The smith family is afflicted with a genetic disorder known as pinocchio nose syndrome, which causes affected adults to grow noses in excess of five inches long. 100 members of the smith family show up for a family reunion. of the fifty-three women, thirty-seven have unusually large noses. of the forty-seven men, thirty-six have an enormous nose. based on these figures, pinocchio nose syndrome is probably

dominant and not sex-linked

Explanation:

As we can see, the number of women in the Smith family who have Pinocchio's nose syndrome is very balanced with the number of men in the Smith family who have Pinocchio's nose syndrome. With that, we can say that this syndrome is not caused by an inheritance related to sex, otherwise we would see a greater number of men or a greater number of women who have the syndrome. An example of sex-related inheritance is baldness, since the number of bald men in a family is much greater than the number of women.

Furthermore, we can say that this syndrome is caused by a dominant inheritance. This is because the majority of individuals in the family have the syndrome. In a population the number of heterozygous individuals and dominant homozygotes is much greater than the number of recessive homozygotes.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
