Answer:

The correct answer is that it is held constant throughout the experiment.

Explanation:

A variable that is maintained constant all through the experiment is known as a control variable, and it is not the main concern in the outcome of the experiment. In an experiment, if there is any kind of change in a control variable it would lead to an error in the correlation of independent variable to the dependent variables, thus, affecting the results.

is held constant throughout the experiment.

the control group is used as a foundation for your experiment so you know what changes what and how to manipulate the independent variable.

Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach
leva [86]

Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.

The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.

Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.

Because it's vital to the survival of all species, not just human, that we have resources such as food and water. Also that those resources be clean and healthy. We also need to manage resources such as oil to make sure there are fewer wars like the ones happening in the Middle East. If you need anything else just message me.
