Answer:
B
Explanation:
The experimental drug has a direct effect on the dependent variable which is the presence of the headache.
If the cell membrane were not selectively permeable, then unwanted substances would transfer through instead of being blocked out. Think of it like this: you have a sifter with various sizes of spice in it. You only want the finer grains of spice in your food, so when you shake the sifter, the larger pieces of spice don't fit through the small holes that only allow fine grains. Then you are left with the small spices in your food and the large ones stuck in the sifter.
Hopefully this helps and I wasn't too confusing :)
Answer:
<em>The correct option is C. Mendel's laws of segregation and independent assortment</em>
Explanation:
Mendel's law of segregation states that the two alleles of a gene pair segregate individually at the time of the formation of gametes. They also unite independently during the time of fertilization. We can see that in the scenario mentioned in the question, the alleles segregate independently.
Mendel's law of independent assortment states that the alleles of different genes assort independently at the time of gamete formation. Different traits are passed from the parents to the offsprings irrespective of one another.
That would be Hermodialysis {HD}
Answer:
B) The rabbits with medium length legs are the most stable and thus will out survive the others.
D) It is unlikely that evolution is occurring because none of the traits have disappeared from the population.
Explanation:
The graph shows that rabbits with longer legs are more likely to have a selective advantage that allows them to survive and reproduce than shorter legs. Throughout the generations, it shows that the number of short legs have decreased, and the number of medium length legs neither have advantage or disadvantage.
