I think the best answer for the question your asking is A; the reason why is because with constricted blood vessels and increased blood volume that's your best way to have increased blood pressure.
They determine it because of the hypothesis. It changes during the investigation and the independent variable stays the same through the whole experiment.
Robert Hooke was the First scientist to used the term cell
<u>Explanation</u>:
Robert Hooke first discovered and named it as cell in 1665. He discovered it in a dead cell wall of plants, through a primitive microscope. Later he also, described the structure of cell as small rooms or cellular in which monks used to live. These description can be found in a book called micrographia. The cell which Hooke observed does not show any presence of nucleus in the cell and other organelles that are generally seen in other living cells.
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!
