The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucro

se. Side A is half-filled with a solution of 2 M sucrose and 1 M glucose. Side B is half-filled with 1 M sucrose and 2 M glucose. Initially, the liquid levels on both sides are equal.

Answer:

Intially the glucose concentration is levelled and then the liquid level in side A will rise.

Explanation:

  • Initially the liquid ob both sides are in isotonic condition.
  • The membrane is permeable to glucose so glucose will diffuse from higher concentration (2 M) to lower concentration (1 M) until the concentration become equal (1.5 M) on both sides.
  • Know, the Side A have 2 M sucrose and 1.5 M glucose and  side B have 1 M glucose and 1 M sucrose.
  • The side A will become hypertonic and side B will become hypotonic and water will start moving from side B to side A.

Describe the three types of white matter fibers.
Vlad [161]

Answer:

The white matter fibers are the main component of the brain. Three different types of white matter fiber are :

Commissural fibers:

This fiber is important for the connection of the corresponding left hemisphere and right hemisphere of the brain.

Projection fibers:

These fibers helps in the connection of the brain stem and the spinal cord with the cerebral cortex.

Association fibers:

These fibers are associated with the connection of the brain regions within the same hemisphere of the brain.

Chloride ions, Cl-, follow actively transported Na+ ions from the nephrons into the blood. Would you not expect the Cl- concentr
DerKrebs [107]

Answer:

Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.

Explanation:

Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure

When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.

In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.

Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.

The cerebral cortex plays a major role in all of the following except
kondor19780726 [428]

Explanation:

Explanation:

<em>Complete answer: </em>

<em>a. foot tapping rhythm </em>

<em>b. long-term memory </em>

<em>c. breath holding </em>

<em>d. circadian rhythm </em>

The cerebral cortex plays a major role in all of the following except d. circadian rhythm

The cerebrum is split into the left and right hemispheres, while the cerebral cortex makes up the outer layer of the brain and is comprised of gray matter. Gray matter is made up of unmyelinated neurons.

The cerebral cortex is described as having motor, sensory and association areas, and is involved in thought, memory, perception, awareness, and language. Overall, it is associated with voluntary movement, thus the circadian rhythm, involved in homeostasis and the autonomic nervous system, is unrelated to its function.
