Answer:
18.28
Explanation:
Given:
Relation between the absorbance (y) and the concentration (x) as ;
y = 0.057x + 0.069
now,
we have to calculate concentration (x) for the given value of absorbance (y) = 1.111
thus, on substituting the value of y = 1.111 in the above relation, we get
1.111 = 0.057x + 0.069
or
x = 18.28
hence, the <u>value of concentration of sample is 18.28</u>
Answer:
D. predicting the age of the plant
Explanation:
stems don't exactly have those powers. but they do give support by holding the plant upright. they do give defensive properties. and they do increase the amount of sun exposure (like with sunflowers). but they don't predict anything.
