Answer:
That is true.
Explanation:
Osteoporosis promotes bone loss and people who suffer from this disease are more prone to fractures, especially in dangerous places like the hips and spine. Although some factors that promote this disease cannot be avoided, such as the genetic factor, osteoporosis can be prevented and even avoided with adequate intake of calcium, which is one of the main elements of bone mass. However, it is incorrect to say that only calcium intake is sufficient to prevent osteoporosis, as it is necessary to combine food with constant physical activity, which is capable of strengthening and promoting density to the bones.

Answer:
The answer to fill in the blank in this question: Some hormones act through cell membrane receptors that stimulate adenylate cyclase activity and production of:____, would be: cAMP.
Explanation:
In the process of hormonal regulation of cells there are two ways in which this can happen: direct activation of DNA inside a cell through steroid hormones, who do not need any kind of mediators to enter the cytoplasm of a cell and activate its genetic material, or indirect activation, which is the common way for non-steroidal hormones, such as epinephrine. In this second scenario a hormone will reach the cell and lock onto a receptor on the plasma membrane. The effect is that a G-protein, which is adjacent to the receptor, activates the second-messenger system, meaning that the activity the hormone came to initiate, will depend on these mediators. the G-protein will then activate adenylate cyclase, which in turn will activate ATP and transform it into cAMP. It is cyclic AMP (cAMP) which will finally relay the original message sent through the hormone, to the genetic material of the cell.
