Answer:
B. Is what the scientists manipulate in the experiment.
Explanation:
The Independent variable is not dependent, or doesn't rely, on another variable in the experiment. So, it would make the most sense that they would manipulate the Independent so that they can watch and see how the dependent variable reacts to the manipulation, or the change, in the independent variable.
The correct answer is: A. A watery mixture of partially digested food released by the stomach into the intestines
Chyme or chymus is formed in the stomach, during the process of digestion (it takes 40 minutes to 3 hours to be produced) , and it is transported to the small intestine-duodenum.
In the beginning of the digestion (in the mouth), mixture of food and saliva called bolus, is formed. Mechanical and chemical breakdown of a bolus creates chime which is ready for the extraction of nutrients from it.
Similarities: Natural Selection and Artificial Selection both result in the alteration of the gene pool. It can also change phenotypes of different species'.
Differences: Artificial Selection is when a specific trait is not wanted, and so it is not bred.
For example, humans did not like how yellow peas looked. They liked the healthy looking green better. So, they killed the yellow peas, and bred the green peas with other green pea plants, and right now it is almost completely out of our gene pool.
Natural Selection is when something naturally occurs, such as a natural disaster, famine, plague, invasive species introduction.
For example, if 10 camels lived in a desert, but one of them didn't have as good of a metabolism and stayed full longer, then that one would survive, while the others might not.
