Biology MCQs

Notes:
Mitosis is a fundamental process for life. During mitosis, a cell splits to form two identical daughter cells by duplicating all of its contents, including its chromosomes. Prophase, metaphase, anaphase & telophase are the stages of
Mitosis.

Notes:
Marsh Mallow is not a carnivorous plant. Whereas Pitcher plant, Venus Fly Trap and waterwheel plant are carnivorous plants. Carnivorous plants derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods.

Notes:
The human musculoskeletal system consists of human skeleton, bones attached to other bones with joints and skeletal muscle attached to the skeleton by tendons. It permits movement of the body, maintains posture and circulates blood throughout the body.

Notes:
The useful part of Zingiber officinale is rhizome. It is a flowering plant whose rhizome, ginger root or ginger, is widely used as a spice and also as a medicine. It is a herbaceous perennial plant.

Notes:
The chemical name of Vitamin B3 is Niacin which is a water soluble vitamin. It is an important nutrient. In fact, every part of your body needs it to function properly. As a supplement, niacin may help lower cholesterol, ease arthritis and boost brain function, among other benefits.

Notes:
Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.

Notes:
Eucalyptus is the fast growing tree. Most eucalyptus species have a root depth of 1.5-2.0 metre and its root system is more specifically adapted to using rain-fed soil moisture from the upper soil profile, rather than from the groundwater table at considerable depth. The plant is significant for wood availability, livelihood generation and carbon sequestration that address the challenges of global warming and climate change.

Notes:
If he inherits his mother’s other X chromosome, he will have normal blood clotting. So a carrier’s son has a 50% chance of having hemophilia. A baby girl will inherit an X chromosome with a dominant gene for normal blood clotting from her father. So the daughter will not have hemophilia.

Notes:
Alpha-keratin, or α-keratin, is a type of keratin found in vertebrates. This protein is the primary component in hair, horns, mammalian claws, nails and the epidermis layer of the skin. α-keratin is a fibrous structural protein, meaning it is made up of amino acids that form a repeating secondary structure.

Notes:
The scientific name of sea fan is Alcyonacea. Alcyonacea are an order of corals that do not produce calcium carbonate skeltons. They are found throughout the oceans of the world.
