Answer:
F1 Generation -
Genotype - GgRr
Phenotype - Green and round
F2 generation -
Genotype Ratio –
GGRR: GGRr: GgRR: GgRr: GGrr: Ggrr: ggRR: ggRr: ggrr
1:2:2:4:1:2:1:2:1
Phenotypic ration
Green & round: Green & wrinkled: yellow & round:yellow : wrinkled
9: 3:3:1
Explanation:
G represents Green seed color
g represents yellow seed color
R represents round seed
r represents wrinkled seed
Here G is dominant over g and R is dominant over r
F1 generation -
Genotype of true breeding parents will be
GGRR and ggrr
The offspring produced will be -
GgRr
Genotype - GgRr
Phenotype - Green and round
F2 Generation -
Genotype Ratio –
GGRR: GGRr: GgRR: GgRr: GGrr: Ggrr: ggRR: ggRr: ggrr
1:2:2:4:1:2:1:2:1
Phenotypic ration
Green & round: Green & wrinkled: yellow & round:yellow : wrinkled

The given question says that a student has constructed a model of cellular transport using fences and several gates.
This model can be used to demonstrate the cellular transport.
The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.
Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.
Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.
A fuel cell works like a battery. It consists of two electrodes where the reactions would occur and an electrolyte solution which allows for caharged particles to flow. In a fuel cell that uses hydrogen and oxygen as reactants. The hydrogen would enter the cell at the anode where oxidation would happen. So that the species that is formed in the anode side would be hydronium ions and electrons. The oxygen, on the other hand, would enter the cathode electrode where reduction occurs. The species that are produced in this side of the cell are water molecules. Together, the net reaction is called a redox reaction.
