Explanation:
Primary cell walls are synthesized during growth and typically are relatively thin, pliant, highly hydrated structures. ... Secondary cell walls provide strength and rigidity in plant tissues that have ceased growing.
Answer:
These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation
Answer:
The correct answer would be carrying a box.
Work is done only when force is able to cause a displacement.
It can be calculated by multiplying the force applied (F) and the displacement (S) caused.
W = FxS
If the force applied and displacement are in the same direction then the value of work done is taken as positive.
In contrast, when the force and displacement are in opposite directions the value of the work done is taken as negative.
Lastly, when there is no displacement then the work done is zero.
In carrying the box, there is no displacement occur due to which work done is zero.
