what was the key factor that allowed Hershey and Chase to show that DNA alone carried the genetic information of a bacteriophage?

Answers

Explanation:

DNA contains phosphorus, but protein does not. Protein contains sulfur, but DNA does not. This allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

[tex] \mathbb \fcolorbox{green}{red}{ STAY \: STRONG}[/tex]

[tex] \mathfrak \fcolorbox{green}{red}{BE \: BRAINLY }[/tex]

In the DNA  structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

What is Hershey and Chase experiment?

Hershey-Chase experiment was the final experiment which is also called as the Waring Blender experiment. In this experiment, they showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages.

They used this experiment to prove that DNA is the genetic material. [tex]T_2[/tex] Bacteriophage that was grown in isotopic medium radioactively labels a specific viral component. Two types of isotopic media were used.

Viruses that were grown in radioactive sulfur (35S) contained radiolabeled proteins.Viruses grown in radioactive phosphorus (32P) had radiolabeled DNA

Next, the virus was allowed to infect a bacterium (E. coli) and the virus and bacteria were then separated through centrifugation. After centrifugation, the larger bacteria formed a solid pellet, while the smaller viruses remained in the supernatant. The pellet of bacteria was found to be radioactive when infected with 32P-virus (DNA), but not with 35S-virus (protein).

This provided proof that DNA was the genetic material because DNA had been transcribed into bacteria, not proteins.

Thus, in the DNA  structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

I need help on 3 Factor that affects population thingy. I don’t understand anything :(.

Answers

Answer:

Population growth (I think because birth rates, death rates affect populations)

Dispersion: There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion.

example question: "Describe the types of population dispersion, with examples, and the factors that influence them."

(I'm using this as a example to explain dispersion)

(things that affect dispersion) - Water supply, climate, shape of the land, vegetation, soils and availability of natural resources. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, pine trees. (or any forest)

Explanation:

Birth rates are a major factor because it is a continuous way for a population to grow, if you have low birth rates and high morality (Death rates) a population wont be balanced and death would largely out number the morality rate and time span of a population. That being the older population dies quickly because there is no younger populations to help them. This can lead to extinction too. Immigration is a population or group moving to the current one, it impacts population because its a very large group of new species being introduced to the current one adding numbers. This can also be bad because some immigrated species could be invasive and kill or take over the current/native species.

Example:

Algae blooms can reduce the ability of fish and other aquatic life to find food.

Individuals, as well as industry—and automobile manufacturers in particular have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere. Agree or disagree

Answers

Agree because we need to look ahead into the future. We may have a normal life with not much negative effects but the future generations to come will. Plants will die causing animals to die with them. Good will become scarce and oxygen in the atmosphere will decrease.

It is right that individuals, as well as industry—and automobile manufacturers, in particular, have an obligation to work to reduce carbon dioxide emissions that may increase the level of greenhouse gases in the atmosphere.

Carbon dioxide is a greenhouse gas, which means that it traps heat in the atmosphere. This can lead to climate change, which is already having a number of negative effects on the planet, such as rising sea levels, more extreme weather events, and changes in plant and animal life.

Individuals can reduce their carbon dioxide emissions by making changes to their lifestyle, such as driving less, using less energy at home, and eating less meat. Industry can reduce their carbon dioxide emissions by investing in new technologies, such as renewable energy and energy efficiency.

Automobile manufacturers have a special responsibility to reduce carbon dioxide emissions, as cars are a major source of greenhouse gases. They can do this by designing more fuel-efficient cars and by using alternative fuels, such as electric and hybrid cars.

It is important for everyone to do their part to reduce carbon dioxide emissions. By working together, we can help to protect the planet for future generations.

Why a cell spends the majority of its time in interphase.

Answers

A cell spends the majority of its time in interphase because during this period the cell grows and synthesizes materials required during and after its division. During interphase, the cell duplicates its genetic material.

The cell cycle can be divided into a long interphase and a short mitotic (M) phase.

The interphase can in turn be divided into three phases: Growth 1 (G1) phase,  Synthesis (S) phase and Growth 2 (G2) phase.

During the S phase, the cell duplicates its genetic material, which is sharply controlled by different cellular mechanisms (e.g., checkpoint mechanisms).

During G1 and G2 phases,  the cell synthesizes all the proteins required during the M phase and after cell division.

which disease is caused when there isn't enough bile to breakdown fat and oil in food . And how is it caused​

Answers

Exocrine pancreatic insufficiency (EPI) causes problems in how you digest food. Your pancreas doesn't make enough of the enzymes that your body needs to break down and absorb nutrients. Enzymes speed up chemical reactions in your body. The enzymes made by your pancreas move into your small intestine, where they help break down the food you eat. When you have EPI, you don't get the nutrition you need because your body can't absorb fats and some vitamins and minerals from foods. You might lose weight or have pain in your belly.

Answers

Given what we know, we can confirm that both gamma rays and x-rays can be used to slow the decay process in foods.

What are gamma rays and x-rays?Both of these are forms of ionizing radiation. Applying these to food is known as food irradiation. What this accomplishes, is that the food that is irradiated will have its chemical bonds altered, slowing the decay process.

Therefore, since both gamma rays and x-rays offer ionizing radiation to the food, which affects the chemical bonds and allows the food to have a longer shelf life, we can confirm that they can be used to slow the decay process in foods.

How are seeds produced

Answers

Answer:

From other seeds

Explanation:

They grow more seeds form the one seed

Answer:

From plant reproduction.

Explanation:

Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.
