Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.
The majority of carbon dioxide is transported as part of the bicarbonate system. Carbon dioxide diffuses into red blood cells. Inside, carbonic anhydrase converts carbon dioxide into carbonic acid (H2CO3), which is subsequently hydrolyzed into bicarbonate (HCO3−) and H+. The H+ ion binds to hemoglobin in red blood cells, and bicarbonate is transported out of the red blood cells in exchange for a chloride ion. This is called the chloride shift.
Bicarbonate leaves the red blood cells and enters the blood plasma. In the lungs, bicarbonate is transported back into the red blood cells in exchange for chloride. The H+ dissociates from hemoglobin and combines with bicarbonate to form carbonic acid with the help of carbonic anhydrase, which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs.
Answer:
The correct answer is option E (testosterone).
Explanation:
The interstitial cells or Leydig cells are the individual or group of cells present in loose connective tissues surrounding the seminiferous tubules.
They are usually active in the production of dominant sex hormones in males that is testosterone responsible for male secondary sexual characteristics.They produce hormones in the presence of luteinizing hormone (LH) and growth hormone released by the pituitary gland.
The high cholesterol content and crystals of Reinke make the leydig cells appear pale in color.
Thus, option E- testosterone is the correct answer.
That is true it can not happen
Answer:
Explanation:
you could do Water's Attraction to Other Polar Molecules.
Cohesion, otherwise known as water's attraction to other water molecules, is one of the big properties of water. Water's polarity lends it to be attracted to other water molecules. The hydrogen bonds in water hold other water molecules together. Due to water's cohesiveness:
Liquid water has surface tension. This allows for insects, such as Water Striders, to walk on water.
Water is a liquid at moderate temperatures, and not a gas.
Using an eye dropper and a coin, you can slowly keep adding water to the coin and you will see cohesion.
The water molecules will stick together and form a dome over the coin. Keep adding drops until the drop breaks and spills off of the coin. This is caused by gravity overcoming the force of cohesion.
