the breaking of a large organic molecule into smaller individual subunits involves multiple ________.
The breaking of a large organic molecule into smaller individual subunits involves multiple hydrolysis reactions.
HYDROLYSIS:Hydrolysis is a type of reaction in which water is used as a reactant to break down chemical bonds of a large molecule.
As the name implies: hydro meaning water and lysis meaning break down. Larger molecules are disintegrated into two or more simpler molecules by reacting with water.
Therefore, it can be said that the breaking of a large organic molecule into smaller individual subunits involves multiple hydrolysis reactions.

What is the voltage of a galvanic cell made with magnesium (Mg) and gold
(Au)?
O A. 4.2 V
OB. 0.54 V
O C. -0.54 V
O D.-4.2 V
A. 4.2 V is the voltage of a galvanic cell made with magnesium (Mg) and gold(Au).
What is the voltage of a galvanic cell made with magnesium?The bigger the reduction ability, the more likely the steel is to be reduced and act as the oxidizing agent. Returning to the copper-magnesium galvanic cellular, the same old electrode potential of copper is 0.337 volts, whilst the standard electrode capability of magnesium is -2.370 volts.
Cell voltage is also known as cell ability (E) and electromotive force (emf). the electrical voltage or ability is measured in volts (V). The volt is related to strong values, joules (J), and electric powered fee, coulomb (C). The connection between these is defined with the equation: 1J=1C×1V.

1. Carbon dioxide. Water • Energy - Sugar • Oxygen
2. Sugar + Oxygen - Water + Carbon Dloxide + Energy
In the second reaction shown here (cellular respiration), which of these descriptions compares the products and reactants?
Water and carbon dioxide are changed into oxygen and glucose during photosynthesis. Oxygen and glucose are transformed into water and carbon dioxide during cellular respiration
What cellular process is the opposite of photosynthesis?The reverse of photosynthesis is the process of respiration. Animals like us get their energy from sugars. In cells, the mitochondria are where respiration occurs. During breathing, oxygen and sugar combine chemically to break down sugar.
Biochemical processes like photosynthesis and cellular respiration move matter and energy across the biosphere. Cellular respiration generates carbon dioxide, water, and ATP, which serve as the precursors for photosynthesis along with sunlight.
Hence, cellular respiration is reversal of photosynthesis.

Answer:

Explanation:
the figure shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. why are they different?
Absorption spectrum for chlorophyll a is different from the action spectrum for photosynthesis due to their usage.
The absorption spectrum for chlorophyll a is different from the action spectrum for photosynthesis because an absorption spectrum shows all the colors of light that is absorbed by a plant while on the other hand, an action spectrum shows all the colors of light that are used in photosynthesis.
Chlorophyll is a green pigment which absorbs all spectrum of light except the green but in the absorbed lights, red and blue spectrum participate directly in the process of photosynthesis so we can conclude that absorption spectrum for chlorophyll a is different from the action spectrum for photosynthesis.

Answer to the following questions in complete sentences.
What is seen when phenolphthalein is added to distilled water?
Why do you think you had to use distilled water, which is pure water, rather than tap water?
What is seen when phenolphthalein is added to the filtered water with chalk? with calcium hydroxide?
What does it mean that the filtered water samples reacted with phenolphthalein?
When phenolphthalein is added to distilled water, no changes will be observed in the reaction.
What do you mean by Phenolphthalein?Phenolphthalein may be defined as an organic compound of the phthalein family that is widely employed as an acid-base indicator.
The distilled water is free from any impurities because it is sterilized before use. The pH of distilled water is neutral, while the pH of tap water ranges from 6.5 to 8.3, which affects the products of the given reactions.When phenolphthalein is added to the filtered water with chalk or calcium hydroxide, it gives a pink color. Filtered water samples mean those water samples which are filtered and the impurities are removed by physical appearance only. It overall does not change the properties of the water sample.Therefore, all the questions are described above one by one.

1. Colorless solution.
2. To avoid interference from impurities in tap water.
3. Pink color (chalk), no reaction (calcium hydroxide).
4. Presence of alkalinity in chalk-filtered water.
1. Phenolphthalein in distilled water is colourless. Pure distilled water does not contain contaminants that might react with phenolphthalein to change colour.
2. Phenolphthalein readings are accurate with distilled water. Tap water may include minerals, salts, and contaminants that react with the indicator and cause a misleading or confusing colour shift. Distilled water eliminates these interferences, revealing the indicator's behaviour.
3. Phenolphthalein turns chalk-filtered water pink. Calcium carbonate in chalk forms calcium hydroxide with water. This reaction raises water alkalinity, turning phenolphthalein pink.
4. The pink colour of chalk-filtered water samples suggests alkalinity, but calcium hydroxide does not modify the colour and phenolphthalein does not react. This phenolphthalein indicator detects alkaline characteristics in water samples.

what type of muscle cells are arranged in sheets or layers with adjacent muscle cells electrically connected by gab junction
Answer:
smooth muscle
Explanation:
Smooth muscle fibers are spindle-shaped and, unlike skeletal muscle fibers, have a single nucleus; individual cells range in size from 30 to 200 μm. Smooth muscle fibers are often found forming sheets of tissue and function in a coordinated fashion due to the presence of gap junctions between the cells.
