The instrument is called fiber optic bronchoscope. It is the instrument that is used to examine the bronchial tree and to remove objects aspirated into air passages. The procedure is called bronchoscopy which allows the doctor to look at the airway through the instrument. During this procedure the doctor examines the throat, larynx, trachea, and lower airways. It also allows the doctor to remove small samples of tissue (biopsy).

Q9. A SimCell has a special membrane that is permeable to alcohol but not to water. This SimCell contains 20% alcohol and 80% wa
Charra [1.4K]

Answer:

The SimCell will expand due to net movement of alcohol into the cell

Explanation:

Since the SimCell is only permeable to alcohol and not water, only alcohol can move in and out of the cell. Hence, if a SimCell that contains 20% alcohol and 0% water is placed in a solution containing 40% alcohol and 60% water, there would be a net movement of alcohol from the surrounding solution into the SimCell till equilibrium concentration of alcohol is established between the SimCell and the surrounding solution.

<em>Therefore, the SimCell will expand due to the net movement of alcohol into the cell.</em>

A nucleotide consists of a phosphate group, a pentose sugar, and a __________________, all linked together by covalent bonds. po
solong [7]

Answer:

d. nitrogen-containing base .

Explanation:

A nucleotide comprises a phosphate group, a pentose sugar and a nitrogenous base (nitrogen-containing base).

A nitrogenous base is a type of aromatic heterocyclic organic compound which essentially has nitrogen in it. The base can be a purine or pyrimidine. Purine nitrogenous bases are adenine (A) and guanine (G) while pyrimidine nitrogenous bases are cytosine (C), thiamine (T) and uracil (U).

Till the time a base is not attached to covalently linked phosphate group and a pentose sugar, it is known as nucleoside. But as soon as we attach any nitrogenous base to the nucleoside, a nucleotide is formed. So it means a nucleotide is nucleoside + nitrogenous base.

Examples are as under:

A nucleotide which has adenine as nitrogenous base is known as adenosine triphosphate (ATP) while a nucleotide which has guanine as nitrogenous base is known as Guanosine-5'-triphosphate (GTP).
