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.

Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. de
Pie

Answer:

Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.

Explanation:

Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.

A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli.  This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.

Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)

If the  alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.

If the  alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.

pickupchik [31]

Answer:

Biological membranes consist of a double sheet (known as a bilayer) of lipid molecules. This structure is generally referred to as the phospholipid bilayer. In addition to the various types of lipids that occur in biological membranes, membrane proteins and sugars are also key components of the structure.

Guys I need help!! with biology 1 I don’t understand what the independent and dependent is nor the what causes or what changes!
frozen [14]

Answer:

5) air temperature - corn sprouting time

6) sacks of fertilizer sold - algae growth

7) cars - pollution levels (sorry couldn't read the full problem, but you get it)

8) distance of flash light - size of illuminated area

9) number of answered questions - score of the final

10) minutes of exposure - birth defect rate

11) amount of vitamin A - weight fluctuation

12) fox population - rabbit population

Explanation:

So as the words speak for themselves, dependent variables are variables that aren't changed by outside factors unlike dependent variables which change based on an outside change. Knowing this, if you reread the problems you will be able to understand it a little bit more.
