The HAVING clause was added to database because the WHERE keyword could not be used with aggregate functions. Solution Yes what you said is true. The syntax of SQL statement with HAVING clause will be like:- SELECT column_name, aggregate_function(column_name) FROM table_name WHERE column_name operator value GROUP BY column_name HAVING aggregate_function(column_name) operator value;.

8. You may have heard that drinking soda or acid is bad for your teeth. The enamel on your teeth consists of the mineral hydroxyapatite, Ca (PO(OH) a. Is hydroxyapatite an acid or base? Hint: look at the ions in the chemical formula. b. Based on your answer to Sa, is acid good or bad for your teeth? Give reasons c. How does flouride prevent cavities? Hint: Fluoride reacts with hydroxyapatite in a double : 40 with acid. Solution Ans A. It is acidic since n sloution produces phosphate ion . Ans B. No it is not good, since it increase the production of Lactic acid and bacteria lives ore. Ans C. It is called remineralization. When fluoride is present during remineralization, the minerals fabriacted into the tooth enamel help strengthen teeth and prevent dissolution during the next demineralization phase. In this way, fluoride helps stop the decay process and prevent tooth decay.

Why is it that ozone is not desirable at the surface of earth, but is desirable in the stratosphere? Solution Ozone occurs naturally in the stratosphere and is produced and destroyed at a constant rate. But this \"good\" ozone is gradually being destroyed by manmade chemicals called chlorofluorocarbons (CFCs), halons, and other ozone depleting substances (used in coolants, foaming agents, fire extinguishers, and solvents). These ozone depleting substances degrade slowly and can remain intact for many years as they move through the troposphere until they reach the stratosphere. There they are broken down by the intensity of the sun\'s ultraviolet rays and release chlorine and bromine molecules, which destroy \"good\" ozone. One chlorine or bromine molecule can destroy 100,000 ozone molecules, causing ozone to disappear much faster than nature can replace it. It can take years for ozone depleting chemicals to reach the stratosphere, and even though we have reduced or eliminated the use of many CFCs, their impact from years past is just starting to affect the ozone layer. Substances released into the air today will contribute to ozone destruction well into the future. Satellite observations indicate a world-wide thinning of the protective ozone layer. The most noticeable losses occur over the North and South Poles because ozone depletion accelerates in extremely cold weather conditions..

Snakes develop about 10x the number of somites as a chicken or mouse. Use the clock- wavefront model to explain the molecular basis of this evolutionary difference. First describe the model, citing experimental support as needed, and then explain how it is modified to produce additional somites in snakes. Solution The clock and wavefront model is a model used to describe the process of somitogenesis in vertebrates. Somitogenesis is the process by which somites, blocks of mesoderm that give rise to a variety of connective tissues, are formed. The model describes the splitting off of somites from the paraxial mesoderm as the result of oscillating expression of particular proteins and their gradients. Once the cells of the pre-somitic mesoderm are in place following by cell migration during gastrulation, oscillatory expression of many genes begins in these cells as if regulated by a developmental \"clock.\" This has led many to conclude that somitogenesis is coordinated by a \"clock and wave\" mechanism. More technically, this means that somitogenesis occurs due to the largely cell-autonomous oscillations of a network of genes and gene products which causes cells to oscillate between a permissive and a non-permissive state in a consistently timed-fashion, like a clock. These genes include members of the FGF family, Wnt and Notch pathway, as well as targets of these pathways. The wavefront progresses slowly in an anterior-to-posterior direction. As the wavefront of signaling comes in contact with cells in the permissive state, they undergo an epithelial-mesenchymal transition and pinch off from the more posterior pre-somitic mesoderm, forming a somite boundary and resetting the process for the next somite. In particular, the cyclic activation of the Notch pathway appears to be of great importance in the wavefront-clock model. It has been suggested that the activation of Notch cyclically activates a cascade of genes necessary for the somites to separate from the main paraxial body. This is controlled by different means in different species, such as through a simple negative feedback loop in zebrafish or in a complicated process in which FGF and Wnt clocks affect the Notch clock, as in chicks and mice.Generally speaking, however, the segmentation clock model is highly evolutionarily conserved. Intrinsic expression of “clock genes” must oscillate with a periodicity equal to the time necessary for one somite to form, for example 30 minutes in zebrafish, 90 minutes in chicks, and 100 minutes in snakes. somites form from the paraxial (somitic) mesoderm, a particular region of mesoderm in the neurulating embryo. This tissue undergoes convergent extension as the primitive streak regresses, or as the embryo gastrulates. The notochord extends from the base of the head to the tail; with it extend thick bands of paraxial mesoderm.As the primitive streak continues to regress, somites form from the paraxial mesoderm by \"budding off\" rostrally as somitomeres,.

Provide a one-sentence definition for horizontal gene transfer. What is the significance of horizontal gene transfer for prokaryotic genetic diversity and classification? How is horizontal gene transfer accomplished? Solution Answer: (A) Horizontal gene tansfer: It is a process through which genetic material are transferred between bacteria that are not parents and offspring. (b) Through horizontal gene transfer, a substantial amount of genetic material can be inserted or deleted from genomes of prokaryotic organisms. Insertion of new trait from one distant related organism to other organism through horizontal gene transfer can lead to new pathogenic and ecological character thus causing microbial diversification. (c) Horizontal gene transfer is accomplished by three main mechanism: Transformation:Genetic material of an individual cell is altered by the direct incorporation of foreign (exogenous) DNA into its genome. Transduction: This process involves transfer of DNA from one bacterium into another through bacteriophages. Conjugation: Conjugation required cell to cell contact or any sexual pilus for transfer of DNA..

10. a) Investigate and briefly report on the cleansing action of soap from the perspective of micelles. hi Comnare and contrast solutions colloida Solution The soap molecule has a hydrophilic polar head and a hydrophobic non-polar hydrocarbon tail. The hydrophilic polar head binds with water and the hydrophobic non-polar hydrocarbon tail binds with grease, oil and other non-polar dirt. When oil, grease or dirt is mixed with the soap water, the soap molecules arrange themselves to form tiny clusters called micelles. The hydrophilic part of the soap molecules moves towards the water and the hydrophobic part point outwards and form outer surface of the micelle. The hydrophobic parts moves towards oil, grease or non-polar dirt and form a trap, where, the hydrophobic dirt is in the center and can\'t come outside, preventing the contact with water. Thus the micelle is soluble in water with the hydrophobic dirt is in the center and when rinsing the soapy water, the hydrophobic dirt also goes along with it. Use comment box if further clarifications required.
