Mutation usually occurs when there is an error in the pairing of gametes during the crossing over stage of meiosis. There are many types of chromosomal mutation and these are: translocation, duplication, deletion, and inversion. Changes in the number of chromosomes may lead to unique changes in physical and behavioral traits of organisms.
Answer:
Anaerobes are not able to have growth in the presence of much of oxygen environment as they do not have catalse .Catalse is the enzyme for clearance of oxygen.There are also anaerobes protects their own self from oxygen by production of an enzyme known as super oxide dismutase. Therefore, it is not easy task for creation an oxygen-absent environment for anaerobes in the vitro so they cannot be grown in vitro.
The answer is TRUE. Water that contains dissolved minerals is called hard water.
Answer:
The difference is the organization of the fibers located in the extracellular matrix.
Explanation:
The connective tissue gives support and structure to other tissues and organs. Diverse cells, fibers and ground substance (matrix) are components of the connective tissue. The connective tissue is classified in: loose or dense. As their names imply, loose connective tissue has fewer cells and fibers per area whereas in the dense connective tissue the cells and fibers are tightly packed. The dense connective tissue is further divided into regular and irregular. The main difference is the arrangement of the fibers in these tissues. In the regular dense connective tissue, all the fibers are oriented in one direction. In contrast in the irregular dense connective tissue the fibers have multiple orientations
