The Hershey-Chase experiment was a key experiment in the field of biolgy that established DNA has the inheritable genetic material between the generations of organisms.

In the hershey-chase experiment, bacterial cultures infected with a virus were agitated in a kitchen blender to detach the phage from the bacteria. This step was followed by centrifugation to separate the phage coats from the bacteria.

The Hershey and Chase experiments showed that the inherited genetic material was DNA (deoxyribonucleic acids). In this experiment, the scientists labelled the DNA molecule with a radioactive isotope of phosphorus.

Centrifugation causes the separation of different components according to their size. So, by blending, they centrifugated the mixture of virus and the bacteria, which separated the viral protein capsule and the bacteria. Later, they found that the virus infected bacteria contains the DNA of bacteria, not the protein.

Hence, bacterial cultures infected with a virus were agitated in a kitchen blender to separate the protein coat of virus from the bacteria.

What are the end products of the electron transport chain?

solong [7]

The end products of electron transport chain are:

Water

Adenosine triphosphate (ATP)

Explanation:

Most of the free energy released during the oxidation of glucose to CO₂ is retained in the reduced co-enzyme NADH and FADH₂, generated during the kreb's cycle.
Electron are released from these co-enzymes and are eventually transferred to an oxygen molecule to form water.
These transfer of electron from co-enzymes to oxygen molecule occurs through a series of protein complexes in the mitochondrial membrane. And the process is termed as Electron Transport Chain.

The large amount of free energy is released during the oxidation of NADH and FADH₂ is used in the production of ATP

What is the evolutionary advantage of the heart having its own electrical system?

SpyIntel [72]

The heart’s electrical system is responsible for making and conducting signals that trigger the heart to beat. These signals cause the heart’s muscle to contract. With each contraction, blood is pumped throughout the body. This happens 24/7 without us having to monitor it all the time so that our heart does not stop.

How does human use of natural resources impact human and animal populations?

Kruka [31]

Answer:

We could use up all of them right away and not have the resources for humans and animals to survive.

Explanation:

Right now, we are using our natural resources at a consistent rate. We sometimes use to many of them in one day. If we continue using up our natural resources at the rate we are right now. We may not have the necessary resources to survive in about 10-20 years.

Hope this helps!

Anthony places a drop of water under a microscope and observes some small objects. He concludes that the small objects are cells

natta225 [31]

Answer:

It depends on the lens of the Anthony´s microscope, but It is likely that he saw artifacts

Explanation:

An optical microscope contains lenses of focal lenght that enable to see different structures. In this case, it is likely that Antony saw artifacts since living cells are not easy to focus with the optical microscope, it requires operator experience

scientists have a theory that is accepted worldwide as the best explanation for the orgin of the universe a group of scientists

kvv77 [185]

It might knock the old theory away completely because all of the new knowledge doesn't support the theory or it could change it because some of the new information supports the old stuff.
