Answer:
A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism. Plants also exhibit phototropism, or growing toward a light source. This response is controlled by a plant growth hormone called auxin.
Explanation:
The formula is density = mass / Volume
density = ?
mass = 21 g
Volume = 9 mL
d = m / V
d = 21 g / 9 mL
d = 2.3 g/mL
Hope this help!
D=M/V
22.5/306.0=.074
.074ml is the density
The correct answer is C because diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.
HOPE THIS HELPS!
