Answer:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b: Progeny ratio= 1: 1: 1: 1
c: 1/4
Explanation:
a. Genotype of male parent= BbNn
Genotype of female parent: bbnn
b. Gamete formed by the male parent: BN: Bn: bN: bn in 1:1:1:1 ratio.
Gametes formed by female parent: All gametes with "bn" alleles.
c. The probability that the offspring will have a genotype of Bbnn=
Bb x bb= 1/2 Bb: 1/2 bb
Nn x nn= 1/2 Nn: 1/2 nn
Therefore, probability that the offspring will have a genotype of Bbnn= 1/2 Bb x 1/2 nn= 1/2.
Answer: Option B
Explanation: First we should understand the role of enzyme and acid here. Pepsin is an enzyme which will break down proteins into simple monomers (like amino acids). And, acid causes digestion which means it will break down the protein into its respective elements and compounds. Water will act as a control in this experiment.
Option B is correct because it has all three criteria- 1. Control [water + protein] 2. With enzyme [egg white + pepsin] 3. With acid and enzyme
So this will give us an idea whether pepsin alone is breaking down the protein or digesting it. And there would be difference in test tube B and C. So this will clear the difference.
Option A is incorrect because it has not mentioned any different test tube for checking what happened with the protein. And, Option C is incorrect because mass of egg white will remain same after digestion also.
Question 2 is ansethosphere
Question 3 is high pressure(i think)
Answer:
Day-to-day changes in weather can influence how we feel and the way we look at ... Meteorology is the science of forecasting weather.
The letter should contain concerns about the causes and ill effects of erosion.
<h3><u>Explanation</u>:</h3>
Sir,
I am very sad to inform you that the town of Hariharanpur is suffering from continuous erosion for the last 3 years. Even after having proper knowledge about this fact, you being the mayor, are not taking any charge of this situation.
The town is situated just by the side of River Ganges which makes it's soil full of moisture. Along with the repeated deforestation and tree cutting for urbanisation, the smallest of the rain falls are also eroding a lot of soils. This can lead to severe landslides in river Ganges with severe loss of properties as well as loss of lives too.
So i request you to start embanking the river as well as to start planting new trees to save the town from getting lost under Ganges.
Thanking you,
XYZ.
