Biology MCQs

Notes:
Herpetology is the branch of zoology which deals with the study of amphibians such as frogs, toads, salamanders, newts and the gymnophiona; and reptiles such as snakes, lizards, amphisbaenids, turtles, terrapins, tortoises, crocodilians and the tuataras.

Notes:
Hydrophobia which is also known as Rabies is a viral disease that causes inflammation of the brain in humans and other mammals. Some of the early symptoms can include fever and tingling at the site of exposure.

Notes:
Theory of natural selection was proposed by Darwin.The theory is an explanation for adaptation and speciation. He defined natural selection as the “principle by which each slight variation [of a trait], if useful, is preserved”.

Notes:
Lipids are categorised within a group of naturally occurring molecules, including fats, waxes, sterols, fat-soluble vitamins and others. They are hydrophobic or non-polar, which explains why they’re not soluble in water, a polar substance, but are soluble in organic, non-polar solvents.

Notes:
Enteric fermentation is a digestive process that takes place in the digestive systems of ruminant animals by which carbohydrates are broken down by microorganisms into simple molecules for absorption into the bloodstream of an animal.

Notes:
Mumps is caused by Virus. Mumps is a viral infection that affects the salivary glands that’s easily preventable by a vaccine. Initial signs and symptoms include fever, muscle pain, headache, poor appetite, and feeling generally unwell.

Notes:
Cobalt is a component of Vitamin B12. Vitamin B12 is also known as also known as cobalamin, is an important water-soluble vitamin which is used in the production of red blood cells and DNA.

Notes:
In humans, fertilization normally occurs in the fallopian tube. The ovary is the female gonad that contains the eggs. The uterus is the organ that houses the developing embryo. The placenta is the structure that nourishes the embryo.

Notes:
Epiphytic roots are the roots of some orchid plants, which hang in the air and absorb moisture and nutrients from the air, rain water. Examples of epiphytic roots are mosses, liverworts, lichens, and algae of temperate zone and ferns, cacti, orchids, and bromeliads in the tropics.

Notes:
Golden Rice is a genetically engineered (GE) rice variety that has been developed by the biotech industry to produce pro-vitamin A. Vitamin A deficiency can be caused by infections that reduce appetite or the body’s ability to absorb vitamin A or may cause night blindness. Golden Rice has the potential to complement existing efforts that seek to reduce blindness and other VAD induced diseases.
