Correct Answer: Mitochondria
Explanation:
Mitochondria which is present in both plant and animal cells supplies energy to the cells and hence called as the powerhouse of the cell.
Correct Answer: Cornea
Explanation:
Corneas are only tissues that don?t have blood vessels. Tissues are the level cellular organization in the human body which lies between cells and a complete organ. Tissues of similar cells group together to form an organ.
There are four types of tissues. They are :
Epithelial,
Connective,
Muscular, and
Nervous tissue.
Correct Answer: Vitamins are indispensable for the maintenance of optimal health
Explanation:
Vitamins are indispensable for the maintenance of optimal health is the only statement that is true about vitamins.
Correct Answer: how certain nutrients affect an individual's gene expression
Explanation:
Nutritional genomics is a science studying the effects of food and food constituents on gene expression and the relationship between human genome, nutrition and health. It is also known as nutrigenomics. It also studies how genetic variations affect the nutritional environment.
Correct Answer: all enzymes have the same shape as their substrates
Explanation:
All enzymes have the same shape as their substrates is the FALSE statement regarding enzymes.
Correct Answer: Hypovitaminosis D
Explanation:
Vitamin D also known as Sunshine vitamin is produced in the body when our skin is exposed to sunlight. Its deficiency leads to a disease in which bone tissue doesn't properly mineralize leading to soft bones. The vitamin D deficiency disease in adults is known as Hypovitaminosis D.
Correct Answer: double internal fertilization
Explanation:
The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants. These are also seed producing plants like gymnosperms. In Angiosperms seeds are in flowers.
Correct Answer: Active and passive humoral immunity are both mechanisms of adaptive immunity that useantibodies
Correct Answer: Abdomen
Explanation:
Visceral pain is a poorly localized, dull, or diffuse pain. It usually arises from the abdominal organs.
Correct Answer: Semicircular Canals
Explanation:
Dynamic equilibrium receptors are found in the Semicircular Canals. It monitors angular or rotational movements of the head when the body ismoving, such as a figure skater?s spinning, but maintaining balance.
