in some cases, people who test positive for
genetic testing can receive preventive
treatments. for example, people who test
positive for the breast cancer genes brca1
and brca2 can have a preventive
mastectomy (breast removal surgery) before
they develop the disease. in other cases, no
preventive treatments are available, but
frequent monitoring can detect a
disease earlier, when it's more easily treated.

what ethical or professional concerns does a
health-care professional need to address
when he or she has a patient who wants to
prematurely treat a genetic disease? do you
think genetic testing should be part of normal
preventive healthcare? why or why not?

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
