After mixing a heat-killed, phosphorescent (light-emitting) strain of bacteria is mixed with a living, non-phosphorescent strain. further observations of the mixture show that some of the living cells are now phosphorescent. which of the following observations would provide the best evidence that the ability to phosphoresce is a heritable trait?

Phosphorescence in descendants of the living cells.

Explanation:

The DNA acts as the heritable molecule that pass down from the parents to their offsprings and move from one generation to the next generation.  Different experiments had been done to identify the heritable molecules.

In an experiment, non fluorescent become fluorescent when mixed with the dead fluorescet cells. This means the material has been transformed to the non fluorescent cells. The phosphorescent acts as the descendants in the living cells and may be inherited to the future generations as well.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.

bacteria could be both, harmful and to us. harmful bacteria could make us sick and probably even by getting the chances of getting a disease, but good bacteria fight it off with your immune system. there is always bacteria everywhere we go. we need to make sure to wash our hands after using the restroom, before eating, after eating, after petting an animal too. so you see, bacteria is everywhere and is harmful or . i hope this . : ) : ) : )
