Answer:
Colistin is a last-resort drug. It is used only when all other drugs fail. These bacteria have developed resistance to colistin. Scientists fear that the bacteria could one day mutate, and it would be almost impossible to treat with current medications. However, this is not the case right now because the bacteria in question do not have a resistance to other antibiotics. Scientists recommend using antibiotics only when it is absolutely necessary to help ensure that drug-resistant bacteria do not grow and multiply rapidly.
This is straight from the course.
Answer:
the independant variable the amount of light on each plant
Explanation:
Answer:
The genotype of the randomly chosen F1 parent plant is "Tt"
Explanation:
Let "T" represents the allele for tall height characteristic of plant and "t" represents the allele for short height characteristic of plant.
Given -
Two phenotypically tall heterozygous pea plants are crossed to one another.
Genotype of tall heterozygous pea plants would be "Tt"
F1 Generation -
Tt * Tt
TT, Tt, Tt, tt
Now, it is given that a phenotypically tall F1 progeny plant is randomly chosen and mated to a phenotypically dwarf pea plant.
Genotype of phenotypically dwarf pea plant would be "tt"
Also, it is given that some of the F2 offspring from this mating are phenotypically dwarf this implies that progeny selected from F1 generation must have an allele for short height characteristics i.e "t"
Therefore,
in F2 generation cross will take between tt * Tt
thereby producing Tt, Tt, tt, tt
Therefore, the genotype of the randomly chosen F1 parent plant is "Tt"
Answer:
A play
Explanation:
I mean-
If its a work by Shakespeare, its most likely a play!
Answer:
The cross between two plants of heterozygous genotype i.e. two pink-coloured flowers will result in progeny/ offsprings having one of each color (white, red and pink).
Parents.... RW × RW
↓ ↓
Gametes... R, W R, W
Inbreeding...
Progeny.... RR, RW, WW, RW
Hence, 50% of the offsprings will be pink coloured, 25% will be of red color and another 25% will be white color.
