The relationship between science and society is in contemporary societies has been characterized by an evolution from an initial stage based on diffusion of scientific literacy to the last stage of confidence and trust crises.
The best question for this experiment is How does the composition of the soil affect the pH of the rainwater?.
<h3>What are the best factors being studied?</h3>
The main factors based on the description are:
- The pH of the rainwater: This is the factor manipulated by the researcher.
- The aluminum concentration: This is the factor researchers are evaluating.
<h3>What is the best question?</h3>
The best question would be one that relates the main two factors. Based on this, the best question would be: "How does the composition of the soil affect the pH of the rainwater?".

Answer: 1) DNA ( deoxyribonucleic acid) is considered as the genetic material of living organisms ( that is passed from parents to next generation). It determines the structure of protein that carry out essential function of life.
- For this, DNA possesses instructions in the form of specific nucleotide sequences. First it undergoes transcription, in which genetic information from DNA is passed to mRNA ( messenger RNA), which is finally converted to specific protein through translation.
2) The importance of DNA determining proteins is that the proteins, which are formed, corresponds to specific cellular activities ( such as digestion of proteins, fats, carbohydrates) as well as the characteristics/ traits ( like color of skin, color of eyes) of the organism.
In this way, traits are passed from parents to their offspring through genetic material.
Trichomonas vaginalis can be distinguished from other parasitic protozoa because it is responsible for urethritis and vaginitis in humans. It has an undulating membrane, it can infect the vagina in women, and it is often transmitted by sexual contact, so it can be considered an STD. Given that it can cause many complications in a woman's reproductive system, it should be treated immediately.
