Early microscopes -lenses made images but not clear?
Early microscopes had limitations in the quality of lenses, resulting in unclear images. These lenses were often unevenly shaped and prone to distortion, which hindered the sharpness and accuracy of the images produced. This restricted the ability of early microscopes to provide detailed and precise observations of specimens.
How does a plant and animal cell look?
Plant and animal cells are usually round shaped with arms. It is impossible to see the colours because the microscopes that can go close enough are black and white.
Why weren't cell discovered until 1665?
in 1665 a british scientist robet hooke was looking at a slice of a kork and discovered a honeycomb shaped thing, later he discoved it was a cell
What is refracting glass?
Refracting glass is glass that has been shaped or curved to bend light as it passes through, causing it to converge or diverge. This is used in lenses, prisms, and other optical instruments to manipulate and focus light for various applications such as in microscopes, cameras, and eyeglasses.
What is used cover slip?
The main function of the cover slip is to keep solid specimens pressed flat, and liquid samples shaped into a flat layer of even thickness. This is necessary because high-resolution microscopes have a very narrow region within which they focus.
What is located in the nucleus and controls an organism's physical characteristics in the shape of an X?
You are asking about chromosomes.However the chromosomes in the nucleus of eukaryotic cells are rarely "X shaped", most of the time they are long "thread shaped" objects. They only take on the "X shaped" form during one short period during the process of cell division, after the chromosome has been copied into two identical "threads" but they have not yet been pulled apart in the process of dividing the nucleus itself.You usually only see photographs of the "X shaped" form of chromosomes because this is when the DNA of the chromosome and attached proteins are in the most compact form and easily visible to light microscopes. The "thread shaped" form of chromosomes (in which they actually do their work) is many times longer than the "X shaped" form of chromosomes as it has been "unpackaged" and is really only resolvable by electron microscopes. A photograph of the "thread shaped" form of the chromosomes inside the nucleus (as they are most of the time) would look very much like a bunch of tangled strands of very thin spaghetti.
Can bacteria be linked with a virus?
Bactareia and virus have some thing common and very small in size which are only seen by microscopes. Both are causes a big problem in human being.Bactareia shape like a Spherical, Spiral and Rod shaped. While virus include nucleic acid in itself.
How do some dreaming stories describe how the Australian environment was shaped?

Tools for refracting light are what?
Tools for refracting light include prisms, lenses, and optical fibers. They are used to manipulate the path of light by bending or splitting it, leading to various applications in optics and technology. Prisms, for instance, can break white light into its constituent colors, while lenses are commonly used in cameras and microscopes to focus light.
What did the writers believed?
that humans were shaped by their environment. :)
How do you think the environment has shaped the lives of the people?
You need to define which people and which environment
Give the importance of microscope in studying biology?
The compound light microscope is popular among botanists for studying plant cells, in biology to view bacteria and parasites as well as a variety of human/animal cells.It is a useful microscope in forensic labs for identifying drug structures.With this type of microscope you generally have the choice of purchasing the fixed or zoom variety from a manufacturer and are relatively inexpensive.Uses for this type of microscope include looking at surfaces, microsurgery, and watch making, plus building and inspecting circuit boards.Stereo microscopes allow students to observe plant photosynthesis in action.It connects to a computer monitor via a USB cable, much like connecting a printer or mouse. The computer software allows the monitor to display the magnified specimen. Moving images can be recorded or single images captured in the computer's memory.An advantage of digital microscopes is the ability to email images, as well as comfortably watch moving images for long periods.The popularity of the digital microscope has increased at schools and among hobbyists.Great for hobbyists and kids, it is an inexpensive device with a purchase price usually under $200US.You may even want to check out the portable digital microscopes that are available now as this is an invaluable tool to aid in image sharing and analysis.The Transmission Electron Microscopes and Scanning Electron Microscopes have practical applications in such fields as biology, chemistry, gemology, metallurgy and industry as well as provide information on the topography, morphology, composition and crystallographic data of samples.Among the different types of microscopes and microscopy techiques, scanning probe microscopy used today in academic and industrial settings incorporating those sectors involving physics, biology and chemistry. These instruments are used in research and development as standard analysis tools. Images are highly magnified and are observed as three-dimensional-shaped-specimens in real time. SPMs employ a delicate probe to scan the surface of the specimen eliminating the limitations that are found in electron and light microscopy.
