Answer:
Hemodialysis is the extracorporeal cleansing of wastes from the blood.
Explanation:
Hemodialysis is the process of kidney dialysis. This process is used for the purification of blood. Extracorporeal blood purification includes removal of waste product such as urea , water and toxic elements from patients body. This process is used when patient's kidney is not working properly.
Answer:
Swim bladder
Explanation:
Swim bladder is an organ in bony fishes such as catfish that controls their buoyancy. It is also known as air bladder. The swim bladder contains gas, mainly oxygen and functions as a hydrostatic organ.
As the fish moves in deeper water, the gas in the swim bladder is contracted which decreases the volume of swim bladder.
The answer is 5. Meiosis I reduces the ploidy of a cell by half.Therefore, if a cell was diploid (2n), then at the end of meiosis I, the two formed daughter cells will have haploid (n) number of chromosomes. Meiosis II is similar to mitosis and does not reduce ploidy.
(2n)/2= 10/2; n = 5
Answer:
germiline and somatic
Explanation:
Germline mutations occur in gametes. These mutations are especially significant because they can be transmitted to offspring and every cell in the offspring will have the mutation.
Somatic mutations occur in other cells of the body.
Answer:
The urinary system or the Renal systems regulates or takes out waste from the blood, maintain blood pressure, and controls the ion exchange process.
The parts of urinary system includes:
- Kidneys
- Ureters
- Bladder
- Urethera
Formation of urine :
When the blood passes through the kidney, it filters the blood. This is a 3 step process:
1) Glomerus filtration: This is the place where formation of urine starts. In glomerus, the water and solute from tiny capillaries and enter the capsule of the glomerus.
2) The tubular re-absorption: Most of the water and solute gets reabsorbed through this part
3) Tubular secretion: Extracellular fluid molecules get transferred into the nephron, these secretions get discarded out of the body containing mainly creatinine, urea, uric acid, K+ and H+ ions
NEPHRON :
The simplest unit of kidney and its the basic unit that filter the blood. One kidney has approximately 1. 5 million nephrons!
