Biology

Leokris [45]3 years ago

Answer: Energy is the ability and capacity to do work or act upon something. Electrical energy is the movement of electrons that is used to power something to do a action. One source of energy if you are talking about the body is your lungs taking in oxygen, the oxygen is distributed amongst your body into your blood cells to provide energy. In an electrical viewpoint, a source would be a lightning bolt, this is created when positive protons are attracted to the negative particles on the ground, which leads it to shoot down rapidly making a shift of energy and making a loud sound and also bright light as they collide to make a burst of power.

Which of the following is not required for the proper use of molecular beacons?
arlik [135]

Answer:

b. Detachment of a separate hybridized probe molecule from the template DNA

Explanation:

Molecular beacons are a type of genetic probe that enables the hybridization of oligonucleotides. These molecules have a flourishing component that binds to a nucleotide sequence and allows the identification of this nucleotide sequence in DNA or RNA without the release of radioactivity. For the use of these molecular beacons to be possible, one needs complementarity between the model DNA and the probe sequence,  illumination of the hybridized beacon to detect fluorescence and proximity-based quenching of the fluorophore prior to beacon hybridization.

The lungs remain inflated because ___________.a. intrapleural pressure is exactly equal to atmospheric pressure b. intrapleural
kkurt [141]

Answer:

Option C,  Intrapleural pressure is less than intrapulmonary pressure

Explanation:

During inspiration, the air enters the lungs due to lower pressure in the intrapulmonary or intra-alveolar  than the atmospheric pressure. During quite respiration, the intrapulmonary pressure reduces to a pressure that is 3 mm Hg lower than that of atmospheric pressure. During quiet expiration, the intrapulmonary pressure rises up to a pressure that is 3 mm Hg higher than that of atmospheric pressure. This leads to lack of air in the intrapleural space thereby producing intrapleural pressure which is lesser than that of intrapulmonary pressure.  

This difference in pressure (i.e higher pressure with in the lungs than the atmosphere)  causes lungs to remain attached to the chest wall and hence looks inflated.  

Hence, option C is correct
