Answer: Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Answer:
Among the different types of scientific knowledge hypotheses are likely to be modified or discarded most frequently. Long ago in the 1600's scientists discarded the phlogiston theory because the new evidence didnt support it.
Explanation:
Hypothesis is the assumption of something possible or impossible to draw a consequence and is provisionally established as the basis for an investigation and which can confirm or deny its validity. For this reason, within scientific research, hypotheses are so important and so changeable that they are modified or discarded more frequently within scientific knowledge.
Based on a work by Johann Joachim Becher, the German scientist Georg Ernst Stahl created the phlogiston theory that said combustion occurred with certain materials because they had an “element” or a common flammable principle that was released at the time of burning . This theory was abandoned because there was no evidence, even through scientific experiments, to prove that this theory is true.
Hypotheses are likely to be modified or discarded most frequently in scientific knowledge. Phlogiston theory was discarded due to evidence contradicting its predictions.
Among the different types of scientific knowledge, hypotheses are likely to be modified or discarded most frequently. Long ago, in the 1600s, scientists discarded the phlogiston theory because evidence contradicted the predictions made by the theory. Phlogiston theory proposed that a substance called phlogiston was released during combustion, but experiments showed that substances gained weight instead of losing weight during combustion.

The three-dimensional geometry of the atoms in the molecule
The ionic charge on each atom within the molecule
The way atoms share electrons to be connected to one another within the molecule
Answer:
The total electron configuration of each atom in the molecule
Explanation:
Electron distribution into energy levels or sublevels of atoms can be shown with different notations or electronic configuration. One of them is the lewis dot structure.
The Electron Dot Notation or Lewis Dot structure is a notation which shows only the chemical symbol of the element surrounded by dots to represent the valence electrons. The chemical symbol stands for the nucleus and all electrons except the valence ones. The dots are arranged at the four sides of the symbol in pairs called lone pairs Those that are unpaired are called odd electrons.
Answer:
In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs. A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction.
Explanation:
Your answer is: Galium
After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. the decay that is present is gamma decay because gamma decay has photons which has no mass unlike alpha and beta decay.
