A cell with a large surface area or with microvilli (which increase surface area) are specialized for absorption. Many cells have different protein markers on their surface to accept certain specific hormones and allow them into the cell, like muscle cells reacting to adrenaline. Muscle cells are long and able to contract, allowing for overall muscle contraction and body movement. 

I guess the hormone part I mentioned applies to chemicals; endocrine cells produce hormones that other cells would not. 

For organelles, muscle cells don't have many of the organelles that other cells do because of their very specialized functions. 

I hope this helps, it would literally take volumes of text books to answer this question completely.

You have just delivered a premature baby. Your assessment reveals that he is breathing adequately; however, his heart rate is 90

Answer:

The answer is letter B, keep him warm and ventilate with BVM.

Explanation:

In order to know more about the answer, let's check out the meaning of "Premature Baby" first.

Premature Baby- a baby born through premature birth (fewer than 37 weeks). Babies are normally born at the usual 40 weeks. Health problems may occur with premature babies, thus it is very important to monitor them.

In the situation above, the premature baby's heart rate is only 90 beats/min. A resting heart rate for a newborn infant is 130-150 beats per minute. This means that the baby above has a slow heart rate. In order to increase the hear rate, it is important to keep the baby warm and to ventilate with a "Bag Valve Mask" (BVM). An increase in internal temperature increases the heart rate. Increasing ventilation will also help increase the heart rate.

Remember: Inhalation increases the heart rate.
