structure during embryologic development. It is associated with the formation of the head and neck. It consists of the branchial arches‚ the pharyngeal pouches‚ the branchial clefts or grooves and the branchial membranes (not pictured). A four-week-old embryo features four visible branchial arches separated by branchial grooves. They are numbered craniocaudally. A fifth and a 6th are also present but are very small. A primitive mouth appears as a small depression referred to as stomatodeum (stomodeum)

Couplings are mechanical elements that ‘couples’ two drive elements which enables motion to be transferred from one element to another. The drive elements are normally shafts. We tend to see lot of applications of the couplings mainly in the automobiles‚ for example the drive shaft which connects the engine and the rear axle in a bus or any automobile is connected by means of a universal joint. In order to transmit torque between two shafts that either tend to lie in the same line or slightly misaligned

instructions carried on DNA are used to make proteins from amino acids in the cytoplasm. RNA must first make a copy of DNA in the nucleus before the proteins can be built by ribosomes in the cytoplasm. 1B.Typical RNA Molecule RNA has larger grooves‚ which makes it vulnerable to attacks by enzymes. B form defines the helix geometry of DNA. The body destroys enzymes that cling to DNA. It can be though damaged by exposure to ultra violet rays. General Comparison Though both DNA and RNA consist

Heating effect of electric current are below (i) Electric iron: In an iron the upper part is grooved. In this groove a coil is placed. Mica as an insulator is placed between the metal part and the coil‚ so that there is no electrical connection between them. Mica is a bad conductor of electricity but it is a good conductor of heat.
