Answer:
Primitive Earth where life emerged was subjected to extreme conditions
Explanation:
The origin of life is still an issue of intense debate today, although most researchers believe that life emerged from primitive organisms generated by the synthesis of organic compounds in early Earth. In line with this theory, it has been shown that membrane-forming compounds can be formed in extreme conditions (i.e., UV rays, extreme temperature, etc). It is believed that such conditions recreated in a laboratory were similar to the early Earth about 3,900 million years ago, thereby supporting the idea of the 'primordial soup theory' proposed by John Burdon Sanderson Haldane in 1929.

answer : Permeable Rock layers allow the flow of fluid like substances through them, While Impermeable rock layers do not allow the flow of fluid like substance through them.
Explanation:
Permeable rocks are rocks containing pores through Fluid like substances can penetrate through in the rocks. examples of Permeable rocks are ; Sandstones and Chalk
While an Impermeable rock is a rock that does not allow the flow of fluid like substance through it due to the absence of pores in its rock layers . examples of such rock are ; Clay and marble
Although some permeable rocks might exhibit low level of permeability as well but generally Rock sample with pores are classified as permeable rock layers.
Habitat destruction is the cause of the loss of species because the organism have been deprived of their living requirements.
Lederbergs' experiment of the prevalence of mutations before selective culture was proved by replica plating. They spread bacteria on the plate and allowed them to grow. Next, they stamped the growth on the new plate which was already containing penicillin. The bacteria were able to grow on this plate, even when they never exposed to the antibiotic before. This proved that some of the bacteria were already mutated and were not as a result of exposure to selective culture conditions.
