<span>1) The probability of F2 seed chosen at random will be yellow is the same as asking about the probability of forming a yellow seed in that generation. The answer is 3/4 (75%) because 1/4 = 25% GG is homozygous dominant and the rest 2/4 = 50% Gg are heterozygous.
2) In the F2 generation there are
two genotypes that will breed true, which is homozygotic genotypes: GG and gg. But of these two, only one of
them is yellow. The answer is 1/3 because from all the yellow seeds that resulted (GG, Gg and gG) only one has the genotype for true breeding.
3) The probability of taking out three seeds in which a least one is yellow can be calculated by subtracting the only
probability that doesn't fit the criterion, which is taking out a green seed 3 times:

= 1/64.
Then substract that to 1

=

4) there are three possible groupings in which the green is taken once and the yellow seeds taken twice. The first possibility (follow the example) is the green being the first to come out, another possibility is being the second and the last possibility is being taken in the third time.
For example, Green yellow yellow- probability : </span>
<span><span><span>

</span> = 9/64
This is one possibily, but since there are 3, multiply it by 3 and you obtain the final answer:2</span>7/64. </span>
While assessing a 35-year-old patient, the nurse hears a vascular sound between the xiphoid process and the umbilicus. What can the nurse presume from the sound?
Bruits
Answer: the major function of mucus is to protect the lung through mucociliary clearance against foreign and chemicals entering the lung.
Explanation:
the answer could not be D because a Golgi Apparatus is a tiny structure, or organelle, in a cell that "packages" nutrients for use inside the cell. The answer could not be c. because a nucleus is a tiny structure, or organelle, in a cell that "packages" nutrients for use inside the cell. The answer could not be Endoplasmic Reticulum because that is where proteins are transported from one part to the other. So the only answer left is Mitochondria, because the Mitochondriamain function is to produce ATP, the energy currency of the cell.
