If a snake species were introduced to an ecosystem where it had no natural predators,
what long-term effect do you predict the snakes would have on the population
dynamics of the ecosystem?
O They would compete with native snake species for resources, causing a decline in native snake
populations and possibly extinction.
O They would serve as a food source for predators of native snakes, causing an increase in native
snake populations.
O They would form mutualistic relationships with native snakes, since they would occupy the
same niche in the ecosystem.
O They would breed with native snakes, resulting in an increase of biodiversity in the ecosystem. I'm taking a quiz and I need help now

It’s the first one. Because they have NO predators, the original snake wouldn’t be one for them.

In order to understand the problems of unwanted infertility in a country — the gambia — where the desire for children and the fertility is very high, a population-based survey was undertaken. all infertile women in 24 randomly selected enumeration areas were assessed. the study included a review of the problems faced and coping mechanisms employed by infertility clients and types of health care available for infertile couples in the different types and levels of the formal and traditional health system. half of the infertile couples failed to seek formal health care, and they have to reach a certain level of care in order to be properly managed. alternative care is often sought. child fostering is also a frequent solution to childlessness. in-depth interviews revealed that traditional care like healers and spiritual leaders are frequently consulted long before formal health care. this delay could be a problem in those cases where infertility is caused by infections.
