Psychology emerges as a separate discipline. During the mid-1800s, a German physiologist named Wilhelm Wundt was using scientific research methods to investigate reaction times. He later opened the worlds first psychology lab in 1879 at University of Leipzig.
The correct answer is that t<span>here are probably very few astronauts with twin siblings.
We have to take into consideration that astronauts are a very small group of people and that there is only a small chance that one of them has an identical twin. Although the tests can be hard to do and categorize these kinds of tests and measures are not unethical as long the scientists have the person's permission. Currently, we possess the technology and resources to keep a person in space for a year, but it will be really hard to find more astronauts that have identical twins.

Answer:
The process by which organisms that are better suited to their environment than others produce more offspring. As a result of natural selection, the proportion of organisms in a species with characteristics that are adaptive to a given environment increases with each generation.
Explanation:
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.
