Answer:
a. hemoglobin now binds more oxygen at low partial pressures than at high partial pressures.
Explanation:
I took regular Biology in 9th Grade, AP Chemistry in 10th Grade, AP Biology in 11th Grade, and DE (Dual Enrollment) Microbiology in 12th Grade. Currently majoring in Biology at the University of Michigan - Ann Arbor.
Answer:
Yes the cell will re-aggregate
Explanation:
Cells from tissue B are isolated and dissociated, then treated with the antibodies raised against cell type A membrane proteins. Will cells from tissue By aggregate.
Aggregation permits a cell-cell contact present in a tissue, this enhances the function and behavior if the cells.
Answer:
Frogs do have gills as well as fully developed lungs which help them to survive both on land and underwater. On the other hand, tadpoles have chubby bodies, long tails and they do not look like a frog eventually in which they turn into. Their lungs take time to develop but once developed they too can live on land.
Explanation:
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.
The fossil record shows that life found on earth before was much different from life found on earth today.
