Answer:
The oxygen atoms have electrons more often than hydrogen.
Explanation:
Answer:
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Explanation:
There are four major biological molecules called biomolecules in nature namely; carbohydrates, proteins, nucleic acids and lipids. These four molecules form the bedrock upon which life is built. The biomolecules mentioned above are POLYMERS formed as a result of the combination of two or more simpler molecules called MONOMERS in a process called CONDENSATION.
The monomer of each polymeric biomolecule is as follows;
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Answer:
Active transport moves molecules and ions from lower concentration to higher concentration, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Explanation:
Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Heterotrophs help in maintaining a balance in the ecosystem by providing organic compounds for autotrophs. Certain heterotrophs such as fungi help in reducing decomposed plant and animal material. This recycling activity is important in reducing waste in the environment.
