Biology MCQs

Notes:
Hemoglobin is the iron-containing oxygen-transport metalloprotein in the red blood cells of almost all vertebrates as well as the tissues of some invertebrates. Haemoglobin in the blood carries oxygen from the lungs or gills to the rest of the body.

Notes:
In Mitochondria, pyruvic acid is broken down into carbon dioxide, water and energy.

Notes:
Adipose tissue is an anatomical term for loose connective tissue composed of adipocytes. Its main role is to store energy in the form of fat, although it also cushions and insulates the body.

Notes:
Tissue culture is the growth of tissues or cells in an artificial medium separate from the organism. Tissue culture commonly refers to the culture of animal cells and tissues, with the more specific term plant tissue culture being used for plants.

Notes:
Ringworm isn’t a worm. It’s a skin infection that’s caused by moldlike fungi that live on the dead tissues of your skin, hair, and nails. It can occur at any place and on your scalp. When one gets it between the toes, it’s what people call athlete’s foot.

Notes:
The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle. The right coronary artery supplies blood to the right side of the heart.

Notes:
Ecosystems are capable of maintaining their own state of equilibrium. They can regulate their own species structure and functional processes. This capacity of ecosystem of self regulation is referred to as homeostasis.

Notes:
The North Atlantic right whale is a baleen whale. At present, they are among the most endangered whales in the world. They feed on plankton and are usually found in coastal waters.

Notes:
Louis Pasteur was a French biologist, microbiologist, and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and prevention of diseases, and his discoveries have saved many lives ever since. He reduced mortality from puerperal fever and created the first vaccines for rabies and anthrax. His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. He is best known to the general public for his invention of the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization. He is regarded as one of the three main founders of bacteriology, together with Ferdinand Cohn and Robert Koch, and is popularly known as the “father of microbiology”.

Notes:
The branch of science that deals with the study of the mental faculties of the brain including emotions is known as Phrenology.
