Distance/Time = 120 Km/2 hours =120/2 Km per hour or for short 60 Km per hour
The indications for using restraints are that the person is uncooperative and hysterical so that means that he/she may try to lash out at someone and hurt someone or themselves so restraint is a pre-cautionary measure to ensure no one is hurt.
Ans. (A). photosynthesis.
The green disks in Elodea plant cell under a microscope represent specialized plant cell organelles, known as chloroplasts. Chloroplasts are double-membrane bound cell organelles that contain green pigments or chlorophyll molecules.
These pigments trap the energy from solar light, which is used by the plants for the process of photosynthesis to make their food.
Thus, the correct answer is option (A).
Answer:
The correct option is <em>B) ultraviolet region, especially below a wavelength of 320 nm.</em>
Explanation:
Ultraviolet light carries an enormous amount of energy in it. It is invisible to the human eye. When UV light with enormous energy and wavelength lesser than 320nm, hits the DNA, it causes changes in the structure of the DNA. Mostly, it affects the thymine nitrogenous base regions and forms pyrimidine dimers. The structure of the DNA changes on all the sites where dimers form and hence, they cannot be properly transcribed.
