Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks.
What is Hershey and Chase experiment?They discovered that nearly all the radioactivity was found in phosphorus, confirming that DNA contains genetic material, not protein.
The final experiment, also known as the Waring Blender experiment, in which Hershey and Chase demonstrated that phages only injected their DNA into host bacteria and that the DNA acted as the replicating genetic element of phages, is the Hershey-Chase experiment that is most well-known.
Hershey and Chase discovered proof that phages introduced their DNA into host bacteria in the prior experiment.
Therefore, Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks.

90% H2O 10% Solute The solution is: hypertonic / hypotonic / isotonic Water will: not move / move into the cell / move out of the cell
Answer:
Hypotonic / moves into the cell.
Explanation:
Hope you have a nice evening.
The solution is hypotonic. Water will move into the cell.
What is hypotonic solution?A hypotonic solution is one where the concentration of solutes outside the cell is lower than the concentration inside the cell. In this case, the solution is composed of 90% water and 10% solute, which is a lower concentration of solutes than inside the cell.
As a result, water will move into the cell in order to balance the concentration of solutes and maintain homeostasis. This can cause the cell to swell and may even lead to lysis if the cell is unable to handle the increased volume.

What 3 systems get put to work when a beaver is building a home and how?
Answer:
beaver dams smooth out water flow by increasing the area wetted by the stream. This allows more water to seep into the ground where its flow is slowed. This water eventually finds its way back to the stream. Rivers with beaver dams in their head waters have lower high water and higher low water levels.

which laboratory tools are useful when looking at internal organs of an earthworm
Answer:
An earthworm's internal organs can be viewed through a dissecting microscope. This type of microscope allows enhanced observation of objects that are too large for a compound microscope. Because the magnification is low, this microscope cannot be used to examine cells.

Rebecca’s family uses their house’s heating system to stay warm in the winter. How do they know when their system is at equilibrium?
A. The house temperature balances the set temperature and the system shuts off.
B. The house temperature is changing and the system is rapidly changing from on to off then back again.
C. The house temperature is lower than the set temperature and heat is on.
D. The house temperature is higher than the set temperature and the cooling is on.
Thank you.
Answer: A
Explanation:
Answer:
A. The house temperature balances the set temperature and the system shuts off.
Explanation:
Equilibrium is a state in which the competing factors of a system are in balance. In the case of the heating system, the house temperature and set temperature would be the same and the system would turn off.

Hello! I have to write an essay based on the Water Cycle and what it is/does. I will give Brainliest for the correct answer. I will also give 20 points to whoever writes the essay, and has the correct answer. Good luck.
Answer: The water cycle also known as the hydrolic cycle describes the always foward rotation above and below the surfaces of the earth. The mass of water on earths surface remains fairly consistant. However, the water splits up into diffrent groups, freshwater, saline water, ice, and atmospheric water. The water can travel between catorgories such as river to ocean or ocean to atmosphere through evaporation, condensation, precipatation, surface runoff and subsurface flow. When water go through these physical process it can change aswell such as being a liquid, solid,and gas. During evaporation it takes water from it surroundings and cools its enviromwnt,
the exchanges in heat fluctuate the climates tempature.

How does DNA send it's instructions to the other parts of the cell?
Answer:Through mRNA, the DNA is able to transmit its messages out to other parts of the cell. (Learn more about mRNA here.) Information from the DNA is coded into mRNA which leaves the nucleus of the cell DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies (the white region) and is used by ribosomes (outlined in green). hope this helps have a great night ❤️❤️❤️

Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.

C:The number of individuals that must exist for a species to continue.
Answer:
The number of individuals that must exist for a species to continue
Explanation:
I just had it on a quiz. Can I have brainliest?
The critical mass of a species is the number of individuals that must exist for a species to continue. Therefore, the correct option is C.
What is the critical mass of a species?The critical mass of a species refers to the minimum number of individuals that are required for a population to maintain its viability and continue to survive and reproduce in a given environment. This is also known as the minimum viable population (MVP) size.
The concept of critical mass is important in conservation biology because small populations are often more vulnerable to extinction due to genetic factors, environmental fluctuations, and other factors.
Therefore, understanding the critical mass of a species is significant for determining appropriate conservation strategies and protecting endangered species. Therefore, the correct option is C.
