Design a controlled experiment to determine whether earthworms change the forest ecosystem.
Orlov [11]

"The experimental hypothesis may be that if Asian worms are introduced into a <u>deciduous forest</u>, the soil's nutritional composition will alter. The control group would consist of a region of the forest that has been worm-free in some way. But in order to serve as a control, this forest would experience the same amount of sunshine, heat, and precipitation. In order to determine if Asian worms actually have an impact on the forest ecology, the scientists could then analyze the amounts of nitrogen, phosphorus, and sulfur in the two portions of the forest."

Deciduous forest- A deciduous forest is one that is mostly made up of trees that shed their leaves in the fall.

What three elements do all macromolecules share? Explain how the chemical properties of lipids, nucleic acids, proteins, and ami
Natasha2012 [34]

Answer

Macromolecules in human body

             The macromolecules found in human body are:

1. Carbohydrate,

2. Proteins

3. Lipids, and  

4. Nucleic acids.  

Elements they common share

             All these macromolecules have three elements in common which are:

1. Carbon

2. Hydrogen, and

3. Oxygen.  

                   These elements constitute about 95% of human body.

Difference in Chemical properties

                    Carbohydrate is composed of glucose monomers, which may have aldehyde functional group or ketone functional group. Protein is composed of monomers called amino acids. Each amino acid has carboxylic functional group, amino group, alkyl or aryl group and hydrogen atom. Lipid is composed of fatty acids and glycerol. While nucleic acid is composed of monomer called nucleotide. Each nucleotide is composed of pentose sugar, phosphate group and nitrogenous group. Due to the presence of different functional groups all these macromolecules have chemical properties different from each one
