Answer:
Bacteriophage
Explanation:
Bacteriophage is nothing but a virus that harms and kills the bacteria.
The Hershey-Chase Experiments is a well known experiment done by scientist, Alfred Hershey and Martha Chase. They conducted the experiment in the year 1952.
It was an extra ordinary experiment which made the world believe that the DNA is the genetic material and not a protein. In their experiment, they tried to find out if the protein coat or the core of the DNA of the virus which enters into the infected cells would help them to understand whether the genes were made of DNA or of protein.
They used sulfur-35 and phosphorus-32 radioactive isotopes to trace the DNA and the proteins.
Answer:
Explanation:
Hershey and Chase started with a virus called a bacteriophage.
They used the radioactive isotope sulfur-35 to label the protein
of the virus and phosphorus-32 to label the DNA of the virus.
They allowed the tagged virus to infect bacteria and studied the results. Hershey and Chase found that the only radioactive isotope within the bacteria was 32P.
This result indicated that the genetic material inserted by the virus to infect the bacteria was DNA.
Help!! ASAP!! What is asexual reproduction?
Answer:
Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. Many processes or methods are there to form new organism like binary fusion, budding, spore formation etc.
Explanation:
Binary fusion is one of the asexual reproduction. Example: Bacteria, Amoeba.

Does an animal cell have a cell wall?
Answer:Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall
Explanation:
Answer:
No
Explanation:
Animal cells have cell membranes, but not cell walls. Cell walls are much more structured and are only present in plant cells who also have a cell membrane.

A cookie recipe uses 3 cups of flour to make 15 cookies. How many cookies can you make with this recipe with 4 cups of flour. (assume you have enough of the other ingredients.)
Answer:
20 cookies
Explanation:
we are given that
three cups of flour is used to make 15 cookies
3 cups of flour is used to make=15 cookies
one cup of flour will be used used to make 15/3 cookies that will be 5
1 cup of flour is used to make =15/3=5
for 4 cups of flour we will multiply 4 on both sides
hence t will give
4 cup of flour is used to make =5*4=20 cookies
So,
According to recipe 4 cup of flour is used to make 20 cookies
The shape of each of the molecules is important because A) if the shape of any molecule in an organism changes, the DNA in that organism will also change B) the shape of a molecule determines the age of an organism C) the shape of a molecule determines how it functions in chemical reactions D) molecules having different shapes are always found in different organisms
Answer:
The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions
Explanation:
The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.
The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in shape there would be no life existed.
Thus, the correct answer would be - C)

What happens during a convergent: oceanic to continental boundary?
Answer:
When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. ... The subducting plate causes melting in the mantle above the plate. The magma rises and erupts, creating volcanoes

Michael and Jose are studying about plate tectonics. They learned that plates usually move a few centimeters every year. They learned that the movement of heated material caused the plates to move. In which layer does the heated material move?
Answer:
Mantle layer
Explanation:
The movement of heated materials on the mantle layer of the earth helps in the movement of the tectonic plates. The earth is made up of four layers and they are the crust, the mantle, the outer core, and the inner core. The tectonic plates are always in motion which is very slow but constant.
The convection currents emanating from the mantle layer of the earth aids the movement of the tectonic plates. Natural disasters like earthquakes can result from the intense pressure emanating from the movement of the plates.

What happens to the oxygen in respiration?
Explanation:
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
