Sexual, this is because during sexual reproduction both DNA of the parents is mixed to create an offspring.
Asexual reproduction is almost like a copy of the parent, there is no external DNA going into the production of the offspring.
Answer:
Test Tube 2 (<em>S. sonnei)</em>
Explanation:
Triple sugar iron agar test is the microbiological assay used to test the fermentation reaction performed by the bacteria. The fermentation process differs based on substrate and the acids formed as a byproduct.
The test is based on the byproduct formed as a result of fermentation. The test tube contains 1% lactose, 1% sucrose and 0.1 % glucose, ferrous sulphate, phenol red pH indicator.
When the bacteria ferment any of the three sugar, the medium turns yellow.
In test tube 1- The tube shows pink slant, pink butt and no black precipitate which indicates that no fermentation took.
In test tube 2- the tube shows pink slant, yellow butt and no black precipitate due to fermentation of Glucose only due to alkali acid reaction.
In test tube 3- the tube shows yellow slant and yellow butt which shows that glucose and either lactose or sucrose has been fermented.
Thus, test tube 2<em> (S. sonnei</em>) is the correct answer.
Holding your breath while ascending can lead to all of the above options.
Surfacing excessively fast or holding the breathing while swimming to the surface can make the air in the lungs expand which is known as pneumonic barotrauma. This might break lung tissue, which can prompt gas bubbles to be delivered into the blood vessel dissemination (arterial gas embolism).
The air in the lungs becomes risky when an individual ascends. On the off chance that somebody holds their breath while rising to the surface, the lungs and the air inside them extend as the water pressure decreases. Since that air has no place to escape, it continues to expand against the walls of the lungs, no matter what the organ's capacity.
