Answer:
b. the positive feedback's effector responses are in the same direction as the initiating stimulus rather than opposite of it
Explanation:
Both positive and negative feedback have the same components:
1. Stimuli - external or internal
2. Sensors - detect the stimuli
3. Control center - processes the information (CNS)
4. Effectors - activated by control center
Negative feedback loops act to oppose the stimulus.
Unlike negative feedback loops, positive feedback loops amplify the starting signal.
Mechanical stress occurs in the form of weight bearing movement and exercise, and it is required for normal bone remodeling. Stress is detected by osteocytes and communicated to osteoblast. These cells then increase synthesis of esteoid, and this is followed by deposition of mineral salts. Bone strength increases over a period of time in response to mechanical stress.

Answer:
Asexual reproduction can be described as a method of reproduction in which only one parent is involved. The offsprings produced as a result of asexual reproduction are identical to their parent. Hence, limited evolution occurs in these organisms over a period of time. A bacterial cell reproduces by binary fission. In such kind of asexual reproduction, the parent cell splits into two daughter cells which are similar to the parent cell.
Sexual reproduction can be described as a method of reproduction in which two parents are involved. The offsprings are not usually similar to the parents due to the recombination. Sexual reproduction occurs by the process of meiosis. The recombinations that occur in such kind of reproduction brings variations among species.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP<span>. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water</span>
