Answer:
the pH
Explanation:
The condition that should not be kept the same in each of the five test tubes is the pH.
Since <u>the aim of the experiment is to investigate the effect of pH on the activity of the lipase enzyme</u>, the pH is, therefore, the <em>independent variable</em>. Thus, it must be controlled or varied in all the test tubes in order to see its effect on the activity of the enzyme, which, in this case, would be the dependent variable.
I say A they dont neither grow or lower. and if they do they go back to normal
MRNA (Messenger RNA)
rRNA (Ribosomal RNA)
tRNA (Transfer RNA)
Answer: The motion is accelerated.
Step-by-step explanation: Given that the horse is walking along a straight line.
The horse travels 3 m in first second, so its speed is 3m/s.
In the next second, the horse travels 4 m, so its speed is 4 m/s.
In the third second, the horse travels 5 m, so its speed is 5 m/s.
Since the speed of the horse is increasing per second i.e., the speed in not constant, so the motion of the horse is accelerated.
Potassium is 10 to 20 times higher inside the cell, and sodium is 10 to 20 times higher outside the cell. The potential difference across the cell is important in several processes such as transmission of nerve impulses and maintain the ion balance.
The sodium concentration higher out side and potassium higher inside the cell then it moves two potassium into the cell where potassium levels are high and pump three sodium ions out of the cell and into the extracellular fluid.
This is due to action of membrane active transport system which pumps sodium out of the cell and potassium into it. Both helps in body maintain flid and blood volume so it can function normally.
