Which age related change can cause nocturia? decreased ability to concentrate urine decreased production of antidiuretic hormone
pogonyaev
Nocturia, or nocturnal polyuria, is a medical term which means excessive urination at night. The two primary causes of nocturia are hormone imbalance and vesicle problems. Arginine vasopressin (AVP) and atrial natriuretic hormone (ANH) are two of the hormones that controls the body water level. AVP is an antidiuretic hormone produced by hypothalamus while ANH is released by cardiac muscle cells in response to high blood pressure. Arginine vasopressin (AVP) is an antidiuretic hormone which increases water absorption in the collecting duct systems of of kidney nephrons subsequently decreasing urine production. In the abovementioned question, nocturia is caused by decreased production of antidiuretic hormone, which is the arginine vasopressin. Nocturia, moreover, is can be caused by congestive heart disease, nephritic syndrome or liver failure. Excessive nighttime drinking and obstructive apnea can also lead to nocturia

Answer:

Answer is B.

nitrogen (78.10%), oxygen (20.90%) - this combination of gases dominate the Earth’s atmosphere.

Explanation:

The atmosphere of earth is a gaseous layer which surrounds the earth. It  protects the life on earth by absorbing harmful ultraviolet radiation, reducing temperature extremes, maintaining the existence of  liquid water on the earth's surface and warming the surface. The atmosphere consists of many gases including some pollutants and greenhouse gases. Nitrogen is the gas present in the atmosphere most abundantly while Oxygen and Argon take the second and third place. Atmosphere contains approximately 78% of nitrogen , 21% of oxygen and 0.9% of argon. Gases like carbon dioxide, nitrous oxides, methane, ozone and the water vapor constitutes the rest of the atmosphere. Many small particles called aerosols are also there which include dust, spores, pollen, volcanic ash, smoke etc. There are five layers of atmosphere. Troposphere (0 to 12 km) where we live is the lowest layer of earth's atmosphere ,which is closest to the earth's surface contains half of the atmosphere. Here most clouds are found and almost all weather occurs. Stratosphere (12 to 50 km) is the second layer where jet aircraft and weather balloons fly. It contains the ozone layer that absorbs harmful radiation from the sun.  Mesosphere (50 to 80 km) is the third highest layer and the coldest part of the atmosphere where most meteors burn up upon entering in to the atmosphere. The fourth layer is thermosphere (80 to 700 km) where the International Space Station orbits earth and the space shuttles flew. Exosphere (700 to 10,000 km) is the outermost layer where the atmosphere merges into outer space. Most of the satellites orbiting earth are found here.

You mix activated yeast with different carbohydrates and measure the CO2 production over a time span of 10 minutes for each type
LenaWriter [7]

Answer:

quantitative analysis

Explanation:

Qualitative analysis refers to quality whereas quatitative analysis refers to the amount or quantity. In this experiment, we see how much carbondioxide gas is produced after the use of different carbohydrates given to the yeast. In this experiment, we want to know the concentration of the product in the reaction not the quality so we can say that this experiment shows quantitative analysis as compared to qualitative analysis.
