The key lesson learned from what has happened on the Easter Island is that the humans should live in balance with the nature and to use the natural resources responsibly. The Easter Island was inhabited by people until relatively recently, and they lived on the island for some time, but there's nothing left from them apart from numerous large heads made out of stone. The people that lived on the island died, and that happened because of their irresponsible way of using the natural resources and destroying the environment. The people that lived on the Easter Island managed to use and destroy all natural resources that were enabling their survival there, putting themselves in a situation where they didn't had anything to eat, nor having material to build boats and move on another place. They were tuck there, isolated, started to kill and eat each other until the last one of them was left and died. This is a very nice example and lesson for the humans in the present that they should be very careful with the nature and the natural resources because there's always a line that after it is crossed there's no coming back.
Answer:
motion and kinetic energy
Explanation:
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.
