The answer is true cause the movement of water and small particles through a membrane due to hydrostatic pressure, from high pressure to low pressure.
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.
They use a formula and that formula is
People/Land Area=Population Density
Its B clearing and farming. Because if you think of it when someone clears trees and bushes they most likely won't come back.
The correct answer is FALSE.
It is false that the only factions which disagree with each other is economists and environmentalists.
Economists are referred to as practitioners which are found in the social science and their work is to discipline economics.
A person can develop, study and apply some concepts and theories from economic.
Environmentalists are termed as supporters who supports the movement of the environment.
There is a ethical movement of the movement or political which works to protect and improve quality of environment which is natural.
Environmentalist believes in environmentalism philosophy.
