The given question says that a student has constructed a model of cellular transport using fences and several gates.
This model can be used to demonstrate the cellular transport.
The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.
Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.
Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.
The roots of eh gymnosperms are long and deep, with the advantage to gather deep water. Thus, option D is correct.
Roots are the important network of tissues that gathers the water and essential nutrients from the soil and allow growth.
<h3>What type of roots are in Gymnosperms?</h3>
The gymnosperms are advanced plants with bare seeds. The roots system in the gymnosperms is the taproot system.
The root system in the gymnosperm is the long deep roots that are immersed deep inside the soil.
Thus, the advantage of roots to gymnosperms arises from the deep root for gathering water below the surface. Thus, option D is correct.

Answer:
Overconsumption of resources, that makes the most sense to me. Hope this helps!
Answer:
True
Explanation:
Bacteria generate toxins which can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. Usually, an endotoxin is part of the bacterial outer membrane, and it is not released until the bacterium is killed by the immune system.Most viral infections eventually result in the death of the host cell. The causes of death include cell lysis, alterations to the cell's surface membrane and various modes of programmed cell death. Some viruses cause no apparent changes to the infected cell.
