A student performs an experiment to study the transport of water in and out of cells. He uses clear, semi-permeable plastic bags to represent the cell membrane. The student places three plastic bags of the same size, each containing a 1% concentration sucrose solution, into three different beakers. One beaker contains distilled water, another beaker contains a 3% concentration sucrose solution, and the third beaker contains a 1% concentratIon sucrose solution. The diagram shows the students experimental setup, the plastic bag before it is placed in the beakers, and the appearance of the bags after an hour in each solution. Which statement provides a conclusion about the transport of water in and out of cells based on the results of the students experiment?

Answers

Answer 1

Answer:

B

Explanation:

A. Water moves freely both inside and outside the cell independent of the solute concentration.

B. Water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell.

C. Water transports solutes out of the cell to balance the percent concentration of solutes both inside and outside the cell.

D. Water moves into the cell solutes move out of the cell to ensure their concentration is balanced both inside and outside the cell.

The correct statement that provides a conclusion about the transport of water in and out of the cells is that water movement into the cell is dependent on the percent concentration of solutes both inside and outside the cell.

Water molecules will always move from the region of higher water potential to the region of lower water potential. The more the solute concentration of a solution, the lower the water potential compared to a solution with a lower solute concentration.  

Hence, water will move from the beaker containing distilled water into the plastic bag containing a 1% sucrose solution until an equilibrium is established - the solution in the beaker is hypotonic to the one in the bag.

On the contrary, water will move from the bag containing 1% sucrose solution into the beaker containing 3% sucrose solution until there is no longer any net movement of water - the solution in the beaker is hypertonic to the one in the bag.

There will not be any movement of water from the bag to the beaker containing 1% sucrose because both solutions are of the same concentration, that is, isotonic.

The correct option is B

La Fase más larga del Ciclo Celular es_____________________ y en ella ocurre____________________________________________________ _______________________________________________________________________________________________________________________________

Answers

Answer:

La fase más larga del ciclo celular es la interfase  y en ella ocurre una gran producción de proteínas.

Explanation:

La célula pasa el 90% del tiempo del ciclo celular en la interfase, lo que significa que esta es la fase más larga del ciclo celular.

La interfase ocurre entre dos divisiones celulares consecutivas y es el período en el que la célula no se divide, sino que se prepara para ello, produciendo tantas proteínas como sea posible, que serán utilizadas en la división. Esta fase es tan grande que se divide en tres etapas llamadas G1, S y G2.

ATP provides energy needed to carry out many cellular functions. Which of the following processes does NOT require ATP? A. active transport of a protein across a membrane B. making more ATP C. passive transport of oxygen across a cell membrane D. muscle contractions

Answers

C. Passive Transport

ATP provides energy needed to carry out many cellular functions. Passive transport of oxygen across a cell membrane is does not require ATP. Hence option C is correct.

What is cellular function?

Cellular function is defined as protein synthesis, translocation of molecules across the cell membrane, and cell division to create new cells. They provide the body with structure, take in food's nutrients, convert them into energy, and carry out certain functions.  Additionally, cells have the ability to replicate themselves and contain the body's genetic material.

In primary active transport, molecules are moved across a membrane against their gradient directly using a chemical energy source (such as ATP). Ion transport, muscular contraction, nerve impulse transmission, substrate phosphorylation, and chemical synthesis are just a few of the processes that use ATP as an energy source. By adding a phosphate group to another molecule, ATP can drive biological operations.

Thus, ATP provides energy needed to carry out many cellular functions. Passive transport of oxygen across a cell membrane is does not require ATP. Hence option C is correct.

What happens to the amount of light as the moon travels from the new moon phase to the full moon phase?​

Answers

Explanation:

Between the new and full Moon, the amount of Moon we see grows — or waxes from its right side toward its left side. As it passes the full Moon stage, the amount of illumination decreases — or wanes — from right to left. ... No matter where on Earth an observer is, however, the phases of the Moon occur at the same time.

[tex]\huge\bold\pink{Answer:-}[/tex]

Moon phases represent the names given to points in its orbit around Earth. Each phase lasts for only an instant as the moon constantly moves. To the naked eye, the full moon lasts about three days, but in reality, it is a full moon for just an instant before it begins to wane. The moon takes just under one month -- an average of 29 1/2 days -- to complete its phases.

Phases of the Moon:-

The moon has eight phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter and waning crescent. But it is not as simple as dividing 29 1/2 by eight to find out how long each phase lasts. The fraction by which the moon is illuminated steadily increases or decreases at all times.
