Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.
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.
Answer:
<em>The correct option is A) Do not let your personal beliefs interfere with the truth; do not omit facts even if they contradict your hypothesis or your goals; avoid bias; do not make up data; do not plagiarize; give credit to others if you cite their work.</em>
Explanation:
Ethics and scientific research go hand in hand. If intellectual honesty and ethics are not maintained during scientific research, then this field could raise many ethical concerns.
Modifications in results are strictly against ethics during scientific research. A scientist should never try to manipulate the results so that it supports their hypothesis. Cheating or stealing other peoples work is also not acceptable in the scientific world. A scientist should always be modest.
