The decline in bone breakdown and increased mineralization causes blood calcium to decrease <span>back to normal levels. This happens when there is secretion of calcitonin. This circulation calcitonin is inhibiting </span>osteoclasts<span> and it will stimulate osteoblasts within minutes. The effect of this on osteoclast will cause a decrease in reabsorption and a concurrent increase in deposition because of the osteoblasts activity.</span>
Answer:
c. is inactivated by binding lactose
Explanation:
Lactose is a sugar mostly present in milk or dairy products. It is degraded in the body by an enzyme called LACTASE. Since lactase is an enzyme (protein), it must be encoded by a structural gene (Lac gene). However, the expression of this structural gene can be inhibited by the absence of lactose.
Ideally, when lactose is present, it binds to a DNA binding protein called Lac repressor protein (inhibitor) causing the inhibitor protein to lose its shape and fall off, allowing transcription of the lac gene to occur. In other words, the presence of lactose deactivates the inhibitory function of lactose repressor protein.
Population is a specific species and community is more so talking about all of the species as a whole in an environment.
Answer:How are species related to the concept of biodiversity? Species are diverse because there are so many and they are all different. Each species is biologically diverse from another. Biodiversity leads to adaptations and natural selection.
