The genotype and phenotype ratio for the first cross will be 100% Rr and 100% round, while the second cross will be 1RR:1Rr, 50/50 round and wrinkled respectively.
<h3>Monohybrid crosses</h3>
Assuming that the seed shape allele is R(r).
For the first cross: RR x rr
Rr Rr Rr Rr
Genotype ratio = 100% Rr
Phenotype ratio = 100% round
For the second cross: RR x Rr
RR Rr RR Rr
Genotype ratio = 1RR : 1Rr
Phenotype ratio = 50% round and 20% wrinkled.

Answer:
Explanation:
Q = m × Cp × delta T
Where,
Q is the heat gained by water
m is the mass of water
Cp = specific heat capacity of water
= 4.18 kJ per kilogram per degree Celsius (J/kg°C).
This means that it takes 4,180 J to raise the temperature of 1 kg of water by 1°C
delta T is the difference in temperature
A.
The smaller beaker had a bigger temperature rise because the same energy has been given to a smaller number of water particles in the beaker than those particles in the large beaker so each particle is moving faster than those in the other beaker.
B.
Since both beakers were heated at the same time, they both gain the same amount of energy.
Qlarge = Qsmall
Answer:
A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.
Explanation:
Electrochemical cell -
Device used for the conversion of chemical energy to electrical energy is called electrochemical cell.
it is based on oxidation reduction reaction.
Electrolyte is a solvent in which ions are dissolved and two electrodes are dipped in it.
Anode electrode is responsible for oxidation, and the cathode electrode is responsible for reduction.
The electrochemical cell is composed of two electrodes dipped in an electrolyte , and which are further connect by salt bridge .
Salt bridge firstly connects the circuit and allows the movement of ions and , resists any mixing of the solution , and helps to maintain the electrical neutrality condition .
Hence , from the question , the correct option about salt bridge is the first option .
