What is thermometry?

Thermometry The branch of heat relating to the measurement of the temperature of a body is called thermometry. The thermometer is an instrument used to measure the temperature of a body. The essential requisites of a thermometer are given as under:  1) Construction, 2) Calibration, and 3) Sensitiveness. For the construction of a thermometer, the proper choice of a substance, whose physical property varies uniformly with rising in temperature, is essential. 1) Construction The physical property of a substance plays an important role in the construction of a thermometer. In a mercury thermometer, the principle of expansion of mercury with rising temperature is used. The platinum resistance thermometer is based on the principle of the change in resistance with a change in temperature. The gas thermometer is based on the principle of change in volume or pressure with a change in temperature. 2) Calibration  When a thermometer is constructed, it should be properly calibrated.

Kingdom Animalia

Image
Kingdom Animalia Characteristics: They are eukaryotic and multicellular animals. Their cells do not have nonliving cell walls, plastids, or vacuoles in them. As there are no plastids cells, they are heterotrophs, and so they depend on other organisms for their food. After ingestion, they digest their food. They have advanced and complex tissue systems. Sexual reproduction is their usual way of reproduction. Haploid gametes are usually produced in the reproductive organs of mature and diploid males and females. Embryonic layers are developed at the time of their embryonic development. Examples: The entire invertebrate and vertebrate animals except for protozoan. Thomas Cavlier-Smith from Oxford University divided the kingdom Protista of the living world into two groups, protozoa and chromista, and renamed the kingdom Monera as the Kingdom of Bacteria in 2004. In this way, he grouped the living world into six kingdoms.  You may like What do you mean by hierarchy? Why blue green

Branches of Biology

Branches of Biology When we look around us, we see two types of living things - plants and animals. Based on this, for a long time, biology was divided into two branches - Botany and Zoology. However, the field of biology has expanded so much that it is not enough to confine its study to these two branches only. There are many living beings that are neither plants nor animals, such as bacteria, fungi. The classification is not appropriate when analyzing common characteristics of animals, plants, bacteria, fungi, viruses, etc. So now also biology has been classified into many branches. Considering its aspect, there are also two other divisions of biology - Physical Biology and Applied Biology. Physical Biology In the field of Physical Biology, theoretical concepts are usually discussed. The following subjects are the general fields of its concern.

Concept of Biology

Concept of Biology In nature, we generally find two types of objects: non-living things and living organisms. The characteristics of non-living things are usually discussed in Physics and Chemistry. Biology is the branch of scientific knowledge concerning the life and characteristics of organisms.  But it is really difficult to find the very faint line of difference between living and non-living. In fact, physics and chemistry embody the principles of fundamentals of life, even non-living.  So, in order to understand living organisms, it is necessary to know about the physical sciences i.e. physics and chemistry. But it is wrong to think that it is not necessary to study biology if we have knowledge of physical sciences. Rather, life may be considered a complex combination of many non-living things in which some new characteristics occur. For example, the properties of water do not resemble that of hydrogen and oxygen, though it is made up of these two elements. So, although living

What do you understand by phosphorylation?

What do you understand by phosphorylation? When one or more phosphorus / phosphoric acid forms a bond with adenosine generated from a nitrogenous base and a pentose sugar- Adenosine Monophosphate, Diphosphate, Triphosphate are created. Usually, this phosphate addition reaction does not require external energy input and is widely known as phosphorylation. You May Like What is zoom?

What do you understand by anaerobic respiration?

What do you understand by anaerobic respiration? The respiration which occurs in absence of oxygen is called anaerobic respiration. In anaerobic respiration, respiratory substances being partially oxidized with the help of enzymes, produce different types of organic compounds (ethyl alcohol, lactic acid, etc), CO2 and a small amount of energy. Only in some microorganisms such as bacteria, yeast, etc. anaerobic respiration occurs. You May Like What is zoom? Affect vs Effect What do you understand by phosphorylation?

What is revolution?

Image
What is revolution? Revolution has been central to the formation of the modern world. The word itself refers to radical, transformative change and has many generic uses describing phenomena from the "industrial revolution" to the "sexual revolution". As a historical process, "revolution" refers to a movement, often violent, to overthrow an old regime and effect complete change in the fundamental institutions of society.  After the French Revolution of the 18th century which deposed the monarchy and attempted to refashion society from top to bottom, revolution became synonymous with the radical overcoming of the past. Modernity, many came to believe, could only be achieved through such violent and total transformation. The inspiration for many 20th century revolutions was the Russian Revolution of 1917 led by Vladimir Lenin and inspired by the ideas of Marxist Communism. Marx believed that revolution was necessary to move societies from one historical s

What is sinking fund?

What is sinking fund? A sinking fund is a fund containing money set aside or saved to pay off a debt or bond. A company that issues debt will need to pay that debt off in the future, and the sinking fund helps to soften the hardship of a large outlay of revenue. A sinking fund is established so the company can contribute to the fund in the years leading up to the bond's maturity. A sinking fund is a type of fund that is created and set up purposely for repaying debt. The owner of the account sets aside a certain amount of money regularly and uses it only for a specific purpose. Often, it is used by corporations for bonds and deposits money to buy back issued bonds or parts of bonds before the maturity date arrives. It is also one way of enticing investors because the fund helps convince them that the issuer will not default on their payments. Basically, the sinking fund is created to make paying off debt easier and to ensure that a default won't happen because there is a suffic
