- Question
Where is excess glucose stored?
Options- A. Blood
- B. Liver
- C. Heart
- D. Kidneys
- Correct Answer
- Liver
ExplanationGlucose is essential for energy in all the living organisms. When we have more glucose than needs in our bloodstream, then the excess glucose is stored as large compounds as Glycogen. This glycogen fills the cells of the liver and available for any quick shots of energy.
Hence, Liver is called as warehouse for the excess glucose.

Correct Answer: acromion
Correct Answer: Sporophytes are diploid, whereas gametophytes are haploid.
Explanation:
Sexual reproduction results in gametes that combine two cells from different individuals. Meiosis also produces gametes. Haploids contain one set of chromosomes in each of their cells. Diploids cells contain two chromosome sets. For plants, haploid and diploid cells divide via mitosis. The plants? haploid phase is called the gametophyte, and the diploid phase is called the sporophyte.
Sporophytes are diploid plants that use meiosis to produce spores. These spores are haploid cells that grow into haploid gametophytes. Megaspores grow into female gametophytes, and microspores grow into male gametophytes.
Gametophytes are haploid plants that use mitosis to make haploid gametes. These gametes are female in the form of an ovum (egg) or male in the form of sperm.
Correct Answer: Individuals moving into population
Explanation:
Gene flow means migration of genes from one to another. This gene flow is caused by individuals moving into population.
Correct Answer: All of the above
Correct Answer: Proteins
Explanation:
Enzymes are protein macromolecules. Enzymes are almost always made of proteins only. Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids. There are 20 different common amino acids that make up proteins like enzymes. Of these, nine amino acids are essential, which means you must get them from your diet.
Enzymes catalyze chemical reactions in biological systems. This means that they speed up the rate of the reaction.
Correct Answer: urinary output
Correct Answer: Sperms
Explanation:
In the above options, sperms are the haploid cells. In humans, haploid cells are those have only half the number of usual number of chromosomes. Sperm, gamates and egg cells are the haploid cells examples.
Correct Answer: appositional growth
Correct Answer: Both A & B
Explanation:
The nervous system of the human brain consists of the central nervous system which has brain and the spinal cord and the peripheral nervous system which has perpheral, cranary, spinal nerves.
Correct Answer: Pathogenic
Explanation:
Pathogenic bacteria cause the greatest harm in the food industry.
