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 . This result indicated that the genetic material inserted by the virus to infect the bacteria was DNA .
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.

Answer:Natural selection works to change populations by favoring some variations in individuals and working to eliminate other variations in individuals. Natural selection is basically a culling process.Apr 2, 2018
Explanation:
The branch of science which deals with genes and inheritance is called genetics.
The correct answer is C.
Adapting in an environment changes in order to survive in a system is called natural selection. The key factor for natural selection is the variation that leads to the change in the genotype of the population.
According to the question, the correct answer is C because the changed and evolved traits must be transferred to the next generation to have better chances of surviving.
Hence, the correct answer is C. The likelihood that traits of organisms are passed on

What kind of material is transported through osmosis?
Answer: water
Explanation: Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water.

Cells store waste in ________.
Answer:
Vacuoles
Explanation:
Cells store waste in organelles called "lysosomes." Thus, the complete statement is "Cells store waste in lysosomes"
Where do cells restore waste?Lysosomes are membrane-bound organelles found in cells. They contain digestive enzymes that can break down various types of biological molecules, including waste materials.
Lysosomes play a crucial role in cellular waste management and recycling processes.
They are responsible for breaking down and recycling cellular waste, unwanted materials, damaged organelles, and foreign substances that enter the cell. By storing waste and containing the digestive enzymes, lysosomes help maintain cellular cleanliness and proper functioning.

Which of the following are not true of exocytosis? A.it occurs at the cell membrane B.it does not require energy C.it needs a vesicle to move the matter D.it expells matter out of the cell
Answer:C is wrong exocytosis only needs a transport protein and atp
Explanation:
The statement which is not true is it needs a vesicle to move the matter. Thus, option C is correct.
What is cell?
Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.
Basically,cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.
The unicellular animals are made up of single cell and all the functions carried out in a single cell like amoeba and multicellular organisms are made up of multiple cells and there is specific cell for specific functions.
Therefore,The statement which is not true is it needs a vesicle to move the matter. Thus, option C is correct.

Meiosis I is often referred to as reduction division because it results in the reduction of the chromosome number from diploid to haploid. The chromosomes that remain in each cell are made of sister chromatids. During meiosis II, what will happen to the sister chromatids?
Answer: they will separate into different cells.
Explanation:
They separate into 4 cells.
Sister chromatids separate during meiosis II, resulting in haploid cells with non-duplicated chromosomes.
What is sister chromatid?A sister chromatid is two identical copies of a chromosome formed by DNA replication, with both copies joined together by a common centromere.
To put it another way, a sister chromatid is 'one-half' of a duplicated chromosome. A dyad is a pair of sister chromatids.
Meiosis II is analogous to mitosis. There is, however, no "S" phase. Because of recombination, the chromatids of each chromosome are no longer identical.
Meiosis II separates the chromatids, resulting in two daughter cells with 23 chromosomes (haploid), each with only one chromatid.
Thus, during meiosis II, there will be the separation of the sister chromatids.
