Answer:
A factor that is purposely left the same.
Explanation:
A controlled variable should not be changed throughout an experiment or else it will affect the outcome of each individual trial.

Alimentary canal (digestive tract) is the gut of animals (including humans) which includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus. The function of the alimentary canal is to carry food from the digestion to the excretion.</span>
Answer:
Explanation:
The lamp and the ice bag were at the same place.
Sounds like the experiment was intended to show on a small scale ocean currents from the poles to the equator and back to the poles. The bag of ice would simulate the cold at the poles while the lamp would simulate the heat provided by the sun near the equator. With that in mind, let's look at the possible flaws and see what is likely.
Not enough ink was added.
* If you can see the ink, then there's enough ink. So this isn't the correct choice.
Not enough water was taken.
* Possibility there wasn't enough volume of water to setup a current, but not too likely since the baking dish was filled. So let's look further.
The dish was too small for the experiment.
* Same as above. It might be this, but there's something more likely.
The lamp and the ice bag were at the same place.
* This sounds like a winner. In the real world, the poles are cold and the equator gets more sunlight. So there's a temperature gradient. In the described setup, both the heat sink (the bag of ice) and the heat source (the lamp) were at the same location.
I believe that Air moves from the larynx, through the Trachea, and then into the lungs. Trachea also known as the windpipe provides the flow of air to and from the lungs for cellular processes such as respiration. The lower respiratory system is made up of the trachea, larynx, the bronchial tree, the right lung and the left lung.
No they don’t because the atcg sequence doesn’t show the dna functions in an organism
