Denise heats a beaker of dilute acid on a hot plate in a fume hood. what should denise wear to best protect herself when she transports the beaker to a balance outside the hood?
a. heat-proof gloves, a lab coat, and close-toed shoes
b. goggles, a lab coat, and close-toed shoes
c. goggles, a lab coat, and heat-proof gloves
d. goggles, a lab coat, heat-proof gloves, and close-toed shoes

The correct answer is D. goggles, a lab coat, heat-proof gloves, and close-toed shoes

This will protect her from everything since the fumes could enter her eyes, or they could spill on her hands, body, or feet, so all of this protection is necessary if it is an acid. 

Option (D) is the correct answer.

Explanation:

Working in a laboratory can be dangerous if proper precautions are not followed.

Since, Denise heats a beaker of dilute acid on a hot plate in a fume hood so, he should be wearing goggles, a lab coat, heat-proof gloves, and close-toed shoes.

This is because even if accidentally acid spurts or falls on his feet then his skin must be covered so that he doesn't get burned.

The correct answer is 2nd statement.

Explanation:

Both the chicken embryo and the embryo of a cow look quiet identical as they both are distantly associated, and thus, it can be concluded that their development would be identical. The development of both the cow and chicken at the beginning similarly takes place. The resemblance in the development of both the embryos is the same because of the similarity of both ancestors.  

This suggests that both the chicken and cow have originated from a similar organism, and then afterward got diverged into distinct species. It has been found that the organism that exhibits the same kind of embryonic development demonstrates similar ancestry.
