What do you like and do not like about biology


This sounds like a test question, that only you can answer.

Biology is the science otherwise known as what makes living things alive. If you wanted to be a doctor, or police technician, or a farmer, biology will be very important. Since biology is about learning what makes living things alive, and since living things constantly change, the knowledge of biology will also need constant use and improvement. Doctors, dentists, and dermologists rely on their knowledge of biology to determine whether their patients can undergo various procedures for their health. Police technicians rely on knowledge of biology to develop microscopic physical evidence to solve crimes, and develop better detection tools to defeat clever criminals. Farmers need to know how to treat a fungal attack in crops and livestock, and buyers of their products need to know about soil and environmental conditions in the growing area. Astronauts, athletes, actors and soldiers need to be protected from contaminating agents and conditions that take advantage of new environments to cause illness.

It all starts with long classes in the details of what makes cells, bacteria or viruses tick, with lots of terminology. Whether you like biology or not for its own sake, the your liking will probably be based on your goals, what do you want to do? Knowledge of biology can be applied in many careers, and as long as you have that goal in mind, the long boring classes will soon be exchanged for a meaningful living.

So it's back in your court. Good luck and congratulations for choosing a fine career.

Define biology


You can find a nice definition here: http://en.wikipedia.org/wiki/Biology

According to bing's dictionary:
1. science of life: the science that deals with all forms of life, including their classification, physiology, chemistry, and interactions 2. life in one place: the forms of life in a particular environment and their behavior, development, and history "the biology of desert regions" 3. particular organism's makeup: the structure and functioning of a particular organism "the biology of the fruit fly" [ Early 19th century. Via French Biologie bios "life" ] link: http://www.bing.com/Dictionary/search?q=define+biology&qpvt=define+biology&FORM=DTPDIA

What is the function and the purpose of the parts of the microscope ?


Starting at the bottom of the Compound Microscope scope working up: The base of the scope houses the illumination system and the field lens. It also provides weighted stablility.
The field lens is where the light comes out of the base. This lens focuses the light from the bulb directly into the substage condenser.
The arm of the scope supports the rest of the scope.
Directly above the field condenser is the substage condenser. The substage condenser collects the light and condenses it further into a more concentrated beam of light. With the substage condenser you can control the amount of light and to some degree the defraction of light. This is helpful in adjusting the "contrast" in the image.
Working up, you find the "stage" which is a platform to support the specimen. The stage may or may not have a specimen holder and a set of specimen holder control knobs.
The magnifying lenses are called the objectives. They look like barrels pointing down at the stage. These are usually marked 4x, 10x, 40x, and 100x. These magnifications are further multiplied by the power of the eyepieces which are usually 10x. So, when using the 4x you are actually seeing the specimen at 40x and when you are using the 10x objective you are actually seeing the specimen at 100x and so on. The 4x is used to "scan" the specimen so that you can find the most interesting area and then focus in further on that region. It is very hard to find exactly what you want to focus in on starting with the higher magnifications. Always start with the low magnifications, 4x or 10x.
The objective lenses are mounted on a rotating turret for easy selection.
Moving on up the scope is the head. It is comprised of the eye tube and the eyepiece. If you have two eyepieces your scope is referred to as a "Binocular Compound Microscope". If you have only one eyepiece, your scope is a "Monocular Compound Microscope".

My microscope won't focus, i tried everything...i don't know what is wrong with it...it's brand new.. it worked a couple times but now it just stopped.. i dont know what brand it is...all it says is...


If your stage is still in its correct orientation then make sure your objective lenses are screwed in tight as well as the eye piece being secured correctly. Try using different objectives (don't go too high or you may damage your lenses if you ram it into your specimen) and using the fine and course focus. If the you still cant focus using different objectives it's quite possible that your mirrors or lenses inside the microscope have been knocked loose. I would then recommend only having it repaired by a certified microscope technician. If it is still under warranty take it back to the store of purchase or send it back to the manufacturer.
