I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.
We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.
It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
Answer:
The correct answer would be -
1. the ocean have
2. water
3. acidic.
Explanation:
Carbon dioxide fro the atmosphere dissolves in the seawater naturally. This process can be understood by the following process:
Water and carbon dioxide reacts to form carbonic acid that can dissociate into either carbonate ion or bicarbonate ion:
1. CO2 + H2O ====> H2CO3⁻ (carbonic acid)
2. H2CO3⁻ ======> H⁺ + HCO3⁻ (bicarbonate ion)
3. H2CO3⁻ ======> 2H⁺ + CO3⁻ (carbonate ion)
Due to the presence of proton ions in seawater, seawater becomes more acidic. As hydrogen ions bind to the carbonate ions to make bicarbonate ions, the carbonate ion reduced which is required to form the
Answer:
The DNA polymerase is the enzyme which copies in the direction of 5' to 3' in the leading strand and in case of lagging stand it is opposite. that is from the 3' to 5'.
Replication in the 3' to 5' takes place in the fragments which is laid by the Okazaki fragments. These small fragments are kept together by the help of the enzyme known as DNA Ligase. So, called as discontinues
Incase of leading strand, the strand is in the same direction of the for the process of replication (5' to 3'). So it is continuous.
Hence, the whole process is a combination of continuous and discontinuous DNA synthesis.
Answer:
2)
Explanation:
The positive control is the treatment where bacteria grew without lead. Since positive control indicates the presence of bacteria in the experimental conditions, it is possible to confirm that they only death in presence of this metal. However, it is important to note that it is imperative to repeat this experiment three times and also to include a negative control in order to confirm these results.
