Yes, this observation is testable because you can do the experiment with your own controlled conditions and see if this with the milk would happen again.
It is qualitative observation because you use your senses such as sight, smell, touch, taste or hear to observe the results (in quantitative observations you use instruments for measurement).
Null hypothesis: The taste of the milk is the same when it is left on the counter (warm) and when it is left in the refrigerator (cold) or simply saying the place where we put milk doesn’t affect the milk taste
Hypothesis: The milk left on the counter is sour due to acidification of milk via bacteria that works on warmer place.
Independent variable (changed by a scientist in order to affect the dependent one) is a place where we put milk (temperature).
Dependent variable is milk (milk taste).
Answer:
13) Carrying capacity is the amount of biotic factors a habitat can handle.
13) Other animals, plants, and humans.
14) Weather, water temperature, and overall climate.
15) The population would increase.
Hope this helped!!! ❤️❤️❤️
<span>The answer
is a capacitor. A capacitor, in
electrical circuits, stores potential
energy in an electric field. This is similar to cell
membranes that create an electric
potential difference by pumping out particular ions (sodium ions) to the outside
of the cell hence making the inside of
the cell more electronegative relative to
the outside. This allows the cell to do work when the ions are suddenly allowed
to rush into the <span>cell.</span></span>
"When exposed to antibiotics, most bacteria in a population die but some survive and live to reproduce" is the one example that <span>illustrates Darwin's main contribution to the theory of evolution. The correct option among all the options that are given in the question is the third option or option "C". I hope it helps you.</span>
