Answer:
The reason why is because in the process of reproduction; there are some mistakes in DNA replication (out of billions of base pairs about 120,000 mistakes). This is what brings us so much variation in organisms.
what will happen to a population of organisms that are in an oxygen rich environment. (Double click the story board to draw on it)
Answer
I'll assume this means adding additional oxygen to the atmosphere.
Paper airplanes now fly farther. With all that extra air, the air pressure near the surface increases significantly. Gliders, parachutists, birds and paper-plane hobbyists enjoy greatly improved performance.
Everyone gets better gas mileage. Oxygen-enriched air improves engine performance by producing hotter reactions and reducing the proportion of nitrogen, which reduces heat transfer (Page on Energy.gov)
Higher elevation Biomes become inhabited by more vertebrates. Areas such as the high Himalayas or high Andes are no longer off-limits to animals without special adaptations to increase their levels of hemoglobin.
Insects of unusual size. Many insects rely on gaseous diffusion to for respiration, therefore the maximum body size depends on the proportion of oxygen gas in the atmosphere. Most bugs get bigger, some smaller (see Atmospheric oxygen level and the evolution of insect body size)
Everyone feels more alert, active, and happier. All that fresh oxygen improve our cognition, alertness, and physical performance. As a result, most athletic records would likely be broken by oxygen-enriched athletes.
We get sick less often. Neutrophils, soldiers of the immune system, destroy bacteria by using NADP oxidase to pump ions into, and disrupt, intruding cell's membranes causing rupture. More oxygen, more oxidase. (Page on Nih.gov)
We die younger. Free radicals (i.e. O2-) are thought to exacerbate the aging process through Oxidative stress, which interferes in numerous cellular processes: protein production, DNA replication, intercellular communication, and are also thought to contribute to MS, Alzheimers, Parkinsons, and a host of other ailments.

biology is the correct answer
Before it was known as "science," this branch of study was called Natural Philosophy.
What do you mean by science?The pursuit of knowledge is what is meant by the term "science." This approach describes and provides an explanation for natural occurrences based on observations and experiments. The term "science" can also refer to the arranged body of information that has been accumulated by individuals via the application of that system.
A person who works in a particular field of science and possesses in-depth knowledge about that field is called a scientist. Or, to be more general, anyone who studies or works in a scientific field is considered to be a scientist.

Which molecule supplies chlorophyll with electrons
In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. The energized electrons from the chlorophyll molecules flow down a transportation chain to a compound called nicotinamide adenine dinucleotide phosphate or NADP.
▪▪▪Cutest Ghost▪▪▪Water is the molecule that supplies chlorophyll with electrons.
What happens during photosynthesis?Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose (sugar) and other carbohydrates. This process also produces oxygen as a byproduct.
During the process of photosynthesis, chlorophyll absorbs light energy, which is used to split water molecules into oxygen and hydrogen atoms. The hydrogen atoms are then used to generate ATP and NADPH, which are used to power the process of carbon fixation. The oxygen atoms are released as a byproduct of water splitting and become a part of the oxygen in the Earth's atmosphere.

Each X shows the location of an archer's arrow on a bull's-eye target. The archer was aiming for the center circle. X xx X x x Which words best describe the archer's results?
Low precision and low accuracy best describe the archer's results. So the correct option is A.
Who is an archer?Archery is a sport that involves firing arrows with a bow at inanimate objects or animals during a hunt.
With the exception of Australia, the bow has been a primary tool of combat and the hunt from prehistoric times.
Ancient Egyptians and Greeks also engaged in recreational archery in addition to military archery, an example of the latter being the contest in which Odysseus triumphed and gained Penelope's hand.
Large portions of Asia were ruled by horse-mounted archers such as the Huns, Seljuq Turks, Mongols, and others for around 15 centuries beginning in the first century CE.
During the Hundred Years' War (1337–1453), English longbowmen earned magnificent military successes, while the crossbow gained popularity throughout continental Europe, particularly in Switzerland, some regions of Germany, France, and the Low Countries.
Therefore the correct option is A.
