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.
Kinda like a pyramid. The bottom is wide, many sources of energy (plant life) that take nutrients combine them with water use the bonding of the suns rays and convert that to matter. This matter is then consumed by animals (grazers and browsers), who in turn are fed upon by predators. With man as the top predator.
Take a few seeds from wire-grass. Wire-grass grows in many natural communities, it is eaten by rodents and birds, like Quail. Quail are eaten by snakes, who are eaten by hawks, bobcats, and raccoons.
every time the meal is transferred from one critter to the next, energy is expended in the chase (heat) and capture, and energy is always being used for the animals to survive day by day.
C. this individual is a male since he has X and Y chromosomes
<span>The three groups of amphibians: Frogs, Salamanders, Caecilians are different when they reach adulthood. Frogs have four legs with strong hind legs and no tails. Salamanders have tails and four short, weak legs that cause them to walk instead of jump. Lastly, Cacilians have no legs and are burrowing animals.
Amphibians must live in moist environments because they loose water through their thin skin. They need to be near water to replenish the lost water. Also their skin helps them breathe and they can get oxygen from the water.</span>
