Water contains oxygen. The Miller-Urey experiment used some water and was energy activated using some electrical discharge intended to simulate lightning conditions, believed to induce reactions in the inanimate matter used to produce chemical reactions that created compounds believed to be consistent with what were needed to form a complete initial organism.

The electrical discharge, if intense enough, is sufficient to induce electrolysis, which separates water into H and O, but the amount of O produced was not large enough to fundamentally negatively affect the experiment. Nevertheless, the experiment used the wrong basic inanimate matter, principally the atmosphere, and did not produce the essential compounds to show viability in creating the conditions for the origin of life.

For giving you understanding ; we need Free O2 but Oxygen is also available in H20 right why dont we use it !!

As the early atmosphere was reducing as there was no free oxygen but it was later produced by chemoautotrophic bacteria !! Living thing release O2 in atmosphere thus making it oxidising in nature and then life evolves !!

Write a scientific explanation to describe the impact of the infected papaya trees on the toucan population.
seraphim [82]

The infected papaya trees will produce less carbohydrates or chemical energy for the toucan. If there were fewer carbohydrates within each papaya, the toucan's muscle cells would not be able to obtain as much chemical energy as they normally do. This chemical energy will be converted into mechanical energy or heat flow, which the toucan uses to fly.

Therefore, the lower amount of mechanical energy and heat flow from the muscle contractions, it would result into a reduced amount of kinetic energy of motion when the toucan is flying.

Which graph most likely represents a rabbit population that found a new larger habitat, but then eventually experienced an
TiliK225 [7]

Answer:

The graph illustrating such a phenomenon will show a sharp curve in upward manners in the beginning but then will  grow downwards as the predation increases.

Explanation:

When a rabbit population is introduced in a habitat, the new habitat will have abundant food for the rabbits. As a result, the population of the rabbits will grow at a much faster rate and hence the graph will move sharply upwards in the beginning. But with the passage of time, the predators of the rabbits will also increase due to the abundance of their preys. More predators will feed on more rabbits and hence a slow decline in the curve will be seen afterwards.

The answers are principles C and D. After the big bang, particles in gas clouds were closer to each other and clumped up faster. As they clumped together, they gained more gravitational force, eventually creating asteroids, stars, and planets.
