Answer:
The variation might occur in the population that leads to the evolution of the species. This variation may occur due to natural selection, mutation or recombination.
The variation might change the genotype and allelic frequency of the population and might also change the phenotype of the individual in the population. The breeding adults of the left mouthed in 1981, 1987 and 1990 shows variation and was equally opposite phenotype which is more common in the population.
Answer:
The number of bonds for a neutral atom is equal to the number of electrons in the full valence shell (2 or 8 electrons) minus the number of valence electrons. This method works because each covalent bond that an atom forms adds another electron to an atoms valence shell without changing its charge.

Start by presenting yourself, your name, where you from, etc. Then you can explain why is it important to complete all your assignments and study to get good grades... You can also talk about how High School will reflect in your future and applications for colleges. In your story write how important is to always pay attention in class and listen to your teacher.
Hope this helps!!
The correct answer is letter D. These beetles have an adapted structure. This refers to traits that they have inherited from their ancestors gene pool. Overtime the need and function for these structures are not needed by beetles in their overall survival, but the genetic code remains in their system which still gives birth to their wings that are not used anymore because of the new type of adaptation that they are going through.
