The Osmosis Gizmo portrays a cell (red square) in a solution of purple solute particles dissolved in green solvent particles. Pr
baherus [9]

Answer: The particles that can pass through the cell membrane are the GREEN SOLVENT PARTICLES.

Explanation:

OSMOSIS can be defined as the thermal movement of solvent (water molecules) through a selectively permeable or semi-permeable membrane from a region of high concentration of the solvent to one where they are in low concentration.

The cell is bound by a membrane called plasma membrane. This membrane is selectively permeable and allows water and certain dissolved solvents to pass through it. As a result, the plasma membrane of the cell regulates the movement of materials between the cell and it's environment.

From the osmosis gizmo, it portrays a typical example of osmotic reaction occuring between a cell immersed in a solution of purple solute particles dissolved in green solvent particles. In order to maintain an osmotic balance between the cell and the solution surrounding it, the solvent (which is the green solvent particles) will move from the region of higher concentration to a lower region through the cell membrane

Lubov Fominskaja [6]

Answer:

a- brown eyes

b- blue eyes

c- brown hair

d- widows peak

e-short arms

f- can roll tongue,  long arms

g- brown eyes, brown hair

h- widows peak, short arms

i- brown eyes, can roll tongue

j- brown eyes, brown hair, no widows peak, long arms, can't roll tongue

Explanation:

So the capital letter is the dominant trait, and the lowercase letter is recessive. The capital dominant trait will always overpower the lowercase recessive trait. So the only way the recessive trait can be seen is if there are two together. So... if R is white fur and r is brown fur...

RR would show the dominant trait of white fur

Rr would show the dominant trait of white fur

rr would show the recessive trait of brown fur
