Answer:
Let:
Y = Yellow R = Round
y = green r = Wrinkled
If you look at the F1 generation, all the plants are round and yellow, so these are the dominant traits and each offspring is heterozygous for both traits. The cross for the F2 generation would then be:
<em>YyRr x YyRr</em>
In a Punnett it would look like the attached picture.
For the forked-line diagram, first you will need to know the gentypes and ratio of each trait in a monohybrid cross. Select one trait, and then branch each gentype to the next trait, linking it with each possible genotype combination of the monohybrid cross.
Attached is a picture of the Forked Branch diagram for this cross.
Clearly the onion cell consists of a cell wall, because an onion is a multicellular plant organism.
Multicellular means; consisting of many cells.
The outer layer of the skin covering the exterior body surface<span> of vertebrates ... the primary tissue of higher plants composed of </span>thin<span>-walled </span>cells<span> that remain capable of ... a swelling on a plant stem consisting of overlapping immature </span>leaves<span> or petals ...

I think the correct answer from the choices listed above is option A. The balanced equation representing the decomposition of lead oxide would be that <span>PbO2 = Pb + O2. It decomposes into oxygen gas and lead metal. Hope this answers the question.</span>
They are thought to share common ancestors. I think this is the right answer.
Hope this helps :)
