Answer:
frictonal force due to the surface of irregularities
They would be likely to be underweight. This is because the role of villi is to increase absorption of soluble molecules, they do this by increasing surface area for absorption to occur across.
If the person has less villi than normal in their small intestine, then the surface area will not be as large meaning there is less area for absorption to occur across so less soluble molecules will be absorbed.
Answer:
True. mark me as Brilliant
Neutral reaction is the reaction that occurs when an acid cancels with a base
Answer:
If force is applied to cause the motion of the body
Explanation:
In the setup given in this diagram, potential energy can be converted into kinetic energy by applying force on the cart or object to move it down the slope.
Potential energy is the energy due to the position of a body. The body has huge potential energy at its current position.
Kinetic energy is the energy due to the motion of a body.
As the body moves down the slope and its velocity increases, it gains massive kinetic energy.
Down the slope, the kinetic energy increases as the potential energy decreases.
At the bottom of the slope, the potential energy becomes zero and the kinetic energy is at its maximum.
