HCA Study Material: 25 Important Previous year Solutions (25 പരിഹാരങ്ങൾ)
- Correct Choice : B) Antoine Lavoisier
Solutions : Antoine Laurent Lavoisier is consider as the Father of Chemistry. He was a meticulous experimenter, he revolutionized chemistry. He established the law of conservation of mass, determined that combustion and respiration are caused by chemical reactions with what he named “oxygen,” and helped systematize chemical nomenclature, among many other accomplishments. Lavoisier wrote the book Elements of Chemistry (1787). He compiles the first complete (at that time) list of elements, discovered and named oxygen and hydrogen, helped develop the metric system, helped revise and standardize chemical nomenclature and discovered that matter retains its mass even when it changes forms.
Another popular choice for the title of Father of Chemistry is Jabir ibn Hayyan, a Persian alchemist living around 800AD who applied scientific principles to his studies.
- Correct Choice : D) It must have a constant velocity
Solutions : If speed is constant, particle may still have an acceleration. e.g. in uniform circular motion, speed is constant but as the direction of motion changes continuously, velocity changes and there is acceleration.
- Correct Choice : C) Hydrogen
Solutions : Hydrogen will be the odd one out because argon, helium and neon are Inert ( noble ) gases.
- Correct Choice : A) Kidney
Solutions : Nephron, functional unit of the kidney, the structure that actually produces urine in the process of removing waste and excess substances from the blood. There are about 1,000,000 nephrons in each human kidney. The most primitive nephrons are found in the kidneys (pronephros) of primitive fish, amphibian larvae, and embryos of more advanced vertebrates. The nephrons found in the kidneys (mesonephros) of amphibians and most fish, and in the late embryonic development of more advanced vertebrates, are only slightly more advanced in structure. The most advanced nephrons occur in the adult kidneys, or metanephros, of land vertebrates, such as reptiles, birds, and mammals.
- Correct Choice : B) i, ii and iii only
Solutions : Photosynthesis , Microbial decomposition , Formation of fossil fuels are part of the carbon cycle in an ecosystem
- Correct Choice : C ) Liver
Solutions : Your liver gets blood from two distinct sources: the hepatic artery and the portal vein. Oxygen-rich blood flows in through the hepatic artery, while nutrients from the intestines come through the portal vein. Remember the sinusoids, This is where they get all that oxygen- and nutrient-rich blood.Blood leaves your liver via a central vein in each lobule, then through a hepatic vein, one of several short veins originating within the lobes of the liver as small branches. These unite in a network of hepatic veins that lead directly to the inferior vena cava. This major vein collects blood from parts of the body below your diaphragm, and passes that blood on for your heart to use.
- Correct Choice : D) 0
Solutions : There is no lead in pencils. Rather, the core is made up of a non-toxic mineral called graphite. Therefore % of lead in lead pencil is zero. There is absolutely no trace of lead in the lead pencil; as its marking element is made out of graphite, which is one of the natural forms of carbon.
The name lead pencil for a pencil is misnomer. As Romans happened to use a writing device called “stylus” in ancient times, which would write on wax surfaces using stylus, a pen-like writing device made of lead. One end of the stylus having a tapered finish was used for writing; while the other end was flattened and used as an eraser.
- Correct Choice : A) Facebook
Solutions : WhatsApp Messenger, or simply WhatsApp, is an American freeware, cross-platform centralized instant messaging (IM) and voice-over-IP (VoIP) service owned by Facebook, Inc. It allows users to send text messages and voice messages, make voice and video calls, and share images, documents, user locations, and other content. WhatsApp’s client application runs on mobile devices but is also accessible from desktop computers, as long as the user’s mobile device remains connected to the Internet while they use the desktop app. The service requires a cellular mobile telephone number to sign up. In January 2018, WhatsApp released a standalone business app targeted at small business owners, called WhatsApp Business, to allow companies to communicate with customers who use the standard WhatsApp client.
- Correct Choice : B) 1000 GB
Solutions : 1 TB equals 1,000 gigabytes (GB) or 1,000,000 megabytes (MB).

It also manages data flow between the computer’s operating system (OS) and attached devices, such as the hard disk, video adapter, keyboard, mouse and printer. The term BIOS was first coined in 1975 by American computer scientist Gary Kildall. It was incorporated into IBM’s first personal computer in 1981 and, in the years to come, gained popularity within other PCs, becoming an integral part of computers for some time. However, BIOS’ popularity has waned in favor of a newer technology: Unified Extensible Firmware Interface (UEFI). Intel announced a plan in 2017 to retire support for legacy BIOS systems by 2020, replacing them with UEFI.

Solutions : The greenhouse gases trap the heat from the sun so we don’t burn to a crisp because of the intensity. Atmospheric levels of carbon dioxide—the most dangerous and prevalent greenhouse gas—are at the highest levels ever recorded. Greenhouse gas levels are so high primarily because humans have released them into the air by burning fossil fuels. The gases absorb solar energy and keep heat close to Earth’s surface, rather than letting it escape into space. That trapping of heat is known as the greenhouse effect.
- Correct Choice : A) Nairobi
