Distillation is a method for separating the components of a mixture based on boiling point differences
Your answer is A) Recombinant DNA. I just took this quiz. Thanks
In protains, DNA, RNA, and chlorophyll.
The question is incomplete as it does not have the options which are:
- there was no sulfur compound added to the medium, that could be used as an electron donor.
- no oxygen was added to the medium so the organism died.
- there is some inhibitory chemical that is preventing the growth of the bacterium.
- you were using the wrong type of sunlight as the energy source for the bacterium.
Answer:
There was no sulfur compound added to the medium, that could be used as an electron donor.
Explanation:
In the given question, the bacteria which are found in the pond uses light energy to use carbon dioxide and form the glucose molecule. These bacteria are known as phototrophic bacteria.
The process of photosynthesis requires an electron donor and an electron acceptor to use molecule.
The organism when provided the light and carbon dioxide artificially in a culture, the bacteria were not able to grow. The reason for this could be accounted as that there was no electron donor found in the media like sulfur which could donate the electron during the chain reaction.
Thus, the selected option is correct.
Chloroplasts
Chloroplasts capture the energy in sunlight and use it to synthesize energy-rich carbohydrates. This food made by chloroplasts provides the chemical energy needed by all forms of life. Mitochondria help cells to extract the energy in food molecules efficiently to power cellular activities.
