According to BBC, Human activities such as harvesting plants and hunting animals can unbalance the flows and cycles within those [SMALL SCALE ECOSYSTEMS ]ecosystems. Tree-felling may lead to soil erosion and a loss of habitat. Lack of shade and moisture in the soil can result in desertification.

According to National Geographic, Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

Cell wall. The plant cell wall accounts for the turgidity and the rigidity in plants. The cell wall protects the plant cell from bursting due to the influx of water. Rather than bursting, the cell is able to withstand the osmotic pressure exerted by the water molecules.

Kidneys are externally surrounded by a three-layer capsule, and internally composed of the cortex, medulla, and pelvis. In the image, 1) Cortex, 2) Medulla, 3) Sinuses , 4) Capsule.

The kidneys are bean-shaped, bilateral urinary organs located at each side of the vertebral column, under the ribs, and behind the abdomen (superior right and left abdominal quadrants).

Their main function is to filtrate blood, eliminate wastes and water excess through urine, and keep internal homeostasis.

When blood enters the kidneys, water, salts, and other waste substances are eliminated as urine, and the filtrated blood returns to the organism.

Kidneys are composed of different parts.

Externally,

Internally,

The medulla is arranged as pyramidal masses composed of tubular structures. In between the pyramids, there are renal papilla and calyces.

A red onion cell placed in a saline solution will lose water when water moves from the cell to the surrounding hypertonic medium via osmosis, causing the cell to shrivel up.

The passage of solvent molecules from a lower concentration solution to a higher concentration solution across a semipermeable membrane. It is a passive process that occurs without the use of any energy.

Solvent molecule transfer proceeds from low to high concentration regions until the concentrations on both sides of the membrane are equal.

Thus, we can conclude that when a red onion cell is placed in salt water.

As we can see in the diagram the onion cell shrink which means it is placed in salt water which is a hypertonic solution.

So, option (3) salt water is correct.

Explanation:

Given what we know about the biological mechanisms behind anaerobic exercise, we can confirm that the production of lactate ensures a continuous supply of NAD.

In order for us to undergo any physical exercise, it is imperative that we are able to produce energy within our cells. The energy used by cells is in the form of a molecule by the name of ATP, which is produced primarily through a process known as Glycolysis.

This is relevant given that in order for glycolysis to happen, a key protein is required known as NAD+. Lactate is produced from pyruvate only under anaerobic conditions because these are conditions that lack oxygen which is the only other source of NAD+, therefore, pyruvate must be converted to lactic acid to make it possible to continue glycolysis and the production of ATP.
