Climate, geology, topography, hydrology and soils all play a part in the formation and function of watersheds. These factors provide habitat, nutrients, flow and water quality that aquatic organisms need to survive.
This might not be very accurate but.. I would assume that individuals should be concerned about toxicity levels and it’s overall nutrition. If there was no testing done on this plant before it’s release it could cause severe damage and possible allergic reaction to whoever consumes it. You should also worry about the cleanliness for there are high chances of getting some sort of parasite
Answer:
We have just seen that pathogens constitute a diverse set of agents. There are correspondingly diverse ranges of mechanisms by which pathogens cause disease. But the survival and success of all pathogens require that they colonize the host, reach an appropriate niche, avoid host defenses, replicate, and exit the infected host to spread to an uninfected one. In this section, we examine the common strategies that are used by many pathogens to accomplish these tasks.
Explanation:
The first step in infection is for the pathogen to colonize the host. Most parts of the human body are well-protected from the environment by a thick and fairly tough covering of skin. The protective boundaries in some other human tissues (eyes, nasal passages and respiratory tract, mouth and digestive tract, urinary tract, and female genital tract) are less robust. For example, in the lungs and small intestine where oxygen and nutrients, respectively, are absorbed from the environment, the barrier is just a single monolayer of epithelial cells.
Skin and many other barrier epithelial surfaces are usually densely populated by normal flora. Some bacterial and fungal pathogens also colonize these surfaces and attempt to outcompete the normal flora, but most of them (as well as all viruses) avoid such competition by crossing these barriers to gain access to unoccupied niches within the host.

Multicellular organisms are able to achieve homeostasis because they cells are specialized in function and work cooperatively with one another.
