Observe the two plants. which cellular change affected the structure of second plant

The correct answer is option D which is release of water from the vacuoles.

Explanation:

The difference in second plant from the first one is rigidity. Second one is wilted and not rigid. This is due to the release of water from the vacuoles in the cell of plants.

Vacuoles are present in the center of plant cell. They are usually filled with water and provide structural support to the cell.

In the absence of water filled vacuoles, plants shoots are wilted as in case of second plant.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
