Write two points of difference between:1) Parallel venation and Reticulate venation.2) Physical change and Chemical change. |
|
Answer» Explanation: Parallel Venation. Reticulate Venation. Meaning. When veins (or the nerves) are arranged parallel to one another all over the leaf blade or LAMINA is called as parallel venation. When veins (or the nerves) shows network or web-like arrangement all over the leaf blade or lamina, it is called as reticulate venationReticulate venation is one of the types of classifications of vein patterns that are typically found in leaves. Here, veins are interconnected to form a web-like network. It is one of the most common vein formations in leaves and can be found in the leaves of rose bushes, oak trees and maple trees. These veins TRANSPORT water and food from the leaves throughout different plant parts. There are two other classifications of vein patterns namely – dichotomous and parallel. Dichotomous venation occurs very rarely compared to other classifications and has veins that branch off from one another whereas parallel venation is characterized by veins running parallel to one another. For instance, venation observed in grass and Lillies. Difference between Reticulate and Parallel Venation Reticulate venation Parallel venation Definition When the veins are arranged in either web-like or network-like all over the lamina, it is known as reticulate venation When the veins are arranged parallel to one another all over the lamina, it is known as parallel venation Orientation Network or web-like structure Parallel to one another Found in Dicot plants Monocot plants Examples Mango and hibiscus Banana and bamboo Related Questions & Answers The Least Count Of A Stop Watch Is Generally List The Different Types Of Movements EXHIBITED By The Human Body Heterotrophic Nutrition Is Not Shown By In The Following X T GRAPH Which Path Represents The Displacement Explain Ideal Gas Matter In Any Form Is Made Up Of Fill In The Blank How Are Alveoli Designed To Maximize The Exchange Of Gases What Are The Factors Affecting The Product Of Electrolysis What Are Checkpoints In Cell Cycle What Is Primary Succession Relevant Subjects Similar Questions Amoeba Digests Its Food In The What Is The Life Span Of The Banyan Tree And Peepal Tree Name The Acid Present In Apple Tomato Grapes Rancid Butter Bees And Oranges What Is A Substrate How Does Mining Affect Climate Change What Is An Example Of An Aquatic Plant What Are The Different Branches Of Agriculture Why Is Food Digestion A Chemical Change What Is Pulvinus In Leaves In Which Plants Is It Found What Are Their Functions What Is The Name Of The Smallest BONE In The Skeletal System Where In The Body Is This Bone Found Leave a Comment Your email address will not be published.

|
Answer» Answer: ANSWER Epithelial tissue lines the surface of a body and forms a PROTECTIVE covering. Epithelium cells are packed tightly together with a little intercellular matrix. Epithelial tissue in the body is of two types - A. Simple epithelium: It consists of a single layer of cells where cells are in direct contact with the basement MEMBRANE. It is further sub-divided into the following types: (i) Simple squamous epithelium: It consists of a single layer of flat cells with irregular boundaries. It is found in the walls of the blood vessels and in the lining of alveoli. (ii) Simple cuboidal epithelium: It consists of a single layer of cube-like cells. It is present in regions where secretion and absorption of substances take place such as the proximal convoluted tubule region of the nephron. (iii) Simple columnar epithelium: It consists of a single layer of tall, SLENDER cells with their nuclei present at the base of the cells. They may bear microvilli on the free surfaces. Columnar epithelium forms the lining of the stomach and intestines and is involved in the function of secretion and absorption. (iv) Ciliated epithelium: It consists of columnar or cuboidal cells with cilia on their free surfaces. They are present in bronchioles and oviducts from where they direct mucus and eggs in specific directions. (v) Glandular epithelium: It consists of columnar or cuboidal cells involved in the secretion of substances. Glands are of two types, unicellular glands (goblet cells of the alimentary canal) and multicellular glands (salivary glands). They can be classified as exocrine (ductless glands) and endocrine glands (duct glands) by the method through which they release their secretions. B. Compound epithelium: It consists of many layers of cells. It is involved mainly in the function of providing protection and has a limited role in secretion and absorption. Dry surface of the skin or moist inner lining of the buccal cavity, PHARYNX, pancreatic DUCTS and the inner lining of ducts of salivary glands are some of the examples of the compound epithelium. |

Answer» The best way to protect yourself from contracting coronaviruses is by using the same daily habits that help prevent the spread of many viruses, including the common cold and the flu. To help prevent the spread of disease always: Avoid close contact with people who are sick. Wash your hands with soap and water frequently. Wash with soap and warm water for 20 seconds. If soap and water aren't available, use an alcohol-based hand rub. Avoid TOUCHING your eyes, nose, and MOUTH with UNWASHED hands. Stay HOME when you’re sick (and keep sick children home from school). Cover your cough or sneeze with a tissue, then throw the tissue in the trash and wash your hands. If you don't have a tissue, cough or sneeze into your upper sleeve or elbow, not your hands.

36. Write a note on chloral alkal process with diagram |
|
Answer» Explanation: Usually the process is conducted on a BRINE (an AQUEOUS solution of NaCl), in which case NaOH, hydrogen, and chlorine result. When using calcium chloride or potassium chloride, the products contain calcium or potassium instead of sodium. Related processes are known that use molten NaCl to give chlorine and sodium metal or condensed hydrogen chloride to give hydrogen and chlorine. The process has a high energy consumption, for example around 2500 kWh of electricity per tonne of sodium HYDROXIDE produced. Because the process yields equivalent amounts of chlorine and sodium hydroxide (two moles of sodium hydroxide per mole of chlorine), it is necessary to find a use for these products in the same proportion. For every mole of chlorine produced, one mole of hydrogen is produced. MUCH of this hydrogen is used to produce hydrochloric acid, ammonia, hydrogen peroxide, or is burned for power and/or steam production.[3] |

State the principle of conservation of linear momentum. Illustrate by an example |
|
Answer» Answer: Conservation of LINEAR momentum, general law of PHYSICS according to which the quantity called momentum that characterizes MOTION never changes in an isolated collection of objects; that is, the total momentum of a system remains constant. Conservation Of Linear Momentum Example Two bodies of mass M and m are MOVING in opposite directions with the velocities v. If they collide and move together after the collision, we have to find the velocity of the system. SINCE there is no external force acting on the system of two bodies, momentum will be conserved. |
