They have created amino acids by replicating early earth conditions. This experiment was held by Stanley Miller and Harold Urey
The 2 processes currently bringing the most profound change to the developed democracies are devolution and integration.
Osmosis can be demonstrated in the lab by observing the movement of solvent (water) to the external media for D samples.
<h3>What is Osmosis?</h3>
Osmosis can be defined as the movement of the solvent molecules (e.g. water) through a selectively-permeable membrane.
Osmosis is also produced from a medium of higher solute concentration to a medium of lower concentration, which does not require energy to carry out this type of cellular transport.
The cells use the physical process of osmosis in order to maintain the state of internal equilibrium (homeostasis) and perform different metabolic functions such as, for example, growth, differentiation, uptake of nutrients, etc.
In conclusion, osmosis can be demonstrated in the lab by observing the movement of solvent (water) to the external media for D samples.

Answer:
The correct answer is option c.
Explanation:
Starting from the initial primates to the hominids, and eventually, to Homo sapiens, the brain of humans has grown spontaneously. The volume of the brain has increased with the evolution of humans, that is, starting from about 600 cubic centimeters in Homo habilis to 1600 cubic centimeters in Homo neanderthalensis. The Homo neanderthalensis was the hominid with the largest size of the brain, that is, with the maximum cranial capacity. The enhancement in the size of the brain ceased with neanderthals. After that the shrinking of the brain size took place.
The correct answer is B. Oxygen.
Oxygen, as a part of the atmosphere, also participates in UV protection, besides being necessary for breathing.
