Answer:
Explanation:
In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.
It would in fact be lethal. The main function of the digestive system is just that, to digest food. Both intestines play an important part in the digestive system( to digest and absorb all nutrients possible from stomach contents) The function of the large intestine is to absorb water, left over nutrients from the small intestine and, electrolytes. It would be equally if not more deadly if the small intestine couldn’t absorb nutrients. Since the small I intestine also plays an important role with providing the body with nutrients and other vital materials it would be deadly if you could not absorb anything. You would go into a state of malnutrition and would need to be treated immediately.
The answer is C. Genetic drift is the change of an allelic frequency due to random sampling in a population. When the brown and black bottles are preyed upon compared to the green bettles, their numbers in a population decrease. Therefore the next generations/offsprings of bettles population is more likely to be of green beetles since they will be more in the parent population. The allelic frequency of the allele for green bettles becomes higher than that of brown and black beetles. Eventually, after generations, the black and brown beetles may be eliminated from the population
Answer:
The answer is: The lac operon transcription would be reduced.
Explanation:
The lac operon is the machinery that bacteria uses to break down lactose to use it as an energy source when there is no glucose around. The catabolite activator protein (CAP) senses glucose via a molecule called cAMP. If the levels of glucose are high then no cAMP is produced and therefore no cAMP would be able to bind CAP. That would leave CAP inactive and the transcription would occur but at low levels. The same would happen if CAP protein would have a mutation that would leave it inactive.
