Do some beak shapes allow birds to eat multiple types of food? Explain your answer.

Answers

Answer 1
Answer: Yes, but it depends on the habitat the bird is living in and how big the beak is itself. If the beak is small, the bird is not going to pick up something like a grape. hope that made any sense, the question is a little weird.
Answer 2
Answer: Yeah, probably because say a short wide beak allows the bird to crack nuts and a long skinny beak allows a bird to eat bugs out of trees and fruits then a beak somewhere in the middle of the two might allow them to eat both.

Which most likely describes a supersaturated solution? A. a hot solution with all of the solute dissolved
B. a cold solution with all of the solute dissolved
C. a hot solution with most of the solute resting on the bottom
D. a cold solution with some solute resting on the bottom

Answers

Answer is A. a hot solution with all of the solute dissolved.

A solution is a homogeneous mixture in which solute is dissolved in solvent. Solution may be unsaturated, saturated and supersaturated. Saturated solution is the solution in which solvent is not able to dissolve more solute at normal temperature.  But if you heat the saturated solution up to 80⁰C, the same solution able to dissolve more solutes making the solution supersaturated. Thus, a supersaturated solution is a solution that contains more solute than what the solvent can normally dissolve.

a. because when the solution is hot it is easier to dissolve the solute, and thus more solute can be dissolved in the same amount of solvent
