0:3:1
Explanation:
Tasters have the dominant allele for the itter taste of PTC, they can be homozygous TT and heterozygous Tt.
Non-tasters are supposed as autosomal recessive characters
they are homozygous recessive tt when expressed
Given in the equation two heterozygotes parents would produce offspring with the trait in the following ratio.
Tt (parent 1)
Tt (parent 2)
If a punnet square is made
T t
T TT Tt
t Tt tt
The phenotypic character is in the ratio of 0:3:1
There will be 25% chances of recessive trait of non-tasters in the progeny of heterozygous parents.
Prokaryotic cells are simpler than eukaryotic cells. This is because prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells have many chromosomes inside a nucleus, and they also have more organelles.
Answer:
1. Adenine
2. Thymine
Explanation:
These are the four nitrogen bases of DNA nucleotides. It's just something that you have to memorize in order to be able to successfully study DNA. In case you are asked which base pairs with which, always remember this saying about base pairs: A and T, and, G and C.

Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.[5] Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis.
