why microscopes are useful in the study of cell biology

Microscopes being invented has opened up a whole new dimension in science. By using microscopes scientists were able to discover microorganisms and study the shape cells and see what small part of plants and animals look like. Today microscopes are used as a tool to diagnosis illness in hospitals and clinics all over the world

since their invention, microscopes have been moved beyond the visible light refracting lenses. Electrons, x-rays and infrared rays are used by far more expensive microscopes to detect even the smallest structures. scanning electrons microscopes are able to resolve viruses, which are far smaller then any cell.

 

 

How Lichens can be environmental indicators.

Lichens are great for environmental indicators because they sense air pollution as well as the concentration of sulfur dioxide in the atmosphere. Lichens are plant organisms that can be found in different exposed places such as tree barks and rocks they are also good at absorbing water and nutrients to grow there.

WAYS TO CLEAN THE AIR

1. try to cyclic or walk to nearby places

2.get ride of your car and use public transport .IE. bus, metro

3.start planting trees to help get ride of co2 editions

4.conserve energy

5.electrical generations is a source of air pollution so conserve electricity

6.conservative electricity by turning of lights in used rooms

7.use less energy by using cold water when ever possible

8.use fans instead of air con

9.reduce, reuse, then recycle

10.buy and use recycled products

11.when barbecuing, use an electric or chimney-type charcoal starter instead of lighter fluid.

12.Use a propane grill when barbecuing

13.drive less in big and fuel wasting cars

14.Maintain your car; it’ll last longer

15.Make sure your tires are properly inflated – you can save $130 a year in gasoline costs

  • Trade your car in for a newer model – newer cars are more efficient and pollute less
  • Don’t “top off” your gas tank – by stopping at the click, you will reduce fumes that contribute to ground-level ozone pollution
  • Avoid idling – in general, turning off and starting an engine uses less gasoline than letting it idle for more than 30 seconds
  • Turn the car off while waiting in line at railroad crossings and drive-thru windows
  • Make sure your car’s air conditioner is working properly – leaky air conditioners in cars are the single greatest source of chlorofluorocarbons (CFCs), a greenhouse gas
  • Clean the condenser coils on your refrigerator every few months – you can reduce electricity consumption 6% or more
  • Use your fireplace less
  • Prevent fires
  • Insulate your home to use less energy
  • Use electric or manual lawn and garden equipment instead of gas-powered equipment
  • Use latex paint to reduce fumes and clean it up with water
  • Use brushes or rollers for painting instead of sprays
  • Keep dust down when digging or moving earth
  • Garden organically
  • Plant low-maintenance landscaping
  • Stay on paved roads whenever possible – driving on dirt roads raises dust which contributes to haze and airborne particulate matter
  • Caulk and weather strip doors and windows
  • Ask your local Solid Waste District where to take leftover and unwanted paints, automotive fluids and household chemicals.
  • Go solar for home and water heating – it reduces the need to burn fossil fuel
  • Compost – you’ll use less chemicals in your garden
  • Look for durability in products you buy and use, not just lower price
  • Call the Air Quality Complaint Hotline (513-946-7777) to report odor, dust, smoke complaints.
  • Share this information with others.
