Answer:
As a result of the Hershey and Chase experiments, scientists believe
that the “transforming principle” is DNA.
Explanation:
Hershey and Chase determined that DNA, not protein, was the inherent material. They resolute that a defensive protein coat was molded everywhere the bacteriophage, but that the interior DNA is what discussed its capability to produce offspring inside a bacterium. Transformation occurs when one bacterium picks up free-floating DNA and incorporates it into its own genome. When scientists first observed this behavior, it seemed that genes were transforming one type of bacteria into another, so they concluded there must be a 'transforming principle' at work.
When this gene mutates to cause a loss or reduction in its function, the cell can progress to cancer, usually in combination with other genetic changes.
Answer:
Triploid egg
Explanation:
Triploid, with three copies of each chromosome. When a diploid sperm fertilizes a haploid egg cell it causes a triploid zygote, which leads to the chromosomalabnormalities in the zygote.
Answer:Mass and Distance
Explanation:
The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses puts on each other. If one of the masses is doubled, the force of gravity between the objects is doubled.
