11. In which of the following examples will water move into the cells of the large intestine from the outside environment by the process of osmosis?
Osmosis occurs in the large intestine to transfer water from the feces into the neighboring cells.
What is the process of osmosis?Water is transported across cell membranes through diffusion and osmosis. The body reabsorbs absorbable solutes and electrolytes from meals (namely salt, potassium, and chloride ions).
The total solute concentrations and the permeabilities of the solutes in relation to water define the effective osmolality of a biological fluid, the large intestine to transfer water from the feces into the neighboring cells.
Water molecules move by osmosis across the cell membrane from a lower solute concentration to a higher solute concentration.
Therefore, osmosis, a kind of diffusion, is how water enters and exits the cell's large intestine to transfer water from the feces.

A. A
B. B
C. C
D. C
The correct answer is A
Explanation:
Cancer including cancerous mass or tumors is caused by an abnormal and uncontrolled reproduction of cells. This means cell division occurs faster than normal and leads to damaged or malfunctioning cells. Moreover, in terms of the number of cells vs time, cancer leads to a high number of cells in a short time. This occurs in cell A because different from cells B, C, and D, this has increased the number of cells in a short time, while others have decreased over time or remain constant. According to this, the cell that is a cancerous mass is A.

What is Tissue Culture?
Tissue culture is the process of growth of tissues or cells in an artificial medium that is separate from the parent organism. This technique is also known as micropropagation method. It is typically facilitated via the use of a liquid, a semi-solid, or a solid growth medium, such as the broth or agar medium.
Tissue culture is used widely in science for the propagation of plants, in the study of medicines such as those related to cancer. Tissue culture can be used as a treatment option in cancer as this technique does not show any harmful or ineffective medication. The cultured tissues of stem cells can be used for replacement of infected cells or body parts.
Therefore, the correct option is A.

Hydroponics is defined as the practice of growing plants without soil used to provide support or nutrients or ‘Soilless Farming'. How is ‘Hydroponics' an effective method of farming in arid and dry zones other Earth?
Answer:
Hydroponics solves the problem of unavailability of water in those arid and dry regions
Explanation:
As rightly stated in the question, hydroponics is a practice that involves the culturing of plants without the need for soil. Hydroponics procedure make use of a moisture-containing solution filled with nutrients.
This procedure of hydroponics, however, comes with some disadvantages but one major effectiveness it has in arid or dry regions is that it SOLVES THE PROBLEM OF WATER UNAVAILABILITY. When it comes to farming practice using soil, constant water supply is an unnegotiable criterion because water is needed for the growth of plants in the soil.
However, in arid regions, which are usually very dry due to lack of rainfall, the practice of hydroponics can substitute for soil farming in order not to cause food scarcity.
