Explanation:
alfred hershey and martha chase designed an experiment to determine the chemical makeup of griffith's transforming principle. define the term bacteriophage and explain why this organism was a good choice for this particular experiment. describe the procedure of the experiment using the terms bacteriophage, DNA, and proteins in your answer. Describe the results of the experiment and connect them to hershey and chases conclusion
Answer:
Bacteriophages (phages) are viruses that infect only bacteria and do not infect mammalian or plant cells. Phages are ubiquitous in the environment. Phages or bacteriophages were chosen as a model system for their simplicity, as they only contained protein-coated nucleic acid. Alfred D. Hershey and Martha Chase (who were part of the bacteriophage group) in 1952 studying the infection of the bacterium Escherichia coli by the T2 phage show that the information definitely resides in the DNA. They used phage with either [32P] -labeled DNA or [35S] -labeled proteins to infect the bacteria. Immediately afterwards, they centrifuged the sample so that the infected bacteria remain in the pellet and the virus capsids (proteins) remain in the supernatant. [35S] is found in the supernatant, whereas [32P] is found in bacteria. After one cycle of infection, it was observed that when phage labeled in the [35S] proteins were used, only 1% of the radioactivity was incorporated into the progeny. But when phages were [32P] labeled, more than 30% of the radioactivity was in the progeny. They showed directly that what is transmitted from one progeny to another is the DNA and not the proteins, despite having first "diluted" in a bacterium.
Explanation:
Bacteriophages are viruses that infect bacteria in a specific way. Bacteriophages, like other known viruses, are found in an intermediate zone between living organisms and inert matter. Bacteriophages bind to the host pathogenic bacterium, introduce their genetic material, replicate inside it and destroy it. Hersey, along with his assistant Martha Chase, used phages because they knew that T2 phages were made up of 50% proteins and 50% nucleic acids and that phages entered bacteria and reproduced. As the progeny carried the same infection traits, the genetic material of this had to be transmitted to the offspring, but the mechanism was unknown. These scientists carried out an experimental work with the T2 virus, a bacteriophage that infects the bacterium Escherichia coli, which it reproduces by attaching itself to the outer wall of the bacterium, injecting its DNA into it where it replicates and directs the synthesis of the phage's own proteins. Phage DNA is encapsulated within proteins and produces phages, which lyse or disrupt the cell and release phage from progeny. They infected a culture of bacteria with radioactively labeled phages: the protein coat with sulfur (35S) and its DNA with phosphorus (32P). After infection, they separated the phages from the bacteria by violent shaking using a mixer (hence the name of the experiment). By centrifugation the much smaller phages remained in the supernatant and the much larger bacteria in the pellet. 85% of the radioactivity corresponding to DNA appeared in the pellet and 82% of the protein in the supernatant. This result supported the idea that DNA was the only component of the bacteriophage that penetrated the interior of the bacteria and, having the ability to form new phages, constituted the genetic material.
why photosynthesis is important
Answer:
It is important because plants would not be able to produce food for themselves, so the plant would die. Animals that feed on plants would not be able to survive, and animals that feed on other animals would die too because they would not have any food.

The graph presents information about the climate of Dallas, Texas.
A graph shows average monthly precipitation and temperature for Dallas, Texas. Temperatures rise from January to July and drop between August and December. Precipitation increases from January to May, decreases in June, July, and August, increases again in September and October, and decreases again in November and December.
Which of the following best describes this climate?
A. warm temperatures and rainy weather all year long
B. warm summers, cold winters, seasonal precipitation
C. seasonal temperatures, little precipitation
D. warm, wet summers; cold, dry winters
Answer:
B
Explanation:
The statement that best describes the circumstance of this given climate is as follows:
Warm summers, Cold winters, and Seasonal precipitation.Thus, the correct option for this question is B.
What is Climate?Climate may be defined as a type of weather conditions that are persuading in any geographical location for a long period of time. In a more simple sense, it is characterized as the long-term pattern of weather in a particular area.
According to the context of this question, the duration between January to July illustrates the rising of temperature which means warm summer.
The duration between August and December, the temperature falls down consistently and gradually which means cold winters.
The months of January to May and September and October represent seasonal precipitation. According to the graph, it understands that the monsoon season comes twice a year with high precipitation.
Therefore, the correct option for this question is B.

If a mosquito cell has 3 chromosomes, is it haploid or diploid?
Answer:
If an orangutan cell had 24 chromosomes, then the cell is diploid or haploid (circle one). If a mosquito cell had 3 chromosomes, then it would be a gamete or a somatic cell (circle one).
mark me as brainlist please
All mosquitoes have six diploid chromosomes (2N = 6), and their chromosomes are either submetacentric or metacentric, mosquito cell has 3 chromosomes and is haploid.
What is the difference between haploid and diploid?Three pairs of chromosomes make up the Anopheles mosquito's chromosomal complement: two sex chromosomes As a consequence, when a sperm and egg cell join during fertilization, the resultant zygote has 46 chromosomes.
The number of chromosomes and their shape in mosquitoes are extremely similar mosquito cell has 3 chromosomes, and are haploid.
Therefore, to go from haploid to diploid cells, we only need to double the number of chromosomes. This quantity is denoted by the abbreviation 2n, where n is the number of chromosomes.
