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).

The options are incorrect. The correct question with options is:
Which of the following statements is true concerning catabolic pathways?
A. They combine molecules into more energy-rich molecules
B. They supply energy, primarily in the form of ATP, for the cell's work
C. They are endergonic
D. They are spontaneous and do not need enzyme catalysis
E. They build up complex molecules such as protein from simpler compounds
Answer:
B. They supply energy, primarily in the form of ATP, for the cell's work
Explanation:
Catabolic pathways are the metabolic pathways that breakdown the complex molecules into simpler substances. The chemical reactions of catabolic pathways are mostly exergonic with a negative value of free energy change.
The released energy is stored in the form of ATP molecules. The energy-releasing reactions of catabolic pathways supply the cells with ATP molecules to perform the functions. For instance, breakdown of glucose into CO2 and H2O during aerobic cellular respiration is a catabolic process and forms as many as 32 ATP molecules.
Answer:
The diagram below shows a cross section of a plant leaf. How does the structure marked X contribute to the survival of the plant? It allows the intake of gases necessary for photosynth
The weight of an object is the force of gravity exerted on that
object and the mass of an object is the amount of matter it has, and it
stays the same wherever you are, regardless of gravity.
So, here the mass of object is 40 kg on earth,
it means it has mass of 40 kg on moon also, but when we are calculating the
weight of an object we used the following formula,
F=mg
Where F is the weight of an object in Newton
and m is the mass of object in kilogram and g is the gravity
Now here gravity on the moon is 1.6 m/s2 and m
is 40 kg
So, F = 40 x 1.6
<span>F = 64 N</span>
<span>mass of the object on moon is 40kg and weight of an object on moon is 64N.</span>
