The burial practices of humans have not led to any significant changes in Earth's biome. Matter can not be created nor destroyed. Burial practices lead to burying the dead bodies into the Earth, where they are decayed by the action of several microbes and insects. The organic and inorganic compounds are added to the Earth.

Llana [10]

Answer:

The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.

Explanation:

As you can see in the attached table

1. For the size of the flagella we gave that:

- 241 organisms have long flagella

- 79 organisms have short flagella,

As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.

2. For the number of vacuole we have:

- 247 organisms have one vacuole

- 73 organisms have two vacuole

As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.

Then

Dominant phenotypes = Long flagella and one vacuole

Recessive phenotypes = Short flagella and two vacuoles

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
