In order to actually start up the Scientific method you must "Observe" whatever it is you want to question.
Answer:
The mutations that were found in the parents were mostly somatic mutations
Explanation:
It has been mentioned in the question that leukemia was mainly found in the persons who were directly exposed to the radiation and it was absent in their children so this fact suggests that the mutations that were found in the parents were mostly somatic mutations and thus they are not transferred to the children from their parents. As these mutations were induced due to exposure of radiation so it was induced mutation. And such induced mutations do not get inherited to the offspring.
All of the systems that are aroused by the <span>sympathetic nervous system</span> are relaxed by the parasympathetic nervous system.
<span>autonomic nervous system (ANS) is a part of the central nervous system that controls all parts that the human cannot have a control on (which are done automatically) like heart rate and breath
ANS is divided in two opposite systems: sympathetic and parasympathetic:
</span>Parasympathetic nervous system: caracterized by the tag "<span>rest and digest" it decreases the heart rate, blood pressure, and breath. It increases the gastrointestinal motricity, letting the organism resting (this happen after a meal).
</span>Sympathetic nervous system: caracterized by the tag "fight or flight" it increases the heart rate, blood pressure, and breath. It decreases the gastrointestinal motricity, letting the organism focus on its environment (this happen when we are in danger).
Fermentation is the process by which a carbohydrate molecule is broken down into alcohol and carbon dioxide in the absence of oxygen. During this process, two molecules of ATP is produced. In the absence of oxygen, pyruvate formed from glycolysis will undergo fermentation process. During the process of fermentation, NADH from glycolysis will be converted back to NAD+. This is necessary in order for glycolysis to continue. Thus, fermentation regenerate more NAD+ and only a few molecule of ATP.
Answer:
Natural selection and selective breeding can both cause variations in animals and plants. The distinction separating the two is that natural selection occurs naturally, but selective breeding only happens when humans intervene. For this purpose, selective breeding is seldom called artificial selection.
