We can reduce air pollution by using public transport instead of private vehicles when possible, this can reduce the gas released from private cars. We can reduce energy consumption by setting air conditioner to a suitable temperature such as 26°C or use fan instead. Also make sure we turn off all the electrical appliances when we leave a place.
If the results of an experiment have different conclusions, something must have changed. these are called **variables**. if more than one variable is changed, the result would be different. because the total conclusion is different, it is a hypothesis, because it is not universally true.
Answer:
This question is asking for the polymer and monomer of nucleotide and protein respectively.
The answer is:
Protein - monomer is AMINO ACID
Nucleotide - polymer is NUCLEIC ACID
Explanation:
There are four major biological molecules found in nature namely: protein, carbohydrates, fats and oil, nucleic acid. These biological molecules are, however, complex and polymeric in nature and like every other polymer, they must contain monomers that make up their structure.
- PROTEINS are made up of monomers called AMINO ACIDS.
- CARBOHYDRATES are made up of monomers called MONOSACCHARIDES.
- LIPIDS are made up of monomers called FATTY ACIDS.
- NUCLEIC ACIDS are made up of monomers called NUCLEOTIDES.
