Answer: C. The population size became limited due to factors such as availability of food.
Explanation:
Out of all the choices, C is the most likely to happen since more often then not, food runs out because a species has too many members. C is an example of the environment’s carrying capacity limiting the chipmunk species.
Since we are not told if the chipmunk population is really small, interbreeding may not happen. Predators hunt prey, not eat fruits like chipmunks do (I’m assuming what chipmunks eat.) If there was a predator species that came in, they would hunt the chipmunks instead of competing for the same resources. D just doesn’t make much sense in my opinion because that wouldn’t limit the chipmunk population.
If mitosis occurs correctly, the division of one cell by mitosis produces two cells.
You can't have a carrier with a dominant pedigree because other wise than individual or organism would be afflicted by the gene and render them incapable of being a carrier. A carrier is an individual/organism that has a normal phenotype (meaning it is not afflicted by said gene) but is carrying the gene that could cause disease or whatever the affect may be. In this case the gene would have to be homozygous recessive to be expressed. Hopefully this helps!
These alveoli are the smallest types of lung tissue, and one of the most important. In addition to being the primary means by which oxygen enters and carbon dioxide escapes the bloodstream, these small pouches of air are also the reason why the lungs do not totally collapse when a person breathes out. This is because they contain a cell that secretes a special chemical to lower the surface temperature to prevent lung collapse. The alveoli also contain other cells that secrete chemicals to attack and remove any foreign objects in the lungs, such as dust, dirt and other debris.
In addition to making up alveolar sacs, alveoli also form alveolar ducts. It is estimated that there are more than 300 million alveoli in the human lungs, all of which are located in either alveolar ducts or sacs that are found at the end of the smaller passageways, or bronchioles, in the lungs.
SHORT ANSWER:
Alveolar sacs contain tiny pouches called alveoli, whose primary function is gas diffusion. These clusters of alveoli have thin walls that allow oxygen to pass easily from the lungs into the bloodstream and carbon dioxide to flow from the blood to the lungs so it can exit the body.
