A dialysis machine tries to mimic some of the functions of a human kidney. One of the primary jobs of a kidney is to remove urea and certain salts from the blood so they can exit the body in urine. In a dialysis machine, blood from the patient runs through tubes made of a semi-porous … Read more DMPQ-Explain the functioning behind the working of dialysis machine.

In the category of natural food preservatives comes the salt, sugar, alcohol, vinegar etc. These are the traditional preservatives in food that are also used at home while making pickles, jams and juices etc. Also the freezing, boiling, smoking, salting are considered to be the natural ways of preserving food. Coffee powder and soup are … Read more DMPQ- What are Natural Food Preservatives?

In order to form a zygote, male gametes in pollen grains have to fuse with egg in the ovule. This is achieved by the process called pollination. Pollination is the process of transferring pollen grains from the anther – male part of a flower, to the stigma – female part of a flower. Depending on … Read more DMPQ- Define pollination and its types.

:  Nitrogen is the most abundant gas in the atmosphere and it is in inert form. But when it converts into reactive form like ammonia, nitrous oxide and nitrogen di oxide, it become dangerous for the ecosystem in many ways. Nitrogenous gases also play an important role in global climate change. Nitrous oxide is a particularly … Read more DMPQ: Nitrogen pollution is more dangerous than carbon pollution. How nitrogen affects our ecosystem. (Science)

  Nanotechnology is improving the efficiency of fuel production from raw petroleum materials through better catalysis. It is also enabling reduced fuel consumption in vehicles and power plants through higher-efficiency combustion and decreased friction.  carbon nanotube “scrubbers” and membranes to separate carbon dioxide from power plant exhaust. Development of wires containing nano tube that will … Read more DMPQ: . Application of nanotechnology in the field of Energy application. (SCIENCE)

It is a technology to bring the changes in the phenotype(the way we appear) by altering the genome. The insertion of foreign gene and thus creating new gene is called recombinant gene. The technology involved in the process is called rDNA technology. Steps in the rDNA technology are: Identification Of donor DNA and Plasmid DNA. … Read more DMPQ: What is recombinant DNA technology? Mention the steps involved in rDNA technology? (Science)

.  AVATAR is a single-stage reusable spaceplane capable of horizontal takeoff and landing, being developed by India’s Defense Research and Development Organization along with Indian Space Research Organization and other research institutions; it could be used for cheaper military and civilian satellite launches. According to the Designers, Hyperplane projects of the 1980’s – the X-30, … Read more DMPQ- What is AVATAR (Aerobic vehicle for hypersonic aerospace transportation) ? Discuss it’s signicance in boosting India’s defence.

Noncommunicable diseases (NCDs), also known as chronic diseases, tend to be of long duration and are the result of a combination of genetic, physiological, environmental and behaviours factors. The main types of NCDs are cardiovascular diseases (like heart attacks and stroke), cancers, chronic respiratory diseases (such as chronic obstructive pulmonary disease and asthma) and diabetes. … Read more DMPQ: India is becoming a hub for non communicable diseases? Suggest the way to deal with the menace of non communicable disease.

Mendel’s laws Mendel discovered that, when he crossed purebred white flower and purple flower pea plants (the parental or P generation), the result was not a blend. Rather than being a mix of the two, the offspring (known as the F1 generation) was purple-flowered. When Mendel self-fertilized the F1 generation pea plants, he obtained a … Read more DMPQ: Describe in brief Mendel’s Experiments and law of inheritance

Project Beehive was launched by the Army’s Corps of Electronics and Mechanical Engineers(EME) on September 1,2019. The project seeks to achieve greater automation of the Corps and connect all its workshops to an integrated smart network with real-time data analytics capabilities.The centralised network would allow Indian army to access data about any equipment across the … Read more DMPQ- Write a short note on Project Beehive.
