Jenna knows that cystic fibrosis runs in her family and she is worried she might carry the gene. she is marrying tyler, who does not think that cystic fibrosis runs in his family. jenna and tyler are getting married, and plan on starting a family. identify the unresolved problem they will share as a married couple.
a.
tyler does not know if cystic fibrosis runs in his family.
b.
jenna does not know if she carries the cystic fibrosis gene.
c.
jenna and tyler do not know the chances of passing on cystic fibrosis to their future offspring.
d.
jenna and tyler plan on staring a family.

The correct answer is c.   Jenna and Tyler do not know the chances of passing on cystic fibrosis to their future offspring.

Cystic fibrosis is a genetic disorder which can be inherited from the parents. This disease affects mostly lungs but can affects liver, pancreas and other organs of the body such as digestive system.  Cystic fibrosis can occur in offspring when he and she inherit one copy copy of gene that causes  cystic fibrosis from each parent. In this question Jenna knows that she may carry a gene that causes cystic fibrosis but Tyler seems to be a normal man who does not gene causing cystic fibrosis.  

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
