  • What is another name for the light microscope?
    What is another name for the light microscope?
    The correct answer is not on this list. A light microscope is often called an optical microscope. This is because it uses only lights and lenses to provide a closer view of whatever is put on the slides. You’ve probably used one of these kinds of microscopes; they are the kind given to every middle and high school science class. It’s a good way to get a precursory, up-close view of something. This is also the oldest type of microscope design. It dates back to the 1700s, and it is what a lot of the most famous scientists of that time used to make their big discoveries about cells and small things. However, that doesn’t change the fact that the light microscope is also called the optical microscope.

  • Which of the following identifiers is invalid?
    Which of the following identifiers is invalid?
    The answer to this is C. Type name. This cannot be used as an identifier because it will not be able to communicate its meaning properly. If you truly want an identifier to be recognized, you need to use its parameters and its members. If in case you see the need to use a type name, you should choose a language-independent name as this can make it more identifiable. If this violation is done, do not worry because it can easily be fixed. The type name can easily be changed with a parameter or a member. If you continue trying to use a type name as an identifier, expect that you will get the error message soon enough and you cannot progress.

  • What is a variable?
    What is a variable?
    Variable is a portion of memory to store a determined value. According to its name, it is a value that can vary as per the conditions or the information passed to the program. Typically, a program consists of information that tells the computer what to do and the data (raw fact) that the program uses while running. The data consists of fixed values that never change and variable values (which are usually initialized to "0" or some initial value because the actual values will be supplied by a program's user). Usually, certain data types are define by both constants and variables. Each data type determines and restricts the form of required data.

  • What is odds ratio?
    What is odds ratio?
    1. It is the ratio of incidence in exposed divided by incidence in nonexposedIt is the ODDS of diseas not the INCIDENCE IF risk in exposed = p1, and risk in unexposed = p0 then risk ratio = p1/p0 IF odds of disease in exposed = odds1, and odds of disease in unexposed = odds0 Then odds ratio = odds1/odds0

  • What is the space factor when determining the efficiency of algorithm measured by?
    What is the space factor when determining the efficiency of algorithm measured by?
    The correct answer to this question is A. The space factor when determining the efficiency of algorithm measured by counting the maximum disk space needed by the algorithm. Space complexity is a function describing the amount of memory (space) an algorithm takes in terms of the amount of input to the algorithm. We often speak of "extra" memory needed, not counting the memory needed to store the input itself. Again, we use natural (but fixed-length) units to measure this. We can use bytes, but it's easier to use the number of integers used, the number of fixed-sized structures, etc. In the end, the function we come up with will be independent of the actual number of bytes needed to represent the unit. Space complexity is sometimes ignored because the space used is minimal and/or obvious, but sometimes it becomes as important an issue as time.

  • Which way should you lean in case of a nosebleed?
    Which way should you lean in case of a nosebleed?
    There are a lot of people who still believe that in order to stop nosebleeds, they have to tilt their head backward. This may have worked in the past but studies now show that you have to tilt your head forward. This is to prevent the blood from your nose to go down your throat. Take note that your nose is connected with other parts of your body. You do not want to taste blood as it goes down your throat, right? When you tilt your head forward, this will be effective in making the blood clot so your nosebleed will be stopped easier. You also need to pinch your nose lightly in order to help stop the bleeding.

This type of microscope is widely used in biological applications, it is used for stained or naturally pigmented or high contrast specimens mounted on a glass microscope slide.

  • Which type of microscope has only one lens?
    Which type of microscope has only one lens?
    A simple microscope has only one lens. Little more can be said about it because more interesting capabilities are attached to more complex microscopes including a description of the history of microscopy. Humans have long wishes to see more clearly those items that are extremely small, as well as improving their eyesight when it weakens or fails. It has been known for over 2000 years that glass bends light. Ptolemy noticed this in the 2nd Century BC, and accurately recorded the angles of a stick in the water to within half a degree. But it was either Lipperhey or Jansen in the 1590s who invented the first compound microscope that led to close examination of plant and microber life, etc.
