The best scientific theories not only explain and organize known facts but also generate new predictions
Answer:
Palpation of the prostate is done by palpating it through the anterior portion of the rectal wall.
Explanation:
Prostate palpation is performed in doctors' offices during a routine urologist appointment. The specialist will ask the patient to take off his clothes and lie on a stretcher. The position for rectal touch depends on the practice of each doctor. It can be done lying in bed in the gynecological position, lying on its side or standing flexing the abdomen on the stretcher.
The doctor will introduce the gloved, lubricated finger into the rectal region (canal that connects the anus to the rectum) and reach the prostate through the anterior portion of the rectal wall. The exam takes approximately 10 seconds to complete. The procedure is painless, but may end up causing some discomfort.
Answer:
a. are quick to adapt to a particular stimulus intensity.
Explanation:
Phasic receptors are the one that first generates an action potential in response to the stimulus. However, they adapt to that intensity of the first stimulus and reduce signaling. Slowly, they even stop signaling irrespective of the presence of stimulus of the same intensity.
This is the reason that we get adapted to the specific odor such as gas leakage after some time even if the leakage continues.
Speciation is the formation of a new species from an existing species and can occur in two phases. Those two phases are change of an existing species, and splitting of an existing species into two or more different species. An example of speciation would be the Galapagos finch - there are different kinds of this species all over the Galapagos archipelago.
