How glucose break down by the complex |
| Answer» Breaking down glucose: This step happens in the cytoplasm. Glucose molecule is broken down into pyruvic acid. Glucose molecule is composed of 6 carbon atoms, while pyruvic acid is composed of 3 carbon atoms. Further breaking down of pyruvic acid takes place in mitochondria and the molecules formed depend on the type of respiration in a particular organism. Respiration is of two types, viz. aerobic respiration and anaerobic respiration. | |

Why does dry HCLgasnot change the colour of the dry litmus paper |
| Answer» We know that the colour of the litmus is changed by H+ ions of an acid. Dry HCl does not dissociate to give H+ ions. It is only in the aqueous that an acid dissociate to give ions. Since in this case, neither HCL is in aqueous form nor is the litmus paper wet, so the colour of litmus paper does not change. | |

How corrision is different from rusting |
| Answer» Rusting is chemical process and it is a type of corrosion. Which happens in the iron objects or objects containing iron metal. When iron or objects containing iron undergo corrosion, it is known as rusting. Rust is hydrated iron(III) oxide.The formula of rust is Fe2O3.nH2OOn the other hand corrosion is defined as " erosion reaction of metal with air and moisture when come to contact. Corrosion is essentially an electrochemical process. The eating up of metals by the action of air, moisture or a chemical on their surface is called corrosion.\xa0 | |

difference between centripetal force and a centrifugal force? |
| Answer» \tCentrifugal ForceCentripetal ForceIf an object moving in a circle and experiences an outward force, than this force is called as the centrifugal forceIf the object travels in a uniform speed in a circular path is called centripetal force.The object has the direction along the center of the circle from center approaching the objectThe object has the direction along the centre of the circle from the object approaching the center.Mud flying of a tire is one example of the centrifugal force.Satellite orbiting a planet is an example of the centripetal force.Centrifugal force is an outward force.Centripetal force is an inward force.Centrifugal has been derived from the latin words centrum and fugere, which means to flee.Centripetal has been derived from the latin words centrum, which means centre and petere, which means to seek.\t | |

T.S of leaf |
| Answer» A transverse section of typical leaf shows that it is covered by epidermis on both surfaces. Epidermis is interrepted by large number of openings called stomata. The central opening is called stoma. Each stoma is surrounded two kidney shaped cells called Guard cells. Stoma regulate the exchage of gases and loss of water vapour from the leaves. Tissues enclosed between the two epidermal layers is called the mesophyll. Mesophyll consists of elongated cells arranged in rows called the palisade parenchyma. It also has irregularly arranged cells with large intercellular spaces known as spongy parenchyma. The mesophyll cell contain abundant chloroplasts. More palisade tissue occurs in leaves exposed to bright light that those exposed to shade. Vascular bundles in the leaf are located in the midrib and the veins. In each vascular bundle of the leaf, phloem is located towards the lower side and xylem towards upper side. | |
