question 2 (5 points)
listen
which of the following stimuli would cause the liver to produce more glycogen?
a) going several hours without eating anything
b) going several hours without drinking anything
c) consuming a breakfast sandwich containing many carbohydrates
d) consuming a steak containing many proteins

Explanation:

For Question 1, osteoblasts are cells responsible for bone - building and play a key role in new bone tissue formation during fracture healing. Osteoporosis is a bone - weakening condition, osteoclasts break down bone, and osteocytes are mature bone cells with different functions.
For Question 2, when carbohydrates are consumed, blood glucose levels rise. The body responds by converting excess glucose into glycogen in the liver. Going without eating lowers blood glucose and stimulates glycogen breakdown, not production. Lack of drinking affects water balance, not glycogen production. Protein - rich foods do not directly cause increased glycogen production in the liver.

Answer:

Question 1: C. Osteoblasts
Question 2: C. Consuming a breakfast sandwich containing many carbohydrates
