Answer:

The correct answer is option d, that is, located in the same plane.

Explanation:

The rotator cuff refers to the group of four different muscles and their tendons that offer stability and strength at the time of motion of the shoulder complex. The muscles originate from the scapula and associates with the humerus head, producing a cuff surrounding the glenohumeral joint.  

The rotator cuff muscles are utilized in different extremity motions comprising abduction, flexion, external rotation, and internal rotation. As a group, these muscles are accountable for steadying the shoulder joint, by offering fine-tuning motions of the humerus head within the glenoid fossa.  

They assist in maintaining the humerus head inside the small glenoid fossa of the scapula in order to enhance the range of motion in the glenohumeral joint and prevent mechanical obstruction. In order to retain the humeral head aligned within the glenoidal cavity, the rotator cuff muscles must be aligned in a similar plane.

Below are three different scenarios for comparison. For each scenario, decide if it represents greater or less entropy and great
uranmaximum [27]

Answer:

Entropy is characterized as a level of irregularity or disorder in a system. More the disorder more is the Entropy. The greatest entropy is accomplished when the system is in equilibrium.  

In a similar manner, stability is legitimately relative to entropy. Therefore, more entropy, more is the stability and the other way around.

<u>S.No      Scenarios                Entropy                  Stability </u>

A               Glucose                    Less                   Less

           Carbon dioxide or water      More                   More

B        A messy room              more                    More

               A clean room                      Less                     Less

Current studies on frogs and wildlife indicate that hormonally active agents (HAAs) are __________. a. found in insecticides and
melomori [17]

The right answer is A.

The term "hormonally active agent" (or endocrine disruptor) refers to any molecule or compound chemical agent, xenobiotic having hormono-mimetic properties and described as a cause of physiological abnormalities, and in particular reproductive abnormalities. Some examples are PCB, TCDD, DDT. Some of them were used as pesticides and are now banned for use. Their traces always exist at the soil level due to their persistence.

These agents are most often associated with breast cancer.

When the _______5___ reaches the end of an axon, the neurotransmitter is released, and it diffuses to the muscle cell membrane t
postnew [5]

Answer:

5- action potential 6- receptors 7- calcium ions 8- sarcolemma

Explanation:

This description illustrates the pathway of a action potential traveling along a neuro-muscular junction. this functions as a chemical synapse between a motor neuron and a muscle fibre. It allow the motor neuron to transmit a signal/action potential to the muscle fiber, causing muscle contraction.
