|
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) |
|

|
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 |
