<h3>Phototropism</h3>
Yes, the given activity is a correct example which describes phototropism
Phototropism is an adaptation or a survival mechanism undertaken by some plants to receive maximum sunlight in order to prepare more food and energy through photosynthesis.
Explanation:
Phototropism takes place through receptor proteins called phototropins which act as blue light photoreceptors.
Phototropic activity:
Phototropism can best be observed by planting few plants including phototropic plants in pots and keeping them near the window to receive sunlight.
The natural bending of phototropic plants towards the window denotes their inclination towards sunlight.
The growth of sunflower plants facing towards the sun and blooming of lotus flower under sunlight are all examples of phototropism.
Other plants which are phototropic are Phalaenopsis, azuki beans, fungus of Phycomyces species, etc.
Given what we know, we can confirm that the correct option is D, which states that "<em><u>They are used by living things as the </u></em><em><u>main source </u></em><em><u>of </u></em><em><u>energy</u></em>."
<h3>What are carbohydrates?</h3>
- They are the primary source of energy for most cells.
- They are what we refer to as sugars.
- The main example of this is glucose.
- They are formed by monomers called monosaccharides.
Therefore, we can confirm that since carbohydrates are what we refer to as sugars, which include molecules like glucose and this is the main source of energy for most cells, option D is the correct choice.

The four have molecular similarities, but have their own unique traits. The tree indicates that there was a common ancestor (the V at the base). Biomolecular differences are the basis for each branch, but there are similarities between all four organisms. The branches support the idea that each organism has unique traits as determined by their unique DNA and amino acid sequences.
