Through osmosis, water can freely pass the membrane from the most diluted side to the less diluted one. Option a. swell

Osmosis is the simple passive transport of water molecules that occurs when two dilutions of different concentrations -in this example, the interior of the cell and the beaker content- are separated by a semipermeable membrane.

The membrane allows the pass of water but not solute (glucose). Hence, water can move from the most diluted side to the less diluted one. In other words, water moves from the less concentrated side to the more concentrated side (conserning the solute).

According to this information, the interior of the cell is more concentrated and less diluted than its exterior. Hence, water will move from the extracellular space foward to the cell interior, and the cell will swell.

Option a. swell

Answer:

25%

Explanation:

According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.

This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:

30/120 × 100

= 1/4 × 100

= 100/4

= 25% of the selected seeds are infertile.

Ampulla controls the movement of tube feet.

Tube feet are small active tubular projections on the oral face of an echinoderm, whether the arms of a starfish, or the undersides of sea urchins, sand dollars and sea cucumbers; they are more discreet though present on brittle stars, and have only a feeding function in feather stars.

Tube feet function in locomotion, feeding, and respiration. The tube feet in a starfish are arranged in grooves along the arms. They operate through hydraulic pressure. They are used to pass food to the oral mouth at the center, and can attach to surfaces.

In some species, the tube feet are specialized to form respiratory tube feet that are thin-walled and are extremely flattened to provide a larger surface area for the absorption and exchange of gaseous substances.

When potato pieces are placed in more concentrated sucrose solutions, their uptake of water decreases. Plant and animal cells respond differently in hypertonic, isotonic, and hypotonic solutions, with plant cells undergoing plasmolysis and animal cells undergoing crenation or lysis.

Yes, more dilute concentrations of sucrose can affect the amount of water taken up by potato pieces, as factors other than solute concentration come into play. Specifically, the volume and composition of the pieces can impact the uptake of water. When potato pieces are placed in sucrose solutions of increasing concentration, the amount of water taken up by the pieces decreases after incubation.

To estimate the osmolarity of potato tuber tissue, a graph of percent weight change of potato cores against the molarity of the sucrose solution they were placed in should be plotted. By extrapolating the line of best fit on the graph, we can identify the point where there is no net gain or loss of water by the potato core, indicated by a percent weight change of zero. At this point, the molarity of the solution would be equal to the osmolarity of the potato tuber tissue.

In this experiment, four solutions were used: distilled water, 0.2 M sucrose solution, 0.4 M sucrose solution, and 0.6 M sucrose solution. To determine the water potential of the potato tuber tissue at room temperature, the following four solutions were chosen: 0.0 M, 0.2 M, 0.4 M, and 0.6 M sucrose solutions. The students can then use the equation Ψ = -iCRT to calculate the water potential, where Ψ represents water potential, i is the ionization constant (assumed to be 1.0), C is the molar concentration of sucrose, R is the pressure constant (0.0831 liter bars/mole K), and T is the absolute temperature in Kelvin (273 + °C).

It is important to note that plant and animal cells respond differently when placed in hypertonic, isotonic, and hypotonic solutions. When exposed to a hypertonic solution, plant cells lose water and undergo plasmolysis, causing the protoplast to shrink away from the cell wall. In contrast, animal cells undergo crenation, which is the shrinking of the cell due to water loss. In an isotonic solution, both plant and animal cells reach equilibrium, with no net gain or loss of water. When placed in a hypotonic solution, plant cells gain water, causing the protoplast to expand and press against the cell wall, resulting in a turgid cell. Animal cells swell and may undergo lysis, where the cell bursts due to excessive water uptake.

In the given context, the solution in the beaker was hypertonic, as it had a higher solute concentration compared to the potato pieces. The dialysis bag contained albumin, but it was not present in the beaker. Conversely, fructose was present in the beaker but absent in the dialysis bag. It is worth noting that the dialysis bag decreased in volume.

The three layers of the ureter's wall are the inner mucosa layer, the middle muscular layer, and the outer Adventitia layer. Muscular waves help propel urine through the ureters to the urinary bladder, where it passes through a flaplike valve in the mucous membrane.

Inner Mucosa: The innermost layer is the mucosa, which is composed of transitional epithelium. This layer lines the inside of the ureter and helps prevent urine from leaking back into the kidneys.

Middle Muscular Layer: The middle layer is the muscular layer, consisting of smooth muscle fibers. These muscles contract in wave-like motions (peristalsis) to propel urine from the kidneys to the urinary bladder.

Outer Adventitia: The outermost layer is the adventitia, which is a fibrous connective tissue layer. It provides structural support and protection to the ureter.

As urine reaches the urinary bladder, it passes through a flap-like valve called the ureterovesical valve, which is located in the mucous membrane of the bladder. This valve prevents urine from flowing back up into the ureters and kidneys.

Urine: Normal urine consists of 95% water and 5% dissolved substances, including urea, uric acid, various electrolytes (like sodium, potassium, and chloride), and small amounts of glucose and amino acids.
Ureter: The ureters are muscular tubes extending from the kidneys to the base of the urinary bladder.

Answer:

The correct order of protein production is:

c) 1,2,4,3

Ribosome: Protein synthesis begins in the ribosomes, which are located either in the cytoplasm or attached to the endoplasmic reticulum.

Endoplasmic Reticulum: After the initial stages of protein synthesis in the ribosomes, the newly synthesized protein is transported into the endoplasmic reticulum (ER) for further processing and modification.

Golgi Apparatus: The proteins synthesized in the ER undergo further processing and modifications in the Golgi apparatus. This includes sorting, packaging, and modifying the proteins to their final functional forms.

Secretory Vesicles: Once the proteins are properly processed and modified in the Golgi apparatus, they are packaged into secretory vesicles. These vesicles transport the proteins to their destination, such as the plasma membrane for secretion outside the cell.

Therefore, the correct order is 1, 2, 4, 3.

Answer:

The correct order of protein production is ribosome, endoplasmic reticulum, Golgi apparatus, and secretory vesicles. So the correct answer would be c) 1,2,4,3.

Many proteins destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are synthesized on ribosomes that are bound to the membrane of the endoplasmic reticulum. The Golgi apparatus then distributes these proteins and lipids that it receives from the ER.
