Answer:
The correct answer is B.
Explanation:
Asthma is a chronic inflammation of the airway, it consists of inflammation of the bronchi, which are responsible for bringing air to the lungs, producing an obstruction of these, which deals with recurring episodes of bronchial hyperresponsiveness and a variable obstruction to air flow. All these inflammatory changes can happen abruptly (Acute Asthma) or slowly and continuously (Chronic Asthma). When they appear abruptly it is called "crisis" or acute asthmatic attack. Both the acute and chronic forms can be highly variable in terms of intensity or duration; sometimes they yield alone or with special treatments.

Answer:
DNA replication.
Explanation:
DNA replication is a complex process in which the parent DNA transfers its data to daughter DNA. The DNA is separated in the double helix prior to transfer. The three main steps in DNA replication are initiation, elongation, and termination. In initiation, the DNA breaks down and the strands separate. During elongation, new DNA molecules form by single strands adding complementary bases. Finally, termination is when two idential DNA molecules are made each containing a new strand of DNA.

<u>Answer:</u>
<em>Earthworms are very sensitive towards the odor. </em>
They use it for locating the food in the soil. Because earthworms are dependent upon microorganism in the soil, they must be sensible for the <em>presence of any food around them if they do not respond the odor then they may die. </em>
Earthworms have the escape response so they quickly respond the external stimuli at the part they are stimulated. <em>With the increasing frequency of stimuli at the same part they slowly decrese the response towards it.</em>
