Yes, you are right. A student reported that a limp stalk of celery became crisp when placed in ice water. This is an example of an observation.

Observation is the process of actively acquiring information from a source of study. When the observation is collected using the senses, it becomes an empirical evidence. However observations are also scientifically recorded using various scientific instruments for precision and accuracy. Example, use of thermometer to record the room temperature.

Why does darkness affect the light-independent reactions of photosynthesis?
notsponge [240]

Answer:

The correct answer would be Light independent reactions require the energy gathered in the thylakoids.

Photosynthesis can divided into two sub-processes or reactions:

Light-dependent reaction: It converts solar energy into chemical energy that is, ATP (adenosine triphosphate) and NADPH with the help of photolysisis of water. It takes place in thyllakoid membrane of the chloroplast.

Light-independent reaction: It fixes carbon obtained from carbon dioxide into the food or glucose with the help of enzyme RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase).

It takes place in the stroma of the chloroplast and does not require the involvement of light however, it requires the products (ATP and NADPH) of the light reaction.

Fixation of 1 molecule of glucose requires 6 molecules of carbon dioxide, 9 molecules of ATP and 6 molecules of NADPH.

So, darkness indirectly affects the light-independent reaction.

What does this animation mean when it says that ATP is like a rechargeable battery?
Solnce55 [7]

I dont know what animation you mean about but i will give my opinion.

ATP are used for energy, they are made inside mitochondria. Mitochondria use oxygen and food to make ATP, which is maybe what u mean by rechargable is because whenever you eat, the mitochondria will produce energy again and again.

What happens when the parasympathetic nervous system is activated
kolezko [41]

Answer:

Body functions stimulated by the parasympathetic nervous system (PSNS) include sexual arousal, salivation, lacrimation, urination, digestion, and defecation. The PSNS primarily uses acetylcholine as its neurotransmitter. Peptides (such as cholecystokinin) may also act on the PSNS as neurotransmitters. The parasympathetic nervous system is composed mainly of the cranial and sacral spinal nerves.

Hope this helps! If so please mark brainliest!
