A.) Veins in the pulmonary circuit carry oxygen-rich blood
red blood cells are used to circulate oxygen through out the body, thus it is true.
<span>If each of the pairs of
chromosomes was heterozygous (what gives you the highest potential
number of different gametes), then the number of possible gametes
increases from 4 to 8 for a diploid organism. To figure out how many
are possible, raise the number of homologous chromsomes (2 for a diploid
organism) to the power of the number of chromosomes. So if you have
two different chromosomes (A and B), raise 2 to the 2nd power (or
multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C,
then you have 2^3, or 2 x 2 x 2 = 8.
To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc
gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>
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.
Answer:
When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. It can breed and spread quickly, taking over an area. Invasive species can change the food web in an ecosystem by destroying or replacing native food sources.
