Answer:
We have bacteria that live on us, and bacteria have bacterial viruses that live on them. These viruses are called bacteriophages . Viruses differ from bacteria in that they are not made of cells, but instead consist of a piece of DNA (or RNA) packed within a protein coat. A bacteriophage attaches itself to a susceptible bacterium and infects the host cell. Following infection, the bacteriophage hijacks the bacterium's cellular machinery to prevent it from producing bacterial components and instead forces them cell to produce viral components.
Answer:
When both parents are carriers for a recessive disorder, each child has a 1 in 4 (25 percent) chance of inheriting the two changed gene copies. A child who inherits two changed gene copies will be “affected,” meaning the child has the disorder.
Explanation:
Answer:
The corect answer is some of the reactants were spilled.
Explanation:
Before the initiation of the reaction the total mass of both reactants is 15.0 grams and after the reaction the net mass of product is grams 12.4grams.
This happens because during the reaction some reactant molecules were spilled which ultimately leads to decrease the mass of the reactant molecule.
The decrease in the amount of the reactant equals with amount of product formed.
