An example of a population in which evolution could take place in a relatively short period of time could be pathogenic bacteria exposed to antibiotics.
Answer: Option A
<u>Explanation:</u>
Evolution if takes place within a short period of time say the next generation that is called as micro evolution. This is caused when a specific organism exposed in a different environment at once modifies its genes to suit the new environment. This phenomenon can be very well seen in the pathogenic bacteria which are exposed to antibiotics.
When an antibiotic is prescribed to bacteria initially it nullifies its effect by destroying it. When continuously exposed to a certain antibiotic some bacteria dies but there are few which becomes resistant to it and survives. This on the other hand multiplies producing a generation that can’t be touched by the antibiotic.
The answer is base pairs.
Answer:
Darwin was able to explain evolution with evidence, something Lamarck did not do.
Explanation:
Lamarck and Darwin both were scientists who tried to understand the concepts of evolution. Lamarck's theory of evolution was based upon how living organisms vary during their lifetime, and after that they pass these changes to their offspring. While on the other hand Darwin's theory was very much based upon evidences and practical explanation that is why his theory became accepted and Lamarck's wasn't.
The process is called precipitation. This is when water released from clouds in the form of rain,freezing rain,sleet,snow or hail. It is the primary connection in the water cycle that provides delivery of atmospheric water to the Earth.

Groups of atoms held together by energy are called a molecule. The energy or force holding the atoms together is called a Chemical Bond,
The Covalent bond involves the sharing of 2 electrons.
Molecule- One or more atoms make up molecules. They may have the same atoms or different atoms if they have more than one. Biological molecules like DNA and proteins can include thousands of atoms.
Chemical Bond- Chemical bonding is the process through which two or more atoms, molecules, or ions establish a chemical link to create a chemical compound.
Electron- A negatively charged subatomic particle known as an electron can either be free or attached to an atom (not bound).
