Answer:
Angle of light source
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment in order to bring about a measurable response, which is the dependent variable.
In this question, a student wants to investigate the effects of phototropism in bean plants. She places a light source directly above one plant, at a forty-five degree angle to another, and at a ninety-degree angle from the third. This shows that the variable being manipulated (independent variable) is the ANGLE OF THE LIGHT SOURCE.
Answer:
Explanation:
There is a total of 38 ATP produced. ATP is produced from 3 different steps. The first step is Glycolysis which produces 2 net ATP. Next, is the KREBS cycle (aka the Citric acid cycle) which also produces 2 ATP. The final step is the Electron Transport Chain, which produces 34 ATP.
Anabolic reactions require an input of energy, while catabolic reactions release energy. When talking about the metabolism, ATP is released through catabolic reactions. To grow and build muscles, for example, anabolic reactions are need (because you need food to gain muscle mass).
Anaerobic respiration means that NO OXYGEN is present while aerobic respiration takes place in the presence of oxygen. It is important to note that ONLY GLYCOLYSIS can occur during anaerobic respiration. Also, fermentation occurs during anaerobic respiration. There are two types of fermentation; lactic acid and "alcoholic". basically, lactic acid fermentation produces, well, lactic acid (which is used in yogurt and it's also the cramps you feel while running the mile in gym). Alcoholic fermentation is what is used to make alcohols like isopropanol or drinking alcohols like vodka.
Hope this helps :)
Answer:
An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
