15. Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 30 percent solute solu
Vaselesa [24]

Answer:

Smaller

Explanation:

The human blood cell has a smaller percentage of solute concentration than the solution it was placed into. This means that the cell is hypotonic in comparison to the solution, and the solution is hypertonic compared to the cell. When a cell is placed in a hypertonic solution it undergoes crenation, meaning it shrivels up. Water moves from the lower solute concentration to the higher solute concentration. The water inside the cell moves outside to the hypertonic solution. This causes the cell to become smaller.

The portion of the tubule system that is relatively impermeable to solutes but contains many aquaporins for water reabsorption
topjm [15]

Descending limb of loop of Henle

It helps to maintain the concentration of urine. It is highly permeable to water thus water is readily reabsorbed from the descending limb by osmosis. It is impermeable to sodium and chloride ions.

<h3>What is a Tubule system ?</h3>

The transverse tubular system is a network of interconnecting rings, each of which surrounds a myofibril

  • The nephron uses four mechanisms to convert blood into urine: filtration, reabsorption, secretion, and excretion. These apply to numerous substances

  • The distal convoluted tubule (DCT) and collecting duct (CD) are the final two segments of the kidney nephron. They have an important role in the absorption of many ions, and in water reabsorption.

Place the 4 steps of biofilm formation, listed below, in the correct order.
makvit [3.9K]

Answer:

1. Surface (substratum) is preconditioned by environment molecules.

4. Microbes attach and detach from the preconditioned surface.

2.Quorum sensing and the establishment of the extracellular matrix commences as microbes attach more stably.

3. Biofilm matures and some microorganisms escape to the plank-tonic state.

Explanation:

Biofilm is a process in which microorganism irreversibly attach and grow on the surface to produce extra cellular polymers that facilitate formation of matrix. The biofilm process takes three days for the formation after which thickness of plaque increases. There are 4 main steps in biofilm formation. Surface is preconditioned by environment molecules. The microbes attach the preconditioned surface. Establishment of extra cellular matrix and finally biofilm matures.
