It is most likely true that there was a lower concentration of salt in the water than in the cells because when blood cells are put in a hypotonic solution such as pure water, the little to no salt concentration in the water causes the cells to swell and burst. This would occur because the water would try to dilute the solution inside of the blood cell and which would, therefore, cause it to burst. Hope this helps!
plants look green in sunlight because, all other colors except green are absorbed by the plants and only green color is reflected back, hence plants look green in sunlight.

of three things the photon passes through unscathed, the photon gets
absorbed by the electron of an atom and stays put, or the photon gets
absorbed and a second generation photon is generated by that electron</span>
Answer:
0.281 m
Explanation:
Applying,
W = 0.5ke².................. Equation 1
Where W = Workdone by the stretched spring, k = spring constant, e = extension/ compression of the spring
make e the subject of the equation
e = √(2W/k)................ Equation 2
From the question,
Given: W = 1.240J, k = 31.50 N/m
Substitute these values into equation 2
e = √(2×1.240/31.50)
e = √(0.07873)
e = 0.281 m
