The correct answer is Calamine.

Key Points

• Calamine is used to reduce the irritating effect of ambient because it reacts with sodium hydrogen carbonate released due to the ba few with formic acid present in calamine.
• Ants release a chemical called formic acid onto your skin when they bite.
• The release of this acid. along with the pinch form from the mandibles, cues symptoms of an ant bite.

Additional Information

• Benzyl Alcohol is a base.

The correct answer is HCl.

• **A solution reacts with chalk powder to give a gas that turns lime-water milky. The solution contains HCl.**​

Important Points

• Chalk will dissolve in a strong acid such as hydrochloric even when diluted.
• The chemical formula of chalk is CaCO₃.
• The chemical formula of hydrochloric acid is HCl.
• Chalk powder when reacted with hydrochloric acid releases carbon dioxide which turns lime water milky.

 Additional Information

Reptiles is NOT correct.

Key Points

• Among the options, only reptiles do NOT include Invertebrates.
• An invertebrate is a cold-blooded animal without a backbone.
• They can live both on land and water.
• More than 90% of all living animal species are invertebrates.
• Important examples of invertebrates are:
• Arthropods (insects, arachnids, crustaceans, and myriapods).
• Molluscs (chitons, snail, bivalves, squids, and octopuses).
• Annelid (earthworms and leeches).
• Cnidarians (hydras, jellyfishes, sea anemones, and corals).
• Crustaceans (such as crabs and lobsters), Molluscs (such as squids and clams), and coral are examples of marine invertebrates.

Important Points

• Reptiles are vertebrates.
• Snakes, turtles, lizards, and crocodilians are examples of Reptiles.
• Asian saltwater crocodile is the largest reptile in the world.
• Dwarf gecko is the smallest lizard in the world

The correct answer is Lichen.

Key Points

• A mutual relationship in which organisms live together and share their shelter and nutrients is called a symbiotic relationship.
• Lichens are made up of two or more closely interacting organisms, a fungus, and one or more partners called photobionts.
• Lichens are an association of alga and fungus living together for their mutual benefits
• The fungus provides shelter and maintains the humidity for alga inside the lichen body, necessary for the alga for the process of photosynthesis.
• The alga in return provides the food material, prepared during photosynthesis to the fungus.
• Examples of symbiotic relationships are:
• Relation between bee and a flower.
• Rhizobium bacteria and leguminous plants.
• Relationship between an anemone (Heteractis Magnifica) and a clownfish (Amphiron ocellaris).

The correct answer is Coulomb.

Key Points

• The SI unit of electric charge is Coulomb.

Additional Information 

• There are 7 base Units, which are -

The correct answer is Zn.

Key Points

• Zinc is a chemical element with the symbol Zn and atomic number 30.
• Atomic Number is defined as the number of protons in the nucleus of an element.
• It is used to determine the characteristics of an element and it is also referred to for placing an element in the Periodic Table.
• The Atomic Number of Zinc (Zn) is 30 whereas the Mass Number is 65 i.e. it has 35 neutrons.
• It is the first element in group 12 (IIB) of the periodic table.
• Zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn²⁺ and Mg²⁺ ions are of similar size.

Additional Information

The correct answer is Metaphase.

Key Points

• Mitosis is a kind of cell division in which one cell (the mother) divides to generate two genetically identical new cells (the daughters).
• Mitosis is the stage of the cell cycle's division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
• Mitotic divisions are a mode of reproduction for single-celled eukaryotes like yeast, contributing new individuals to the population.
• Phases of mitosis:
• Interphase:
• In preparation for cell division, the DNA in the cell is replicated, resulting in two identical full sets of chromosomes.
• Two centrosomes, each comprising a pair of centrioles, are located outside of the nucleus and are essential for cell division.
• Microtubules extend from these centrosomes during interphase.
• Prophase:
• Under a microscope, the chromosomes condense into X-shaped structures that are plainly visible.
• Each chromosome is made up of two sister chromatids, each of which contains the same genetic material.
• The chromosomes are paired up so that both copies of chromosome 1 are together, and so forth.
• The membrane around the nucleus in the cell dissolves at the conclusion of the prophase, freeing the chromosomes.
• The mitotic spindle, which is made up of microtubules and other proteins, spans the cell and connects the centrioles as they travel to opposite poles.
• Metaphase:
• The chromosomes are perfectly lined up end-to-end along the cell's equator.
• The mitotic spindle threads extend from the centrioles, which are now at opposing poles of the cell.
• The sister chromatids are connected by the mitotic spindle threads.
• Anaphase: 
• The mitotic spindle then pulls the sister chromatids apart, pulling one chromatid to one pole and the other chromatid to the opposite pole.
• Telophase: 
• A complete pair of chromosomes assemble at each cell pole.
• To build two new nuclei, a membrane forms surrounding each set of chromosomes.
• The single-cell then pinches in the middle, separating into two daughter cells, each with a nucleus and a full set of chromosomes. Cytokinesis is the name for this process.

The correct answer is Ne.

Key Points

• The noble gases are uncolored, scentless, bland, nonflammable gases that were once classified.
• They were once classify group 0 in the periodic table because it was considered they had a valence of zero, meaning their atoms cannot integrate with those of other elements to form compounds.
• The noble gases have full valence electron shells. Valence electrons are the extreme electrons of an atom and are usually the only electrons that partake in chemical bonding.

Additional Information

• Nitrogen is the chemical element with the letter N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table
• Fluorine is a chemical element with the letter F and atomic number 9. It is the lightest halogen and exists at accepted conditions as a highly harmful, pale yellow diatomic gas.
• C​alcium (Ca), chemical element, one of the acidic-earth metals of Group 2 (IIa) of the periodic table. It is the most ample burnished element in the human body and the fifth most ample element in Earth’s crust.

The correct answer is Large intestine.

• The Large intestine is not a part of the circulatory system.

Key Points

• Circulatory System:
• The discovery of blood circulation was done by William Harvey.
• It is also called the cardiovascular system.
• It delivers oxygen and nutrients to cells and removes wastes.
• The heart and its parts, capillaries, veins, and blood are part of the circulatory system.
• The heart pumps oxygenated and deoxygenated blood.
