If four different snake species with identical food and habitat niches colonize an island at the same time, and one is better able to detect and acquire food than the others, which of the below options will most likely happen over time? he species best able to detect and find food will compete with the others, causing them to occupy smaller realized niches.

The species best able to detect and find food will outcompete the other snakes; it will eliminate the others via competitive exclusion.

All four species will coexist because they will all occupy smaller realized niches due to competition.

One species will persist, but we cannot predict which one; the others will go extinct because of competition.

The fish shown above is a tarpon. it is a fast-swimming and powerful open-water fish. its closest relatives, oddly, are burrow-dwelling conger eels that stay on the bottom. both eels and tarpon developed from snake-like larvae that float in the plankton during the first stages of life. once they mature, tarpon and eels are not found near one another in the ocean. the tarpon and the eel illustrate all of the following except

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening
