In the nephron, approximately 20 percent of the blood gets filtered under pressure through the walls of the glomerular capillaries and Bowman's capsule. The filtrate is composed of water, ions (sodium, potassium, chloride), glucose and small proteins (less than 30,000 daltons -- a dalton is a unit of molecular weight). The rate of filtration is approximately 125 ml/min or 45 gallons (180 liters) each day. Considering that you have 7 to 8 liters of blood in your body, this means that your entire blood volume gets filtered approximately 20 to 25 times each day! Also, the amount of any substance that gets filtered is the product of the concentration of that substance in the blood and the rate of filtration. So the higher the concentration, the greater the amount filtered or the greater the filtration rate, the more substance gets filtered.
This filtration process is much like the making of espresso or cappuccino. In a cappuccino machine, water is forced under pressure through a fine sieve containing ground coffee; the filtrate is the brewed coffee. The arrangement of the glomerular capillaries in series with the peritubular capillaries is important to maintain a constant pressure in the glomerular capillaries, and thus a constant rate of filtration, despite momentary fluctuations in blood pressure. Once the filtrate has entered the Bowman's capsule, it flows through the lumen of the nephron into the proximal tubule.
That they can no longer breed together to reproduce fertile offspring.
Answer:
If the pH of the water was too high or low, if the temperature was too hot or cold, or even the climate in which is provided to them inside of the tank can abiotically effect the population of the tank.
Explanation:
This is because of their natural abilities and capabilities. For reference: Many people like different temperatures whether they want to or not its a preference and if they were to change their location in which it has a new climate it would effect the way that they do things. Such as, a change in clothing.. But fish do not have clothes. Therefore it is unfortunate that some of their population does die naturally even in the wild do to this.
Answer:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. ... It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
Explanation:
Mitochondrial DNA (mtDNA) typing is used in forensic science for it serves as an important tool in determining the recovered damaged, degraded or small sample source of the DNA. Mitochondrial DNA is a small genome that is found in the mitochondria, just outside of the nucleus of the cell.
