The answer is <span>c.CS; US.
In classical conditioning, a new behaviour is learned via association. The stage before conditioning involves: 1. unconditioned stimulus (US) which produces an unconditioned response, and 2. neutral stimulus (NS) which has no effect on a person and produce a response only when paired with </span>unconditioned stimulus. During conditioning, neutral stimulus (NS) and unconditioned stimulus (US) pair and neutral stimulus becomes a conditioned stimulus (CS). In other words, <span>the ns becomes a <u>CS</u> after it reliably signals the impending occurrence of the <u>US</u>. </span>
HeterotrophA heterotroph is an organism that ingests or absorbs organic carbon in order to be able to produce energy and synthesize compounds to maintain its life
Parallel
In a parallel arrangement, the length of the fascicles runs parallel to the long axis of the muscle. Such muscles are either straplike like the sartorius muscle of the thigh, or spindle shaped with an extended belly, like the biceps brachii muscle of the arm. However, some scientists classify spindle-shaped muscles into a separate class asfusiform muscles.
Pennate
in a pennate pattern, the fascicles are short and they attach obliquely to a central tendon that runs the length of the muscle. Pennate muscles come in three forms:
<span><span>Unipennate, in which the fascicles insert into only one side of the tendon, as in the extensor digitorum longus muscle of the leg. </span><span>Bipennate, in which the fascicles insert into the tendon from opposite sides so the muscle “grain” resembles a feather.
The rectus femoris of the thigh is bipennate. </span><span>Multipennate, which looks like many feathers side by side, with all their quills inserted into one large tendon. The deltoid muscle, which forms the roundness of the shoulder is multipennate.</span></span>
Inhalation is the process that allows air to enter the body while exhalation allows air out of the body. During inhalation, the diaphragm and the rib muscles contract, increasing the volume of the lungs. Air enters the nose or the mouth and flows down the trachea, bronchi, and bronchioles and into the alveoli. On the other hand, during exhalation, the diaphragm and the rib muscles relax, decreasing the volume of the thoracic cavity, Air leaves the alveoli and flows up the bronchioles, bronchi, and trachea and exits through the nose or the mouth.
