What plant physical structure or organ has a similar function to the internal skeleton of an animal?

Stamen
Bark
Stem
Pistil

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

heats surface water up

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
