Tim makes a volcano demonstration for a class. He crafts the volcano out of clay, and then pours vinegar into the baking soda th

at is inside the volcano. What would be the best way for Tim to turn this demonstration into an experiment? He could pour the same amount of vinegar into several different volcanoes containing baking soda, repeating the demonstration. He would be answering the question “What happens when I pour vinegar into baking soda?” He could time how long the volcano bubbles after he pours the vinegar into the baking soda. He would be answering the question “How long will my volcano bubble?” He could measure how far the bubbles travel across the laboratory table after he pours the vinegar into the baking soda. He would be answering the question “How far will bubbles travel across a flat surface?” He could add different amounts of vinegar to the same amount of baking soda and time how long it bubbles each time. He would be answering the question “How does increasing the amount of vinegar affect the amount of bubbles that form?”

More bubbles will form if more vinegar is added

Answer:

Use several volcanos

Explanation:

An experiment has to take into consideration the variability of the process because each time it is run you will get a slightly different result. The more repetitions you have, the closer you will get to a better understanding of the mechanism you are studying. So the best way for Tim to turn his demonstration into an experiment would be the first choice, by using three volcanos, or preferably more.

The nasal cavity is divided into left and right portions by the
blondinia [14]

Answer:

The correct answer will be- nasal septum

Explanation:

The nasal cavity is the hollow space or cavity connected to the two nostrils which allow the inhalation and exhalation of the air into the nose.

The nasal cavity is divided into left and right portion by a cartilaginous bony structure called nasal septum. The nasal septum lies in the central position and divides the nasal cavity into symmetrical portions.  

Thus, the nasal septum is the correct answer.

const2013 [10]

Answer:

The group needs to find signs of apical dominance, growth in response to light, vascular tissue differentiation, formation of lateral and adventitious roots, etc.

Explanation:

Lanolin is a solvent used to study physiological processes in plants by diluting hormone growth regulators (in this case, indole acetic acid). Indole acetic acid (IAA) is the most important auxin hormone in plants. Auxins are essential plant hormones synthesized in expanding shoot tips that move down the stem to the roots. These hormones coordinate cell division, elongation and identity during plant body development. IAA hormone is well known to regulate different plant developmental processes including, among others, apical dominance (where the central stem grows more strongly than other lateral stems), tissue differentiation, stem elongation, phototropism (growth in response to light) and gravitropism (response to gravity). For instance, under the application of IAA, it is expected that bean stems grow to imitate the response to light (phototropism) by bending away from the side where lanolin was applied.
