Several experiments in the 1800s demonstrated that the tips of plants are responsible for detecting light, which causes the stem of the plant to elongate and bend towards the light.

Which of these phrases are accurate about the experimental design and its validity?

The experiment should be repeatable by the same researcher.
The experiment should be replicated by different researchers.
A control plant with no light or top light would likely show no bending.
All species of plants behave the same way.
The light levels should increase during the experiment as the plant grows.

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
