Describe the compound light microscope
magnification:5x1000x
How it works/discription:*made of a tube with lenses stage, and a light
*specimen is placed on the stage, light passes through, and the lenses magnify
Uses:*To observe things that are too small to see with the naked eye.
*Looking at pond, water, blood samples, tissue samples (living things)
How are the images created by electron microscopes different than compound microscopes?
Electron microscopes are abl to see up to 200,000 x and provides clear highly magnified images which are none living samples where the compound light microscope magnifies 5x 1000x and observes pond water, blood samples and only living samples
Describe the MRI(magnetic resonance image)
How it words: *Use short bursts of magnetic field
Uses:*Brain/spinal tissue images
*to see tears in soft tissue
*diagnosis of medical conditions

What is the deffinition of Life Science
Life science is the study of living things. The main themes are: To see how orginisums grow and how they function, to find cures, combating disease, inherited diseases, and protecting the enviorment
Describe the Scanning electron microscope
Magnification: up to 100,000x
How it works/description: *Electrons bounce off surface of the speicmen. * A 3D image is produced
Uses: *Provides clearer pictures of surface features (NONE living samples)
Which type of microscope would a scientist use if he or she wanted to look at LIVING organisms in a drop of pond water? (explain)
A compound light microscope because it observes living samples such as pond water
Describe the Computer
Year Invented:1946 (first electron computers)
Uses:* collections, storage, prginisums, and analysis of imformation
*Creating of graphs, solving complex mathematicle problems, share data/information with other scientist
List Some key words in the quiz
Scientific method(all 6 steps), question, hypothesis, research, conclusion, data, observation, independent variable(goes on the x axis), dependent variable(goes on the y axis), control(s)
Describe the CT scan(computed tomography)
How it works:*Low dosage x-ray beams pass through body at different angles(dye is injected to highlight tissues)
Uses:*Brian/spine tissue images
*Show body clots
*Diagnosis of medical conditions
Which of the tools(s) mentioned above provided the clerer images
CT scans and MRI's
Describe the X-ray
How it works: *Beams of electrons(radiation) are used to form an image
Uses: *Used to see internal industry analyst of chemicals (bones, heart, lungs)
*Used to learn about protein structure
Describe the Transmission electron microscope
Magnification:up to 200,000 x
How it works/description:*Tiny particles called electrons are used to produce magnified images
*A flat image is produced
Uses: *Porvides clear highly magnified images (NONE living things)
Describe the Computer
Year Invented:1946 (first electron computers)
Uses:* collections, storage, prginisums, and analysis of imformation
*Creating of graphs, solving complex mathematicle problems, share data/information with other scientist
