Answer:
Diffusion is the net movement of any substance from a higher concentration region to the lower concentration region. It is conducting by a concentration gradient.
Osmosis is a process in which solvent (molecules) pass through a semipermeable membrane (SPM) from a lower concentration solution region to a higher concentration region so it equalizes the concentrations on each side of the SPM.
A <u>hypotonic solution</u> is a solution that has a higher concentration of solutes inside the cell than outside of the cell. Thus the movement of water is from outside to the inside of the cell.
A <u>hypertonic solution</u> is a solution in which solutes concentration is greater outside the cell and low concentration inside. The movement of water is from inside the cell to outside the cell.
An <u>isotonic solution</u> where two solutions having the same concentration inside and outside of the cell so there is free movement of molecules across a semipermeable membrane.
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.
Neisseria gonorrhoeae is treated with a combination of drugs because the organism is resistant to many, including penicillin and fluoroquinolones.
Gonorrhoeae is a contender to produce an incurable illness due to the development or acquisition of resistance mechanisms for sulfonamides, penicillins, tetracyclines, ciprofloxacin, and more recently azithromycin and ceftriaxone during the past 80 years.
The Neisseria gonorrhoeae bacteria is the source of the sexually transmitted illness (STD) known as gonorrhea. The urethra in both men and women as well as the cervix, uterus, and fallopian tubes in women are all affected by N. gonorrhoeae infection.
Penicillin is the first drug that has been shown to be effective against syphilis and gonorrhea. However, compared to the dosage required to treat syphilis, which is often approximately 1,000,000 units, the drug used to treat gonorrhea is frequently administered in doses of just around 100,000 units.
