Answer: a. fish that eat shrimp.
Explanation:
The PCB's are said to contaminate plankton which then pass them along the food chain including to shrimp which eat plankton. The shrimp will therefore be expected to have higher levels of PCB than plankton because the shrimp eat multiple infected plankton thereby accumulating PCB in their system.
Fish that then eat the shrimp will therefore have even larger amounts of PCB than the shrimp for the same reason as above. Eating the fish would therefore present the most contaminated source to the woman.
Answer:
28 pounds
Explanation:
In the first year of life, the pediatrician monitors the baby's weight gain, as this phase is fundamental for its development. In the first two months, he gains more weight than ever. As it grows, the pace slows down.
In a healthy baby with adequate levels of nutrition, it is normal for the weight to triple by the end of the first year of life. Following this principle, at 2.5 years of age, the baby's weight should quadruple, considering that this baby is healthy and consumes adequate levels of nutrition. Thus, if the baby was born weighing 7 pounds, to stimulate the weight this baby would have at 2.5, we should multiply 7 by 4. So 7 multiplied by 4 equals 28 pounds, so we can conclude that at 2.5 years old the baby will weigh 28 pounds.
