Read the following hypothesis about why a chicken bone becomes bendy after being soaked in vinegar:

the bone can bend because the acid in the vinegar has removed the calcium that made it hard.
what prediction could be made based on this hypothesis?

a.
an acidic substance like many drinks wouldn't make bones bendy.

b.
acids are very powerful substances and should be handled with care.

c.
other kinds of bones containing calcium wouldn't get bendy in the vinegar.

d.
if the acid was separated from the vinegar, chicken bones wouldn't become bendy in the remaining vinegar.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

gans

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the answer is the index of refraction of the second medium is higher. i just took the test.
