Digestion starts in the "mouth" and continues in the stomach. The small intestine completes the digestion process.
They move by osmosis(a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.).
Answer:
It will plateau and the population will stabilize in relationship to available resources.
Explanation:
Having an unhinged rabbit population with no predators and an abundance of food will cause the population to initially increase. This increase will be due to an environment free from predation and also encouraged by an abundance of food.
In time these rabbits will increase in number and will put a strain on food supply. Dwindling resources will put pressure on reproduction. In addition to this these have a limited gene pool since they have been only reproducing with each other. This will pass along any disease sensitivity that they may have. In the even that a disease is introduced into the population many of them will be wiped out.
In conclusion, without a constant food supply to support a growing population the rabbit population will not multiply exponentially, indefinitely.
Answer:
The correct answer is an allele.
Explanation:
The variant form of a gene is termed as allele.Some genes exits as various different forms at a specific position on a chromosome also called genetic locus.
Humans are diploid organism.The diploid nature is due to the presence of two allele at each genetic locus among them one allele is inherited from paternal origin and the other allele is inherited from maternal origin.
In order for offspring to have a dominant mutation, they need at least one copy of the allele from either or both parents. So yes, at least one of the parents must have the mutated gene in order for the offspring to have the mutation.
For your second question, I'm not quite sure what you mean so I will restate two possibilities for what I think you mean:
1. The offspring does not have the mutation if none of the parents have the mutated gene: this is correct.
2. If the mutation is recessive and the child has only one copy of the mutated allele, then the child will not show the mutation. If none of the parents had the mutated gene, then it would not be possible for the child to have the mutated gene or show it.
