In the formula Lt = L0 + rt, what does ‘Lt’ represent?
In the formula Lt = L0 + rt, what does ‘Lt’ represent?
Options
- ALength at time zero
- BLength at time ‘t’
- CGrowth rate
- DElongation per unit time
Correct answer
B. Length at time ‘t’
Step-by-step solution
On plotting the length of the organ against time, a linear curve is obtained. Mathematically, it is expressed as
Lt = L0 + rt
Lt = length at time ‘t’
L0 = length at time ‘zero’
r = growth rate / elongation per unit time.
