Roger has been lifting weights seriously for years. His twin brother Steven does not exercise regularly. Which of the following statements would be a reasonable hypothesis to make regarding differences between their skeletons?a. stevens hydroxyapatite combination is less than roger'sb. roger's skeleton underdoes less osteolysis than steven'sc. roger's osteoblasts are more active than steven'sd. all of the listed responses are correct

a. stevens hydroxyapatite combination is less than roger's

b. roger's skeleton undergoes less osteolysis than steven's

c. roger's osteoblasts are more active than steven's

Explanation:

The hydroxyapatite combination includes the minerals of the apatite group like calcium apatite. As the exercise enhances the bone stability and prevents it's deformity thus the hydroxyapatite or mineral density is expected to be higher in Roger than Stevens.

The osteolysis is the pathological destruction of the bone tissues. As Roger does regular exercise he is expected to have achieved more immunity over Stevens. Thus Roger is prevented from oesteolysis.

The osteoblasts are the cells that secrete matrix for bone synthesis as the exercise is responsible for strengthening the bone the osteoblasts in person who do regular exercise are expected to be more active. Thus Roger's osteoblasts are more active then Steven's.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.

answerall of the above;
