Explanation:
<em>The advice I would give to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.</em>
If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.
If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.
Answer:
Incorrect
Explanation:
In the bone modelling process, osteoblasts a responsible for bone formation and osteoclasts are responsible for bone resorption. In the young adult during growth, the formation of bone exceeds the resorption of bone to maintain bone mass. Therefore,
As we get older, bone formation decreases due to reduction in osteoblastic activity and numbers and bone resorption increases as a result of sex hormone deprivation, this will result in decreased bone mass (osteoporosis). Therefore, osteoclastic activity would have to exceed osteoblastic activity in order or osteoporosis to develop
