PLS I WILL GIVE YOU BRAINLY What effect I think this new bacteria will have on patient 23's overall health
Answer:
Gut bacteria are an important component of the microbiota ecosystem in the human gut, which is colonized by 1014 microbes, ten times more than the human cells. Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function. However, they can also be potentially harmful due to the change of their composition when the gut ecosystem undergoes abnormal changes in the light of the use of antibiotics, illness, stress, aging, bad dietary habits, and lifestyle. Dysbiosis of the gut bacteria communities can cause many chronic diseases, such as inflammatory bowel disease, obesity, cancer, and autism. This review summarizes and discusses the roles and potential mechanisms of gut bacteria in human health and diseases.

a) (5 Points) Why does food not spoil as fast when it is refrigerated as it
would at room temperature?
b) (5 Points) Meat begins to feel slimy and it smells when it is spoiled due to
a decomposition reaction with oxygen and carbon dioxide. Why would
meats spoil less rapidly when left unsliced?
Answer:Temperature affects storage time and food deteriorates faster at higher temperatures. Microorganisms grow rapidly at room temperature . Thus to slow microbial growth, enzymatic and oxidative processes, food must be stored at room temperature.
Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. ... Because of its smaller surface area, the unsliced meat would have less collisions and therefore, a slower reaction rate.

Answer:
on your own?
Explanation:
it sticks better in your head once you fail
im sorry i dont know this i really need points for my maths test
Answer:
It depends on the situation. Most things are better learning from others because others can see what you cant. On the other hand there are some situations were only you can learn from. Take pain as an example. Others can talk about pain as much as they would like but your body dosent know what that feels like unless it feels it on its own and learns from it. An example of learning from others would be smarts such as math, science, history and so forth.
