Answer:
Explanation In order to set up a dihybrid punnet square you must figure put the parents first.
since the first parent is homozygous that means the alleles are the same and since its dom that means alleles are dom. so they would be RRTT
The second parentis Heterozygous which means the alleles are different. This would be shown as RrTt.
when setting up the punnet square the boxes we use to represent the parents are composed of the possible outcomes. In this case the only outcome for the first parent is RT RT RT RT
The second parent has a bit more variation as the possible combinations are RT rT Rt rt
after writing those what you have left is the possible combinations and their genotypes
I added an attached file of the completed square
For the questions what you have all you have to do is follow the chart made
a) 100% and the possible genotypes are RRTT RrTT RRTt RrTt
b) 0% ad none
c) 0% and none
The most important factor which determines whether the living things can survive in a body of water s its salinity. The salinity level of the water is the factor at play in deciding which of the living organisms live inside the water. The salinity of the organisms has to be similar to the salinity level of the water in order for them to survive, otherwise, they will be dehydrated as a result of osmosis.
Hence, the answer is 'salinity'.
Still create mor which is called celluar respiration
The dam could burst or, if not properly constructed cause water to spill over the sides and top of the dam. Hope this helps.
