Answer:
To make sure that the experiment is accurate, the scientist must make carry out an appropriate observation, which would lead to the formation of good hypothesis. Good experimental method is an other criteria to look forward for the accurate experimental results. Methods are applied in collection of data and other things and in compiling results using statistical methods to carry out an accurate experiment.
Models show systems that are large, small or complex.They make it easy for study through zooming in an area in a large system.They provide visual presentation of an object or a system that has been created through experimental data.
Explanation:
A model is a representation of an idea, a process or an object in a system used by a scientist to describe a phenomenon that is difficult to be experienced directly.The goal of a model is to ensure that the presentation is done in a logical and objective way.

<h2>Answer:</h2>
The mRNA is important for carrying the sequence information of amino acid in poly peptide chain. While tRNA carry the specific amino acids from cytoplasm to the poly peptide chain according to the message in mRNA.
<h3>Explanation:</h3>
- mRNA is the message from the DNA in the form of specific nucleotide sequence.
- mRNA is complementary sequence of nucleotide formed in the process of transcription in nucleus.
- While tRNA are also produced in the nucleus from the DNA but they do not contain any message for the poly peptide production. While they are transported to cytoplasm and their function is the transport of amino acid from cytoplasm to growing poly peptide chain.
