Questions includes all the interesting and fully explained answers to some very common yet lesser known questions of science.

Why is the Two-Kingdom Classification System Inadequate?

We can easily distinguish a living animal from a living plant in our surroundings. We do not find any difficulty in identifying an animal as long as we see it moving, eating and alive. When it comes to plants, we have an image of a structure having spread out appearance with green parts like leaves in our mind. So, to keep it as simple as it was, Carolus Linnaeus classified all the organisms of the world into two Kingdoms i.e. Plantae and Animalia.

What are Megamasers? Why everyone is so excited about them?

Earlier this year, Hubble Telescope found a Megamaser that was around 100 times brighter than the Maser found in our galaxy i.e. Milky Way galaxy. So, you must be wondering What are Megamasers, How do they look like and Why NASA is so excited about them. Here, we have everything about Megamaser that you should know. Continue reading What are Megamasers? Why everyone is so excited about them?

What are the different Causes of Antibiotic Resistance?

Antibiotic Resistance is a term that appears to be like some super terms used in some science fiction movies. But this term is something of which we should be afraid of because antibiotic resistance and spread of drug-resistant pathogens are one of the most serious and dangerous threats to public health in this 21st century. Continue reading What are the different Causes of Antibiotic Resistance?

What is Eutrophication? What are its Causes & Effects?

With the use of high–yielding varieties of crops, the use of fertilizers and pesticides has increased a lot. Excess fertilizers may mix with surface water and may get drained into water bodies (surface runoff). These fertilizers overstimulate the growth of algae, causing eutrophication, and robbing the water of dissolved oxygen vital to other aquatic life. During the past century, lakes in many parts of the earth have been severely eutrophied by sewage and agricultural and industrial wastes. Continue reading What is Eutrophication? What are its Causes & Effects?

How do cells in Embryo get their Roles to Play?

The cells of an embryo get their roles when they are capable of differentiating autonomously in a neutral environment such as a petri dish or test tube. (the environment is neutral with respect to the development pathway.) This process of giving different roles to embryonic cells is called Cell Specification.
