Which of the following is a feature of the lymphatic system? a. it is composed of a mucus-like substance. b. it picks up and transports dietary lipid. c. it serves to transport fat- and water-soluble vitamins to the heart. d. it funnels nutrients to the liver via a one-way pump.

B. It picks up and transport dietary lipid.

Explanation:

A lymphatic system plays an important part of immune system and has many functions to perform.

1- It is not a closed system and is responsible for removal of interstitial fluids.

2- It absorbs and transport fatty acid from the digestive system.

3- It helps to transport white blood cells. ( To and fro form lymph nodes into bones).

4- It pick up and transport dietary lipid.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
