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.

A protostar forms once the nebular cloud condenses and the core begins to heat. To heat is the answer hope this helps you!!
Answer:
Atoms have three particles: protons, electrons, and neutrons. The nucleus contains protons and neutrons. The outside regions of the atom are called the electron shells and have electrons.
Explanation:
hopefully this helps you. :)

The TRUE statements are 'proteins often have more than one transmembrane domain'; 'they are regions of a transmembrane protein that actually pass through the lipid bilayer' and 'they are usually shaped like alpha-helices'.
A transmembrane domain is a membrane-spanning region within a protein. The transmembrane domains are hydrophobic regions that can be inserted into the cell membrane.
The transmembrane domains are usually shaped like alpha-helices.
This secondary structure (alpha-helices) causes the amino acid R-groups to project radially, thereby these side chains can interact with each other.
Proteins need only a single transmembrane domain to be anchored to the membrane, but they often have more than one.
For example, Acyl-coenzyme A cholesterol acyltransferases 1 and 2 (ACAT1 and ACAT2) have multiple transmembrane domains.
The transmembrane domains are regions of a transmembrane protein that actually pass through the lipid bilayer.
These domains contain amino acids with hydrophobic R-groups that pass through the membrane and interact with the hydrophobic tails of the fatty acid chains present in the lipid bilayer.
The transmembrane domains anchor transmembrane proteins to the lipid bilayer.
The interactions between amino acids of the transmembrane domains and fatty acids in the lipid bilayer help to anchor transmembrane proteins and stabilize the cell membrane.

Sometimes, the dark spots on the marshmallow can fall off of the marshmallow. This means that, the system does not need to include the pieces that fell when determining the mass before and after.
