The path of energy flow from the sun to the humpback whale is as follows:
- Sun---> Plankton ---> Small fishes ---> Humpback whale.
<h3>What is energy?</h3>
Energy is the ability to do work.
The primary source of energy on the earth is the sun.
The energy from the sun is used by producers to produce food on which other organisms depend on.
The energy from the sun gets to the humpback whale through producers such as plankton.
The path of energy flow from the sun to the humpback whale is as follows:
- Sun---> Plankton ---> Small fishes ---> Humpback whale.

Answer:
B. the role of creativity in scientific discovery
Explanation:
Watson and Crick's ball-and-stick model of DNA demonstrates the importance of creativity in science. Creativity involves having a questioning mind that is always searching for answers and which employs logical reasoning to arrive at these answers. After Rosalind Franklin obtained an X-ray diffraction of DNA, Scientists Watson and Crick expanded on this knowledge by creatively organizing ball and sticks in a manner that represenseted the structure of the DNA.
This simple creative act led to more discoveries about the DNA including the facts that their was a pairing wherein Adenine paired with Thymine and Cytosine paired with Guanine. They also found that the DNA structure could be unzipped and that copying was also possible. They used the simple things around them to arrive at this conclusion. This is an example of the importance of creativity in science.
Not all DNA codes for proteins
Explanation:
- DNA (Deoxy Ribonucleic acid) is the genetic material present in all the eukaryotes.
- An experiment conducted in the 1960s proved that most parts of DNA are composed of long strings of repeated sequence which does not code for proteins.
- The process involves in coding for a protein are the transcription of DNA to RNA, then translation followed by protein synthesis. There are enzymes involved in these processes.
- As per the latest study, it states that only 1 per cent of genes code for proteins rest 99 per cent is called the non-coding DNA.
