Which shows the correct order in which food moves during digestion?
viktelen [127]
Digestion is of two types, mechanical and chemical. Food first enters the mouth where it is mechanically digested by the teeth and chemically digested by the enzymes in the saliva. Next, food travels to the pharynx and then the esophagus via peristaltic motion of the muscles. Then the food enters the stomach, where chemical digestion is completed. The broken down food is sent to the small intestine for absorption and then the large intestine to have water removed and then be expelled from the body.

The relative strengths of covalent bonds and van der Waals interactions remain the same when tested in a vacuum or in water. How
ziro4ka [17]

Answer:

Water is bolar

Explanation:

One side of the water molecule is slightly positive and the other is slightly negative. Water is made up of two hydrogen and one oxygen atoms. The bond in this arrangement is called a covalent bond. In addition to this, water is also called the universal solvent and is capable of sharing charges with a large amount of ionic compounds when mixed allowing them to be dissolved. In essence the strong bond is reduced. This weakens the ionic and hydrogen bonds in the presence of water. Next, in a vacuum, there are no other electrons to share charges with and the hydrogen and ionic bonds are said to be strong to an immeasurable amount, in some reports, infinity.

iragen [17]
We are given:

2 units of packed red blood cells infused over 1 hour each, so 1 unit per hour
1 unit is equivalent to 250 ml
10 gtt/mL

solve for the volume per unit time:

1 unit per hour / 1 unit /250 mL = 250 mL per hour

The flow rate in drops per minute is determined by:

- converting hours to minutes:

250 mL per hour * (1 hour / 60 minutes) =4.2 mL per minute

-multiplying gtt/ml to flow rate

4.2 mL/min * 10 gtt/mL = 42 gtt/minute

Therefore the final flow rate in drops per minute is 42 gtt per minute.<span />
