Biology MCQs

Notes:
Cobalamine indicates Vitamin B12. It is a water-soluble vitamin and plays an essential role in the production of your red blood cells and DNA, as well as the proper functioning of our nervous system.

Notes:
Most of the essential micronutrients are almost exclusively stored in the husk, aleurone and embryo of rice, which are removed during the polishing process. Polishing of rice is required as the oil-rich aleurone layer turns the seed rancid upon storage and therefore making rice unsuitable for consumption. Consequently, the rice endosperm that comprises the edible part of rice for humans lacks or contains only small amount of key micronutrients (e.g., iron, zinc, protein, provitamin A, and other vitamins) that are essential for a healthy diet. Considering the facts above and severity of widespread micronutrient malnutrition, iron biofortification in rice endosperm is a promising strategy to overcome iron deficiency effectively.

Notes:
The interventricular foramen is also known as foramen of Monro. It is a part of the ventricular system and the connection between the third ventricle and the lateral ventricles.

Notes:
Potato and Brinjal have several common features and are thus included in the same genus Solanum. The scientific name of Potato is Solanum tuberosum and Brinjal is Solanum melongena.

Notes:
Scurvy is the name for a vitamin C deficiency. It can lead to anemia, debility, exhaustion, spontaneous bleeding, pain in the limbs, and especially the legs, swelling in some parts of the body, and sometimes ulceration of the gums and loss of teeth.

Notes:
Entomology is the scientific study of insects, a branch of zoology. In the past the term “insect” was more vague, and historically the definition of entomology included the study of terrestrial animals in other arthropod groups or other phyla, such as arachnids, myriapods, earthworms, land snails, and slugs.

Notes:
Metaxylem is the part of the primary xylem that differentiates after the protoxylem and that is distinguished typically by broader tracheids and vessels with pitted or reticulate walls.

Notes:
Growing kids need protein to help them build and repair cells, enzymes, and hormones, and, as a last resort, to provide energy. Protein foods also help form new blood cells and body tissues, and they help the nervous system function properly.

Notes:
Among the above all, the sugarcane has the highest photosynthetic activity. Photosynthesis is a chemical process that occurs in many forms of bacteria and virtually all plants, including aquatic plants and algae. The rate of photosynthesis in a plant is dependent on the environmental changes, as well as to intrinsic features of plant. The photosynthetic rate in sugarcane is directly related with the variation of solar radiation during the day.

Notes:
Haemophilia is a mostly inherited genetic disorder that impairs the body’s ability to make blood clots, a process needed to stop bleeding. This results in people bleeding longer after an injury, easy bruising, and an increased risk of bleeding inside joints or the brain.
