Answer:
The history of Earth covers approximately 4 billion years (4,567,000,000 years), from Earth's formation out of the solar nebula to the present. Earth formed as part of the birth of the solar system: what eventually became the solar system initially existed as a large, rotating cloud of dust and gas.
Explanation:
The brown rabbits will reproduce effectively whereas the white rabbits will not survive in the events when the winter will get warmer with warmer temperature lasting longer.
Explanation:
The theory of Darwin suggests the Survival of the Fittest. The brown rabbits due to their adaptive skin color to the warmer temperature that is summer when everything in the environment goes pale due to heat will help them survive.
Similar in context, winter brings snow and so the white rabbits will thrive in more. But when the natural pursuit of temperature or climate changes, the brown rabbit lasting longer in warmer temperature will survive more with white ones wiping out.
Bacteria in a unicellular organism that has an archaic structure but is very smart, specifically in antibiotic resistance.
Bacteria have several characteristic or "weapons" to fight antibiotics:
Bacteria has a cell wall which do not allow toxic substances to go in.
Bacteria has transporters which expulse the antibiotic molecules that enter into the cell.
Bacteria has enzymes that break the antibiotic molecules and make them inactive
Bacteria can mutate (change) itself so, and by the way the antibiotic sites, so the molecules cannot fix it. And that is the most problematic.
Bacteria can transmit it resistance mechanism to other bacteria, even if they are not from the same family.
<span>A polypeptide is a single linear chain of many amino acids, held together by amide bonds. A protein consists of one or more polypeptides (more than about 50 amino acids long). An oligopeptide consists of only a few amino acids (between two and twenty). </span>

The reasoning behind this could be a part of personal beliefs and or the opinion of that person viewing it as animal abuse. this point of view is based on the individual.
