Answer:
The males can only either be black or orange
Explanation:
There can be no male calico because for an offspring to be a calico the two codominant alleles must each be carried on the two X chromosomes and in the males, there is the presence of just one X chromosomes, thus they can either be black or be orange. For the females, the can only be black if they carry the black allele on both X chromosomes, the same goes for the orange.

Answer:
True, planets are round because of gravity
Among the listed plants above, the one that we can expect to grow lowest to the ground would be the hornworts. Hornworts are non-vascular plants which can be found both on water and land. Since these plants do not have a vascular system, it is hard for them to move water internally due to the force of gravity which explains why they cannot grow more above the ground.
The answer would be m<span>ycoplasmas. These type of organisms are very unique, because their membrane lacks a cell wall.</span>
The correct answer is B.
On this graph we can observe the workings of the stabilizing selection. Stabilizing selection tends to favor the average phenotype and eliminate the extremes. Essentially, this means that the natural selection is selecting the mean value of a trait as optimal. In our case, the mean weight of newborns is selected as optimal, because newborns born with less weight can be too weak to survive and the ones that have too much weight (are too big) can hurt the mother during birth.
