One of the negative impacts of eutrophication and increased algal growth is a Loss of oxygen known as anoxia
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.
Answer:
The statement is false.
Explanation:
I actually had this question on a test, and I got it wrong when I put true.
What your cells have to help overcome a problem of high activation energy are called enzymes. Enzymes are proteins that lower the activation energy of a reaction. In doing this, enzymes increase the rate of a reaction, helping it to occur faster. However, enzymes are not consumed in a reaction; they simply help it to occur.
Enzymes make things easier for your cells to work properly and help chemical reactions occur. There are hundreds of different kinds of enzymes in your cells, which all participate in different types of reactions. Enzymes can break molecules apart, build or add molecules, and even rearrange them.
In lowering the activation energy of a reaction, enzymes decrease the barrier to starting a reaction. It's important to note, however, that the change in energy remains the same between the start and end of a chemical reaction.
Lead.
"Due to insufficient water treatment, lead leached from water pipes into the drinking water, exposing over 100,000 residents to elevated lead levels."
