What else can I help you with?
Which microscope would be used to study a nucleus?
A transmission electron microscope (TEM) would be used to study a nucleus in detail. TEM uses a beam of electrons to visualize the internal structures of cells at a high resolution, making it ideal for studying the fine structures within a nucleus at the molecular level.
Which instruments would best help the scientist determine the results of his study?
Instruments such as spectrophotometers, microscopes, chromatographs, and centrifuges could help the scientist determine the results of their study by measuring chemical concentrations, viewing samples at a microscopic level, separating compounds for analysis, and isolating specific components within a sample.
How much would a nucleus the size of a grape weigh?
A nucleus the size of a grape would weigh virtually nothing, as the vast majority of an atom's mass is contained in its nucleus, which is incredibly tiny compared to the size of a grape.
Where is the proton located in an atom?
In the nucleus of the atom, along with neutrons. The electrons are found around the nucleus. If the atom was the size of a Baseball stadium, the nucleus would be the size of a baseball! Most of the space in an atom is taken up by the electron cloud which surrounds the nucleus. That is why atoms are actually mostly empty space.
How many particles are in the nucleus of an atom of xenon?
For an atom of xenon, the number of particles in the nucleus would be the sum of the protons and neutrons. Xenon has 54 protons and usually around 78 neutrons, so the total number of particles in the nucleus would be around 132.
What microscope do I use to study the internal parts of a cell?
You would typically use an electron microscope to study the internal parts of a cell, as it provides much higher magnification and resolution compared to a light microscope. Electron microscopes can reveal detailed structures inside cells, such as organelles like mitochondria and the nucleus.
What instrument would a scientist use to see a micro-organism?
A microscope would be used to see micro-organisms. Microscopes use lenses to magnify objects that are too small to be seen by the naked eye. There are different types of microscopes, such as light microscopes and electron microscopes, that can be used depending on the size and detail needed to study the micro-organism.
What would be the best tool for looking at cells in a scientific investigation?
A microscope would be the best tool for looking at cells in a scientific investigation, as it enables researchers to visualize cells at the microscopic level and study their structures and organelles. Advanced microscopes, such as electron microscopes, offer higher magnification and resolution for detailed cell analysis.
Which microscope would be used to study a nucleus?
A transmission electron microscope (TEM) would be used to study a nucleus in detail. TEM uses a beam of electrons to visualize the internal structures of cells at a high resolution, making it ideal for studying the fine structures within a nucleus at the molecular level.
How do you increase the contrast between the nucleus and the cell contents using a light microscope?
You can't change the contrast on the microscope, that would have to be done using dyes.
Why are microscope needed to study cells?
Microscopes are needed to study cells because they allow scientists to magnify and visualize cells at a level of detail not visible to the naked eye. This is important for observing cell structure, organelles, and cellular processes. Microscopes also enable scientists to make accurate observations and gather data about cell function and behavior.
What part of a cell would you study if you wanted to observe chromosomes?
Chromosomes are found only in the nucleus of the cell. Although they are actually observed as chromatinthroughout most of the cell's life the chromatin does condense into chromosomes during mitosis/meiosis.
Is it true tha if you see a eukarote cell you can identify the nucleus and several organelles?
Yes, all eukaryotes have organelles and a nucleus, but you just have to have a microscope to see them with. Most light microscopes aren't powerful enough to see organelles other than the nucleus and nucleolus, so you would need an electron microscope too see them.
What do they use to see cells?
Scientists use microscopes to see cells. There are different types of microscopes such as light microscopes, electron microscopes, and fluorescence microscopes, each offering different levels of magnification and resolution to study cells in detail.
What scientific tool would you use to look at something very small like bacteria?
You would use a microscope to look at something very small like bacteria. There are different types of microscopes, such as light microscopes and electron microscopes, that can magnify objects at the microscopic level.
What microscope would be used to study the content of a nucleus?
To study the content of a nucleus, a transmission electron microscope (TEM) is often used. TEM provides high-resolution images at the nanometer scale, allowing researchers to visualize the ultrastructure of the nucleus, including chromatin and nucleoli. Additionally, fluorescence microscopy can be employed to examine specific proteins or DNA within the nucleus using labeled probes.
What differences did microscopes bring to every day life?
ithout microscopes, it would be hard to see bacteria or the planets
