Ethan has been eating salads without first washing the lettuce. He risks ingesting E-Coli and Salmonella bacteria.
- You could inhale dangerous bacteria from the soil or pesticides used on the produce in the fields if you eat unwashed produce. Furthermore, it's possible that you'll consume bugs that were collected with the produce.
- Animal-based foods like meat, poultry, eggs, dairy products, and shellfish are frequently the cause of food poisoning in humans.
- Fruits, vegetables, and other raw foods, however, can potentially be polluted and sicken people if they aren't rinsed beforehand.
- Fruits and vegetables that are the safest are cooked; those that are the next-safest are washed.
- Prevent eating unwashed fresh food. Fresh produce has many health benefits, but eating raw fruits and vegetables occasionally puts you at risk for food poisoning from pathogens including Salmonella, E. coli, and Listeria.

Answer:
DNA:
- is a single molecule that can be over 10,000,000 nucleotides long
- is usually double stranded
- includes the base thymine
- is the genome for prokaryotic organisms
RNA:
- can be translated into a protein
- is usually single stranded
- includes ribose sugar
- is a single molecule that can form a complex secondary structure
Explanation:
Deoxyribonucleic acid (DNA) is the hereditary genetic material of both prokaryotic and eukaryotic organisms, while RNA is the genetic material of many viruses. DNA is a double helix molecule composed of four types of nucleotides: a nitrogenous base (Adenine, Thymine, Cytosine and Guanine), a five-carbon sugar (i.e., deoxyribose), and a phosphate group. On the other hand, RNA is usually a single-stranded molecule whose nucleotides contain ribose sugars and Uracil bases replace Thymine bases. During translation, a type of RNA molecule referred to as messenger RNA (mRNA) is used as template to direct the synthesis of a polypeptide chain (protein). This RNA molecule can fold to form stable double-stranded RNA hairpins (i.e., secondary structures).
Copper is considered to be a non-renewable resource as it takes a long amount of time for the copper deposits to form.
