Answer:
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Answer:
As the DNA is present in the nucleus, there is compartmentalisation and the process becomes more efficient without the interaction of external bodies. The membrane of the nucleus protects the DNA from injuries.

Given above…
<u>Answer:</u>
<em>The second structure, the ribbon model of protein structure is most useful for studying the interior shapes formed by the folds of protein.</em>
<u>Explanation:</u>
The ribbon model of protein structure is the representation of structure of protein in 3D schematic diagram where colour coding for the different secondary structures can be done for better understanding.
In this model side chain is not shown. Generally, this model of structure is used for the comparison of overall structure of two different proteins.
I think Its the option that says that one of the reactions absorbed more energy because in the diagram the activation energy is shown to be greater for the blue pathway.
