A muscle cell has a solute concentration of 2% it is in a solution of 5% solute. What will happen
to the cell?
Answer:
But now you have two mixtures of different solute concentrations. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower solute concentration is hypotonic
Explanation:

The cell will shrink as the solvent from low concentration solute will move towards the high concentration solute.
What is osmosis ?Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
Since the solute concentration in the muscle cell is just 2%, and the muscle cell is dipped in a solution that contains 5% solute, the solvent will flow from the muscle cell into the solution. This will result in the muscle cell becoming smaller until the concentration of solutes on both sides is equivalent.

4. The stars at the edges of a galaxy are rotating around the galaxy’s center at the same speed as the stars in the middle of the galaxy. How does this provide evidence of dark matter?
Dark matter absorbs light from outside the galaxy, allowing the light of the stars in the galaxy to show the orbital speeds of the stars.
Dark matter emits the light that astronomers need to see the orbital speeds of the stars.
Dark matter subtracts gravity, which allows the stars to rotate at the same speed.
Dark matter provides the gravity that allows the stars to rotate at the same speed.
Answer:
Dark matter provides the gravity that allows the stars to rotate at the same speed.

Please don't use these answers to cheat they are for help.
The statement shows that D. Dark matter provides the gravity that allows the stars to rotate at the same speed.
According to the information given in the question, it should be noted that the stars at the edges of a galaxy are rotating around the galaxy’s center at the same speed as the stars that are in the middle of the galaxy.
This implies that dark matter provides the gravity that allows the stars to rotate at the same speed. It should be noted that dark matter doesn't emit the light that astronomers need to see the orbital speeds of the stars.

what three patterns of biodiversity did darwin observe
Answer:
Species vary globally, species vary locally, and species vary over time.
Explanation:
Darwin noticed three distinctive patterns of biological diversity.
Charles Darwin observed three patterns of biodiversity during his exploration on the voyage of the HMS Beagle and in his subsequent research:
Species Variation: Darwin noticed that within a particular species, there is a wide range of variation among individuals.
Geographical Distribution: Darwin observed that different regions of the world have distinct sets of plant and animal species.
Fossil Record: Darwin studied the fossil record and recognized that it contains evidence of extinct species that differ from those currently living.
Thus, these three patterns of biodiversity species variation, geographical distribution, and the fossil record were instrumental in shaping Darwin's theory of evolution by natural selection.
