The bicarbonate buffering system in the blood is the most important buffering system in the ECF. Bicarbonate ion and carbonic acid are the key components of this buffering system. The weak base <u>bicarbonate</u> serves to buffer the strong acid <u>H+</u><u>.</u> The buffer to the strong base <u>OH-</u><u> </u>is <u>carbonic acid</u>. The byproduct of these reactions is <u>water.</u>
Explanation:
A buffer system utilizes chemical buffers and resists any changes in the pH and adjusts acidity and alkalinity of the medium by binding or releasing H+ ions accordingly.
A bicarbonate buffering system in the ECF regulates the bicarbonate level and maintains the normal acidity level of blood.
Sodium bicarbonate reacting with a strong acid (HCl) produces a weak acid (carbonic acid) and sodium chloride. A strong base like (NaOH) reacts with carbonic acid producing bicarbonate and water.
NaHCo3 + HCl → H2CO3 + NaCl
H2Co3 + NaOH → HCO3 + H20
The acidity of the blood is regulated by maintaining the ratio of bicarbonate and carbonic acid at 20:1 under normal conditions through the bicarbonate buffer system. The carbonic acid level is regulated by the respiratory system; while carbonate level is regulated by the renal system.
Answer:
Both organisms are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane. The biggest difference between prokaryotes and eukaryotes is that eukaryotes have a nucleus. They also have other membrane structures called organelles
Answer:
The correct answer is option - d. Production of primary spermatocytes.
Explanation:
The accessory cells or supporting cells present within the seminiferous tubules of reproductive system termed as the Sertoli cells. They play various roles in the body and reproductive system.
Sertoli cells make blood-testis barrier in adjacent Sertoli cells in the seminiferous tubules. These cells secrete different types of enzymes and hormones such as inhibin which are also secreted by ovary and placenta in females. Sertoli cells produce seminiferous tubular fluid to provide nutrition to the sperm. Apoptotic germ cells are timely eliminated by these cells.
Thus, the correct answer is option D. Production of primary spermatocytes.
Answer:
swell
Explanation:
the cell will swell and become turgid as more water will be absorbed into said cell. this process is called osmosis, where water passes through a partially permeable membrane.
It is killing of population forcing us to self quarantine and stay away from people. Quarantine is marking many people depressed because we can’t talk or visit people face to face and it’s harming many people with anxiety and depression it’s making them worse.
