Answer:
How do you work out energy transfer in a food chain?
Within the food chain energy can be passed and transferred from one organism to another. Whilst mammals get their energy sources from food – whether this be eating other animals or eating vegetation; plants get their energy from photosynthesis. Energy is passed between organisms through the food chain.
The correct answer is 50.
Proteins are complex biomolecules made out of amino-acids bound together with peptide bonds. They can be comprised out of thousands of several polypeptide chains with thousands of amino-acids organised in complex structures. But, some of them can contain only around 50 amino-acid and still posses all of the complex traits of an protein.
Some polypeptides contain only 3 amino-acids, but technically they are not classified as proteins due to a big functional and structural differences between a simple polypeptide chain and a protein. Proteins are made out polypeptide chains, but this is only the primary structure of an protein. the polypeptide chains in a protein are organized into complex 3D structures that give them novel traits and complexity as compared to plain polypeptide chains.
The step of the scientific method mentioned in the question is COLLECTING AND RECORDING DATA.
The scientific method is the technique used by scientists to investigate observed phenomenon and it is made up of series of steps. The steps include: observation, formulation of hypothesis, conduction of experiment, analysis of data obtained and drawing of conclusion. During the process of conducting experiments, scientists have to collect and record data. it is this data that will be analysed at the end of the experiment in order to form appropriate conclusions.
