It couldn't be analysed chemically because it's chemical composition is to complex. It would be hard for us to analyse them because once it has been removed from the organism, it ends as protoplasm only.
The correct answer is false and here is why:
Clear cutting refers to the cutting of trees, specifically all of the trees in one select area. Replanting is not done and this leads to deforestation.
Controlled burns have a completely different affect. They burn the under brush to help keep the soil rich with nutrients, plus they also help to prevent large crown fires that burn down whole forests from happening.
Clear cutting is a bad thing and controlled burns are a good limiter for a forest.
A. Consumers cannot produce their own food source so they have to eat other animals.

Answer is 55%.
Blood is fluid connective tissue that consists of two main components, plasma and formed element. Blood plasma is a clear extracellular fluid, which is a mixture of proteins, enzymes, nutrients, wastes, hormones and gases. Formed elements are made up of the blood cells (red blood cells and white blood cells) and platelets. All formed elements are cells except for the platelets, which are tiny fragments of bone marrow cells.
The formed elements can be separated from plasma by centrifuge. On separation of blood components, it is evident that formed elements make up 45% of total blood volume while the plasma makes up 55% of the total volume.
