Answer:
The correct answer is - 20000, 25,000 genes.
Explanation:
Genes are made by the functional and physical unit of the heredity called DNA. Genes are the precursors or encoded instructions to make a specific protein. Genes can be small or large depending on the DNA bases present in it which can be hundreds to millions in numbers.
According to the Human Genome Project, which found out the total genes present in a human genome between 20000 to 250000 genes approximately.
Thus, the correct answer is - 20000, 25,000 genes.
Answer;
-Matrix
Explanation;
Matrix is used to maintain artificial wall around the tooth preparation.
Cavity preparation is the mechanical alteration of a tooth to receive a restorative material which will return the tooth and area to proper form, function and esthetics.
-Objectives of cavity Preparation: remove all defects and give the necessary protection to the pulp, locate the margins of the restoration as conservatively, form the cavity so that under the forces of mastication the tooth or the restoration will not be displaced and also Allow for the esthetic and functional placement of a restorative material.
What causes hemolytic disease of the newborn (HDN)? HDN most frequently occurs when an Rh negative mother has a baby with an Rh positive father. When the baby's Rh factor is positive, like the father's, problems can develop if the baby's red blood cells cross to the Rh negative mother.
Answer: Hydroelectric power will be the best energy source.
Explanation:
<u>Solar energy-</u> It refers to the energy that is directly derived from the sun, and are later used to convert into some kind of electrical or thermal energy. For example, solar panels.
<u>Biomass energy-</u> It is a type of energy that are directly obtained from the plants as well as organisms. This can be regenerated again and again. For example, bio-gas and food crops.
<u>Hydroelectric power-</u> It is a type of energy that is collected, from the rapid motion of water. A dam is needed to construct across a narrow river, which will store water as a reservoir. And this water, when allowed to flow then it initiates the movement of the turbines and due to this continuous motion of the turbines, electricity is generated.
Thus, the most efficient energy source for the given area is the hydroelectric energy, that fulfills the condition for setting up dams in the two rivers, which will generate a huge amount of electricity.
Lysozyme is found throughout our bodies in mucous membranes and saliva to protect us from infection. Some bacteria are able to evade this defense by altering their peptidoglycan.
<h3>What are
Lysozymes?</h3>
Animals generate the antimicrobial enzyme lysozyme, also known as muramidase or N-acetylmuramide glycanhydrolase, which is a component of the innate immune system. The glycoside hydrolase lysozyme is responsible for breaking down the 1,4-beta-linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in peptidoglycan, the main building block of gram-positive bacteria. The integrity of the bacterial cell walls is subsequently compromised by this hydrolysis, leading to lysis of the cells.
