Answer:

An example of human-caused disturbance is the forest clearing. Explanation:

Forest clearing means removing the trees of land for more area which can be used for anything other than a plantation of forest purpose. It is the human-caused disturbance in the environment which is harming our nature.

Due to the increase in population, there is a need for more work and residential needs these all things contribute together for deforestation. Deforestation is the cause of global warming. Forest clearing is causing a disturbance in atmospheric pressure too.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
