Beaches are monitored to protect public health. Waterborne pathogens can cause illnesses. Which of the following is not a common type of pathogen at the beach?
Bacteria
Protozoa
Viruses
Worms
ALL these microorganisms can represent common types of pathogens at the beach. In consequence, it is imperative to take precaution measures to avoid infections.
The sand at the beach may contain dog feces, which is known to transport Toxocara canis, a parasite roundworm able to infect humans.
Moreover, samples of beach sand may also contain different types of pathogenic bacteria (e.g., Staphylococcus species, E. coli, Enterobacteriacea, etc) and viruses (e.g., enteroviruses, hepatitis A, Norwalk viruses, reoviruses, rotaviruses, etc).
In consequence, it is imperative to wash hands with soap and water when touching beach sand that is suspected to be contaminated.
Finally, marine water may also be contaminated with different zoonotic protozoa such as, among others, Giardia, Cryptosporidium and Toxoplasma.

Three kinds of _________ molecules carry out genetic instructions for the production of proteins?
Just for the fun of it, someone walking along the shore in Beaufort, South
Carolina, throws a bottle with a message in it into the sea. Some time later,
someone in Perth, on the west coast of Australia, finds the bottle.
Referring to map, trace the path the bottle probably took! Make sure to
reference specific currents on your path.
The currents that carry the bottle from South Carolina to Peth are the West Wind Drift and the South Equatorial Current.
According to the information provided by the map, it can be inferred that the bottle that is thrown into the sea in South Carolina, USA and arrived in Perth, Australia took the following route:
It traveled down the Atlantic Ocean from the United States to the West Wind Drift current. Once there, it is transported from the west to the east, passing through the lower part of Africa and Asia until it reaches the Indian Ocean. When it reaches the Indian Ocean it is carried by the South Equatorial Current with a northeast direction. In this direction it reaches the coast of Peth, Australia.

Considering that cells vary in shape,what other dimensions or parameters of the cell could be used to estimate cell size?
Answer:
Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall. Each of these three factors is highly dynamic, meaning they are constantly in flux or can be suddenly changed. This dynamism is how cells can vary in shape.

Yeast cells are eukaryotic. What does this mean? in your own words
Answer:
Yeast cells are eukaryotic which means that they have a membrane-bound nucleus that holds their genetic information.
Eukaryotic cells also contain membrane-bound organelles such as:
Mitochondria responsible for energy productionRibosomes responsible for protein synthesisCell wall that protects the cell from the environmentThe Golgi apparatus that packages proteinsIt also means that their cellular complexity is different from Prokaryotic organisms which lack membrane-bound structures for example the nucleus. Prokaryotic cells are mostly small and simple and Eukaryotic cells are typically a lot bigger and more complex.

so that our body won't contain all the bad waste and allow all the good nutrients to help out our body.
The body of an organism utilizes the nutrient and the energy derived from the food.
The digestive system of an organism is accountable for breaking, digesting, absorbing and assimilating food.
The cells in our body perform biochemical reactions in which some of the substances are harmful or fatal to the body cells if gets stashed.
