Following a meal, glucose must move from the gut lumen, where there is a high glucose concentration, through membrane proteins and into intestinal cells, where there is a relatively low level of glucose. this movement is called <u>diffusion</u>
This is simply because glucose moves from a region where it is highly concentrated in the gut lumen to a region of less concentration in the intestinal wall.
<h3>Diffusion</h3>
Diffusion can simply be defined as the movement of substances from a region of high concentration to a region of low concentration.
So therefore, Following a meal, glucose must move from the gut lumen, where there is a high glucose concentration, through membrane proteins and into intestinal cells, where there is a relatively low level of glucose. this movement is called diffusion

The agent of erosion is the pressure
After millions of years, the remains of living things will turn into fossil fuels which are natural fuels. The combustion of these fossil fuels is important for the running of machinery, raising temperature in reactions and many more.
<span>In a desert, water is in scarce supply, so excreting water would be a bad thing and might cause the death of any animal that does so due to dehydration.
There can be several different mechanisms to overcome this. One would be to have the bladder discharge urine into the large intestine where the water can then be reabsorbed into the body while the urea in the urine is passed out along with other solid wastes produced by digestion. Some other methods of conserving water would be for the kidneys to extract more water from the urine leaving the urine fairly concentrated. Also animals may behave in manners that conserve water such as staying in the shade during the day and only being active at night.</span>
Answer:
re-established colony is bottleneck effect and island colony is a founder effect
Explanation:
since the re-established colony was created after the death of a large number of lemmings, it was a random event so it is a bottleneck effect. the surviving lemmings that jumped into water made their own, new population, which would be a founder effect
