Answer:
YES. This information is enough to assume that neither of the blood groups dominates over the other one.
Explanation:
<u>Available data:</u>
- A man with blood group B ----> Genotype IBIB or IBi
- A woman with blood group AB ---> Genotype IAIB
- Their daughter has blood group AB --> Genotype IAIB
The fact that the daughter´s genotype is IAIB tells us that she got the IA allele from the mother, who is IAIB, and the IB allele from his father, who is IB-.
- If blood type B was dominant over A or AB, then the daughter should have Blood type B.
- If blood type A was dominant over B or AB, then the daughter should have Blood type A.
- Blood type AB tells us that both types are being expressed, A and B.
The fact that the daughter inherited one type of allele from each parent, but she is expressing the blood type AB, suggests that neither of the alleles dominates the other one. This is an example of co-dominance, where the heterozygote phenotype is an additive expression of both of the parents' genes.
This is enough information to assume that neither of the blood groups dominates over the other one.
Answer:
option A
Explanation:
Cones provide colour vision while rods cells do not produce colour vision. Rods provide the vision in the dull light (darkness or night), whereas cones are known to give the vision during the day or bright light; Rod cells are more sensitive to light than cone cells and both do have visual pigments with the rod cells possessing rhodopsin and the cone cells having photo-opsins.
Which statement about bases is incorrect?
Answer:
Bases contain hydrogen ions Is the Correct Answer!
A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way.

Jet airplanes take up a lot of fuel and money. Not only are they burning fossil fuels quickly, but they're also being flown on a basis. Planes are sent out constantly, and the amount of carbon it releases into the atmosphere is incredibly dangerous.
Watershed is the place where water of rain and snow get stored. The watershed contains surface water-and wetlands--and all the underlying ground water,lakes, streams, reservoirs. Lake is the major component of the watershed . The watershed can be used for various purpose like dams, hydrological modification etc.
