U4 L1 Quiz #1

Using Figure 1, which of the following scorpions has the highest toxicity level?

• Hairy scorpion

• All three scorpions have the highest toxicity level.

• Bark Scorpion

• Stripe-tailed scorpion

Scorpions have so many unique features that it’s easy to pretend they were invented by a nine-year-old: “They’ll have eight legs AND a big stinger AND huge claws AND two – no! – five sets of eyes…” They’re pretty much like insect superheroes, but they become supervillains as soon as they feel a threat coming on. If they need to defend themselves they can sting and inject poison from their tail. The toxicity of the poison is determined by their genetics. Toxicity means how badly a poison or chemical can hurt an organism.

• The higher the toxicity the higher the risk of harm.

• The higher the toxicity the lower the risk of harm.

• Chemicals only hurt humans.

• Chemicals only hurt scorpions.

What do DNA, genes and chromosomes do? These materials help make proteins for the body. You can think of them as similar to items used to make food in a kitchen. Genes are...

• the instructions, or recipe, for a protein

• storage for the instructions, like a recipe box

• the material that makes up the instructions, like the paper and ink of a recipe card

• molecules that build traits—think of them as the food made by following the recipes

The types and amounts of different proteins in the skin help determine the traits of the skin. Younger people make lots of the proteins collagen and elastin, so their skin is very smooth and stretchy. Why do older people have wrinkled skin that is less stretchy?

• Older people make less of the proteins collagen and elastin, so the structure of their skin changes.

• Older people have narrow blood vessels.

• Genes change as a person gets older.
