The kinetic energy of 6250 J equals 6250 J work-done in stopping the object in motion.
The given parameters;
- <em>Kinetic energy, K.E = 6250 J</em>
According to work-energy theorem, the work done in stopping a moving object is equal to the kinetic energy of the moving object.
Kinetic energy is the energy possessed by an object by virtue of its state of motion.
Work-done in stopping the object in motion = K.E = 6250 J.
Thus, we can conclude that the kinetic energy of 6250 J equals 6250 work-done in stopping the object in motion.

Answer: A. The onion cells have lysosomes, and the cheek cells do not.
Explanation:
Answer:
The correct answer is A.
Explanation:
Diffusion is the net movement of a substance from a region of higher concentration to a region of lower concentration. The difference in concentration between two environments creates a concentration gradient which is what drives diffusion. Therefore, this movement does not require aid such as extra energy molecules for active transport or integral membrane proteins for directed movement, hence the answer is not B nor C. If the cell is in equilibrium with its environment, it means that the concentration of substances inside the cell is equal to the concentration outside the cell, and any movement that takes place will be random movement of substances across the plasma memberane. Movement in the cell will not cease as the cell is still active. Therefore, the answer cannot be D either.
The RYR1 gene is responsible for producing the protein ryanodine receptor 1. This protein transport calcium ions to the cells for muscle contraction. When this receptor remains open for a long time, you would expect an excess of calcium ions which would result to muscle rigidity. The excess calcium ions would also increase body temperature and produce excess acid.
