Answer:
Since you did not provide the specific molecules, here are some ways that glucose is used for synthesis:
Protein molecules - Glucose regulates protein synthesis through AMPK (Activated Protein Kinase) pathways. AMPK is activated by cellular energy via changes in AMP levels resulting from energy.
Gluconeogenesis Pathway - The process where glucose is synthesized using pyruvate and lactate precursors from non-carbohydrate metabolites, amino acids, and glycerol (derived mainly from metabolized fat).
Fatty Acids - Metabolized into pyruvate using glycolysis in the cytoplasm, oxidized pyruvate generates ATP in the mitochondria. During the fed state the glycolytic products synthesize fatty acids through lipogenesis.
Amino Acids & Lipids - Through photosynthesis in plants, glucose joins with nitrates in the soil to create amino acids. The amino acids combine during protein synthesis and glucose is converted to lipids within the plant seeds.

Can mathematical representation support that momentum is conserved when there is no force on the object?
The momentum of a system is conserved when there is no external force applied on the object. This can be represented by mathematical expression: (m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂).
What is Momentum?
Momentum is a property of a moving object which the object has by the virtue of its mass and motion. It is the product of the body's mass and velocity.
Conservation of linear momentum expresses that a body or system of bodies in motion retains its total momentum. The product of mass and vector velocity constant, until and unless an external force is applied on it. In an isolated system, there is no external force, so momentum is always conserved.
To have the momentum conserved, a system must meet two requirements:
1. Total Mass of the system must remain constant during the interaction.

Answer:
1. "Atmospheric humidity is usually measured with a psychrometer and can be described in several ways. The dew-point temperature and the absolute humidity represent the actual moisture in the air, while the relative humidity indicates the degree of saturation at a given temperature."
2. "The dew point is the temperature to which air must be cooled to become saturated with water vapor."
3. "When air has reached the dew-point temperature at a particular pressure, the water vapor in the air is in equilibrium with liquid water, meaning water vapor is condensing at the same rate at which liquid water is evaporating."
4.
"The state or process that occurs when no more of something can be absorbed, combined with, or added. When the dew point equals the air temperature, the air is saturated and the relative humidity is %100.
5. "It is a common misconception that changes in temperature will affect the dewpoint. It is important to remember that dewpoint is independent of the ambient temperature. Only changes in pressure or the actual amount of water vapour present will affect the dewpoint."
6. "When the dew point equals the air temperature, the air is saturated and the relative humidity is %100."
7.
8. "Relative humidity (RH) (expressed as a percent) also measures water vapor, but RELATIVE to the temperature of the air. In other words, it is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature."
9. "The term relative humidity (RH) expresses the relationship between the moisture content of air at a certain temperature and the moisture content of moisture-saturated air at the same temperature. It is given as a percentage from 0 to 100. 100% RH means that the saturation with moisture, the dew point is reached."
10. "The lower the temperature of air the less capacity it has to hold moisture in a vapor state."
11. "Warm air can possess more water vapor (moisture) than cold air, so with the same amount of absolute/specific humidity, air will have a HIGHER relative humidity if the air is cooler, and a LOWER relative humidity if the air is warmer."

the small fish known as the cleaner wrasse is found in a mutualistic relationship with larger fish species. what benefit does the cleaner wrasse obtain from the relationship?
The benefit of reliable food sources is the cleaner wrasse obtained from the relationship.
In this relationship, the cleaner wrasses establish "cleaning stations" where they consume parasites and dead skin cells from obedient reef fish. By getting rid of those parasites, the reef fish benefit, and the wrasses get a new source of food. A reciprocal relationship exists between cleaner fish and larger fish. The reason for this is that the cleaner fish feeds on the large fish's dangerous parasites and other small sources of food.
The larger fish benefit because they no longer have these parasites on them, and the cleaner fish get a meal as a result. More often than not, larger fish wait in "cleaning stations" for cleaner fish to come and remove these things from them. Even cleaners can be found among some small shrimp.

There is no stored nourishment in the spores of seedless plants to aid in the growth of a new plant. The ability of animals to disperse seeds is another benefit of seed plants.
An embryo starts to develop throughout the process of germination into a new plant known as a seedling. Because of the aforementioned factors, seeds had a better probability of reproducing than seedless plants (spores).
