under the microscope. When he had observed the slide 'A' he noticed a large vacant space in the
cells and a dense round body located at one side of the cell. When he had observed the slide 'B',
there was no vacant space in the cell and he noticed a dense round body in the centre of the cell.
a) Identify the type of cell 'A' and 'B'.
b) Name the round dense structure seen in the cell.
c) Write the function of the round dense structure that he observed in the cell.

Answers

Answer:

The correct answer is -

a) A plant cell B animal cell

b) nucleus

C) Vacuole

Explanation:

In plant cells, there is a large vacant space present in the center which is actually a vacuole that plays role in various types such as nutrients storage, water balance. In plant cells, a dense round structure present at one side of the cell known as the nucleus.

In animal cells, the vacuoles are absent or very small however the round dense structure of the nucleus is present in the center of the cell. Thus, the correct answer is -

a) A plant cell B animal cell

b) nucleus

C) Vacuole

ASAP! 30 POINTS!!! Write a persuasive paragraph that argues either for or against wind energy. Be sure to include both the pros and cons of wind energy in your paragraph. Use all data, evidence and examples that you are aware of in your paragraph.

Explanation:

ᴍᴀʀᴋ ᴀs ʙʀᴀɪɴʟɪᴇsᴛ

Answer:

Wind energy is one of the most commonly used types of renewable energy. and also happens to be one of our fastest-growing sources of electricity. However, while there are a number of environmental benefits to using wind energy, there are some downsides. On the pros side, wind is a clean, renewable energy source, and is one of the most cost-effective sources for electricity. On the cons side, wind turbines can be noisy and unappealing aesthetically, and can sometimes adversely impact the physical environment around them. Similar to solar power, wind power is also intermittent, meaning that turbines are reliant on weather and therefore aren’t capable of generating electricity 24/7. Unlike coal, natural gas, or oil, generating electricity from wind doesn’t result in greenhouse gas emissions. While there are some environmental considerations that come with building large wind farms, once operational, wind turbines themselves don’t require burning any fossil fuels to operate.

Additionally, wind energy is completely renewable and will never run out. In opposition to traditional fossil fuels resources that replenish very slowly, wind naturally occurs in our atmosphere, and we don’t have to worry about supply issues in the future.

As far as upfront costs go, wind farms or individual turbines can be expensive to install. However, once up and running, operating costs are relatively low; their fuel (wind) is free, and the turbines don’t require too much maintenance over the course of their lifetime.

A wind turbine’s effectiveness in generating electricity depends on the weather; thus, it can be difficult to predict exactly how much electricity a wind turbine will generate over time. If wind speeds are too low on any given day, the turbine’s rotor won’t spin.  

This means wind energy isn’t always available for dispatch in times of peak electricity demand. In order to use wind energy exclusively, wind turbines need to be paired with some sort of energy storage technology.

One of the biggest downsides of wind energy is the noise and visual pollution. Wind turbines can be noisy when operating, as a result of both the mechanical operation and the wind vortex that’s created when the blades are rotating. Additionally, because wind turbines need to be built up high enough to capture a good amount of wind, the turbines can often interrupt otherwise scenic landscapes, such as mountain ranges, lakes, oceans, and more.

What is Periodic table?

The periodic table is also called the periodic table of the elements which is defined as the arrangement of rows and columns of the chemical elements widely used in chemistry, physics and other sciences and usually represented by chemical symbols.

The elements of the periodic table are classified into groups based on the chemical and reactive properties of the elements where the three major groups are metals, nonmetals and metalloids. The metals in the left and bottom parts of the table give up electrons in chemical bonds.

Thus, in the periodic table, elements are classified as metals, nonmetals, and metalloids according to their properties and their specific location within the periodic table.

Natural selection is the process through which populations of living organisms adapt and change their needs as per nature.

The given statement gives the idea of adaptation rather than natural selection. Natural selection gives the idea of competing for limited resources. Natural selection always leads to the most favorable types of variation that an individual possess.

shrivel.

Answers

Answer:

When a person receives fluids intravenously (through an IV bag, for example), a saline solution is sometime used. Giving large amounts of pure water directly into a vein would cause your blood cells to become hypotonic, possibly leading to death.

Explanation:

The answer is B: It swells.

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Describe the results of the experiment and connect them to hershey and chases conclusion

Answers

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.
