Please Help me answer the following answers correctly!!!! Please circle the BEST answer to the following questions. 1) Which is most likely to be true about the interaction between humans and microbes? a. Microbes typically harm humans. b. Microbes and humans depend on one another for survival. c. Microbes and humans do not depend on one another for survival. d. Both a and c 2) Sometimes conditions in our body change (for example, diet, hygiene, pathogens, etc.). The microbes living in and on our bodies usually respond to these changes by: a. dying b. reproducing c. either dying or reproducing d. moving to a different body part 3) A symbiotic relationship is between two or more organisms. In this relationship: a. these organisms live together and benefit from one other. b. one organism is helped and the other organism is harmed. c. one organism benefits and the other organism is neither helped nor harmed. d. All of the above 4) How can taking antibiotics (medicine that fights infections) harm microbes in humans? a. Antibiotics RARELY harm microbes. b. Antibiotics target ONLY disease-causing microbes. c. Antibiotics target MOSTLY disease-causing microbes d. Antibiotics do NOT target disease-causing microbes.Explanation / Answer
AS PER CHEGG POLICY, PROCEEDING TO ANSWER ONLY THE FIRST 4 QUESTIONS/SUBPARTS, THAT IS, QUESTIONS 1 TO 4:
ANSWER 1)
Microbes in the gut region of humans help in digestion and assimilation of nutrients from food.
Hence, it is most likely to be true about the interaction between humans and microbes that:
b. Microbes and humans depend on one another for survival.
ANSWER 2)
When faced with changing environmental conditions, microbes do one of three things based upon the severity of change. Their responses range from adapting to reproducing. Dying is simply a consequnce of failing to adapt. It is not a response from their side. It is unlikely for them to be able to move to a different body part as they are uniquely suited to the original milieu and might be treated as antigens in other parts.
As such, upon changing body conditions, microbes living in and on our bodies usually respond to these changes by:
b. reproducing
ANSWER 3)
Symbiotic relationships exist between two or more organisms wherein each is helped by the other. In this relationship:
a. these organisms live together and benefit from one another.
ANSWER 4)
Antibiotics are generally broad spectrum molecules that kill off a wide range of structurally or metabolically similar microbes. As such they are not specifically designed to kill off only the bad microbes and might act upon certain good microbes that share the same feature. The good microbes might not illicit a bad function because that structural or metabolic unit might be inactivated, an intermediate in a pathway or simply vestigeal. As such:
c. Antibiotics target MOSTLY disease-causing microbes.
