A team of students is performing an experiment to determine how the speed of a reaction between HCl and Na2CO3 changes with temperature. The aspect of the experiment that does not have to be kept constant would be the initial concentrations of the reactants. Hope this helps. Have a nice day.
Number 1: The Circulatory System is a vast network that contains organs and vessels.
number 2: Arteries have a thick wall which helps a powerful pressure from the heart.
number 3: Without the Circulatory System the body wouldn't be unable to maintain a internal environment.
number 4: The Circulatory and Respiratory system both have gas to help a or animal live in there internal environment.
number 5: Blood vessels brings oxygen to the tissues and absorbs carbon dioxide and other waste products to clear the lungs. And with out oxygen the tissues won't absorb carbon dioxide to clear out the lungs.
number 6: D
Answer:
1. Casting
2. Open reduction and internal fixation
3. Open reduction and external fixation
Explanation:
Casting is the process of making use of plaster-of- Paris to cure a fracture.
Open reduction, and internal fixation can be described as a situation whereby surgery is used to repair the fracture-frequently, and involves the use of metal rods, screws or plates to repair the bone. These things remain in place, under the skin, after the surgery. This procedure is adopted when the complicated fractures are not able to be realigned (reduced) by casting.
Open reduction, and external fixation is known to involve surgery to repair the fracture, and placement of a external fixation device on the limb with the fracture. This device is an external frame which supports the bone and hold it in the correct position while it is healing.
the answer to this problem is c
