Best way to study Biology is to study with an expert Biology Tutor either online or in-person. You can register with online tutoring service providers and start learning biology online.

Biology means the science of life or a study of living organisms which is divide into many fields in which biology can be used such as in education , laboratory and many more . The Biology laboratory is a facility to users for the preparation and characterization of biological experiments.

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.

get a uninstallation software like revo uninstaller and uninstall the previous installation.

the reason for the problem you are getting are the registry entries that are present for the previous installation.

use advance feature in uninstaller that will remove or display the entries ,remove them and you are good to go

In mathematics, a division is called a division by zero if the divisor is zero. Such a division can be formally expressed as a / 0 where a is the dividend. Whether this expression can be assigned a well-defined value depends upon the mathematical setting. In ordinary (real number) arithmetic, the expression has no meaning, as there is no number which, multiplied by 0, gives a (a?0).
In computer programming, an attempt to divide by zero may, depending on the programming language, generate an error message or may result in a special not-a-number value (see below).
Historically, one of the earliest recorded references to the mathematical impossibility of assigning a value to a / 0 is contained in George Berkeley's criticism of infinitesimal calculus in The Analyst; see Ghosts of departed quantities.

i suggest to buy a legit copy and use the serial that comes with that
