It is true that z<span>oning laws may designate parcels of land for specific uses, but sometimes the economic benefit of developing wetlands, grasslands or forested areas overrules the protection of such land.
This is especially true if a rare plant or something thought to be extinct starts growing there - then the nature cannot be disrupted so as to make a building or something else there. </span>
The answer would be D.: <span>Helicases separate the two strands of the double helix, and DNA polymerases use each of the original strands as templates to create two new strands. :)</span>
The kind of cell division that goes with growth is Mitosis. Mitosis cell division is accompanied by cellular enlargement and differentiation, so there is an increase in size and weight. I hope this helps!
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.
