Answer:

d. More than 95% of our DNA is non-coding DNA

Explanation:

In humans only about 1% of DNA is coding, that is, only 1% of our genome is composed of exonic regions capable of synthesizing proteins. Teherefore, the other 99 percent is noncoding. When this was discovered the scientists thought that 99% of non-coding DNA was "junk" , however,  now we know that some of the non-coding DNA is important to regualte  gene expression.

Answer:

alright bet I got this

Explanation:

Have you ever wondered what can happen to those plastic bottles you toss away? How do they decompose? What happens to them? Its simple really, they get eaten! No, not by people of course they are eaten by a tiny critter called a wax worm. The wax worms earn their name because they are often found living in beehives where they eat the beeswax.

Wax worms much like mealworms are used to break down things that would normally be endangering to our environment. These seemingly useless little animals do a whole lot for our environment especially with the amount of waste we produce! They really are a tiny secret hero to todays pollution problem.

After quite a few studies scientists are still unsure on how was worms can breakdown plastic with their tiny bodies but they appreciate the work these little recyclers do. They have a lot of theories on how these worms do this one of the theories is that bacteria can break it down, another theory is that enzymes in the worms intestines break down plastics. Though scientists believe it will take a while to figure this out they enjoy studying and learning more about this tiny helper.
