomics and molecular biology study DNA genome content and analyze genetics on a molecular level. They do it to map DNA and use it to prevent diseases or anything similar.</span>
