1. Compare and contrast anaerobes. Why were no microbes noted upon aerobic and anaerobic culture?2. Investigate the properties and characteristics of M. Fortuitum. Where is this organism typically found (reservoirs)?3. Why must the Acid Fast Stain be performed to identify organisms of the Genus Mycobacterium?4. Why did Dr. Chan prescribe two antibiotics rather than one?5. How does doxycycline kill bacteria ( cellular target)?6. Why were the antibiotics prescribed for an extended period of 4 months?7. No organisms were noted upon Gram Staining, yet the Enrichment culture yielded M. Fortuitum after several days. Provide an explanation.

hehe

Explanation:

every el niño cycle is different. every year.

the right option is; decreased genetic variation  

decreased genetic variation describes the effect of this environmental change.

genetic variation is the naturally occurring genetic diversities or differences between organisms of the same species in a population. genetic variation allows the survival and adaptability of a species when they encounter changing environmental conditions. when an endangered species reduces, it loses genetic variation which may not be restored even if the species rebound and will only be recovered through the gradual collection of mutations over many years.
