Answer:
Glucose entering the intestines from the villus.This is by active transport.The latter is defined as the movement of molecules and solutes from the region of lower concentration to the region of higher concentration against the concentration gradient.
Explanation:
All the above options depends on the diffusion gradients from one higher region to another.e.g oxygen passing from high concentration from outside to lower concentration in blood stream,like wise Co2 from higher concentration from inside to outside,with passive diffusion lipids and water enter the small intestine(note amino acid and glucose,and fructose are different).
Active transport( through sodium dependent transporter) transports glucose to the intestine from the villus.This is movements against concentration gradient because,glucose molecule are concentrated in intestine,and needed by the cells, in the body.Therefore they must be transported as a fast rate inn the blood .
However the absorption by the villi is very slow,therefore active transport is needed to move these against the concentration gradient into the intestine.And finally the blood.
If this were to be moved by passive diffusion,the high concentration in the intestine will force this back into the villi
Therefore extra energy is needed by active transport for the glucose molecules to enter the intestine from the villus.

a bacteria takes a longer time to spread throughout the body
Mitosis is the type of cell division the question is asking for
Both the force of windshield on the bug and that of the bug on the windshield are equal but in opposite direction.
<u>EXPLANATION: </u>
When the vehicle is moving forwards and air flows around it, and it also causes the flying bugs to hit the windshield. This impact causes a force that is imparted on both the bug and the windshield.
Thus both the bug and the windshield experience equal and opposite reactions result in Newton's Third law of motion. According to this law, it states that there will be an equal and opposite reaction for every reaction.
