Answer: 2 cells, Prophase 1, chromosomes lining up at equator of cell, anaphase 1, four times
Explanation:
<span>A light microscope uses focused light and lenses to magnify an object. Light microscopes come in several forms. (1) Simple light microscopes use a single lens to magnify an object and cannot reach high magnification just like a handheld lens whose highest clear magnification in the best conditions is 25x. (2) Compound light microscopes use two sets of lenses - an objective lens and an eye piece. This is the type of light microscope whose magnification power reaches between 1000x and 2000x.</span>
Answer: Autonomic nervous system is made up of 3 divisions; Sympathetic nervous system, parasympathetic nervous system and sympathetic division. All these divisions are involuntary actions where parasympathetic is ultimately responsible for the "rest and digest" part of it. When the body is at rest the parasympathetic nervous system inhibits or lowers high energy requiring bodily functions.
This nervous system will lower any fight or flight response actions such as the release of epinephrine into the blood and enable digestion, urination and defeacation. When engaged in digestion you feel relaxed and at rest, this is solely due to the parasympathetic nevous system.
The correct answer is C. New experiments can affect previous scientific explanations.
Explanation: An experiment is a way of checking a phenomenon under specific conditions to analyze its effects or to verify a hypothesis. An example of this is the statement because before the seventies it was believed that new neurons could not be generated in an adult brain, however, after conducting an experiment on songbirds it was found that it was possible. Therefore, it confirms that new experiments can affect previous scientific explanations because new experiments can test hypotheses that modify previous explanations. So the correct answer is C. New experiments can affect previous scientific explanations.
