Carbon Dioxide
Explanation:
I just know
The carbon dioxide is the gas molecule most likely in the dough. Thus, option C is correct.
What is Carbohydrates?Carbohydrates is defined as biomolecule that contains carbon hydrogen and oxygen in a ratio of 2:1. Carbohydrates are mane source of energy of the body they work as fuel for the brain, kidneys central nervous system and heart muscle. [tex]Cn(H2O)n[/tex] is the basic formula for all carbohydrates . But this formula have limitation i.e it applies where same amount of carbon and water are use.
Basically, the terms carbohydrate was used to describe compounds that have really contains carbohydrates. Because they had simple formula [tex]CH20[/tex]. In modern Era carbohydrates are classified on the basis of their structure not on their formulae. Such as aldehydes and ketones are now known as polyhydroxy.
Therefore, the carbon dioxide is the gas molecule most likely in the dough. Thus, option C is correct.

How does cell volume affect nutrient exchange between the cell and its external environment?
a. Cells with a large volume and small surface area are well-adapted for nutrient
exchange.
b. Very large cells are the best adapted for nutrient exchange.
c. The ratio of cell volume to surface area determines the efficiency of nutrient
exchange.
d. Very small cells are the best adapted for nutrient exchange.
e. Nutrient exchange is not impacted by cell volume.
Answer:
d. Very small cells are the best adapted for nutrient exchange.
Explanation:
The need to be able to pass nutrients and other substances into and out of the cell limits how big cells can get. The larger a cell is, the more difficult it is for nutrients and gases to move in and out of the cell because the volume is larger than the surface area. Smaller cells can exchange nutrients with the external environment more quickly.

A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical
Answer:
Equation
Explanation:
the last word is Equation
Considering the definition of chemical reaction and chemical equation, A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical equation.
Chemical reactionA chemical reaction consists of the formation of new substances (products) from others (reagents). In this process bonds of the reactants are broken and new ones are formed in the products.
In other words, a chemical reaction occurs when the substances participating in it are transformed into different ones. The mass of the participating substances is the same before and after the reaction, that is, it is conserved because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.
Chemical equationChemical reactions are represented by chemical equations. In them, the reactants are determined, the products are predicted, and the proportions of the substances that participate in the reaction are indicated.
SummaryA chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical equation.

Mutualism
Parasitism
Answer:
predation, because it is a predator and prey
Explanation:
Dolphins chasing and eating fish would be an example of a predation relationship. This is because dolphins are the predator of all such small fishes which are living simultaneously.
What do you mean by Predators?Predators may be defined as the organisms that hunt or kill other organisms, particularly for food.
Predation is a type of interaction where one species is benefitted in the presence of another species, while the other species is harmed or lost in the presence of the first species.

Both photosynthesis and cellular respiration are part of the carbon cycle. Which statement best compares these two processes? Both release carbon dioxide as waste. Both provide organisms with usable energy. Both add bacteria to the soil. Both require fixation in order to convert molecules.
Answer:
Both provide organisms with usable energy.
Explanation:
Both photosynthesis and cellular respiration, a component of the carbon cycle provides an organism with usable energy.
Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water using sunlight to produce energy rich glucose and oxygen gas as a by-product.
During cellular respiration is an oxygen driven aerobic process in which organisms breaks down glucose to produce energy rich ATP.
Both processes furnishes an organism with energy in the end. Although, photosynthesis is an energy building process, cellular respiration breaks down materials to liberate energy. This energy is used by both plants and animals for their living activities.Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

how can a sedimentary rock become another sedimentary rock?PLEASE ANSWER!!!!
Answer:
the rock breaks down and goes through the 5 step process to become a sedimentary rock again.
Explanation:
1) Weathering (making the sediment by breaking down or dissolving preexisting rocks or living organisms)
2) Erosion (picking up the sediment by water, wind, or glaciers)
3) Transportation (moving the sediment by water, wind, or glaciers)
4) Deposition (depositing the sediment)
5) Lithification (turning the sediment to rock).

Which of the following is true of the Celsius scale A.) 212° is the boiling point of water b.) 0° is absolute zero c.) 0 degrees is the freezing point of water or D .) 32° is the freezing point of water
Answer:
The correct answer is C., or ¨0 degrees is the freezing point of water¨.
0 degrees is the freezing point of water is true about the Celsius Scale. Therefore, option (C) is correct.
Water freezes at "zero degrees" on the Celsius scale. Under ordinary climatic conditions, water's freezing point is 0 degrees Celsius and its boiling point is 100 degrees Celsius. Many countries use this scale to measure temperature.
However, the Fahrenheit scale, used mostly in the US, has different freezing and boiling points for water. Water freezes at 32 degrees Fahrenheit and boils at 212. Therefore, option (C) 0 degrees is the freezing point of water is correct.

Explanation:
The Ebola virus disease is a harmful viral hemorrhagic disease caused by ebolaviruses, which have a high risk of death (approximately 20% to 90%). In December 2019, the U.S. Food and Drug Administration (FDA) approved Ervebo, which is the first vaccine approved by the FDA with the aim to prevent the Ebola virus disease. Nowadays, there is no antiviral treatment approved by the FDA for patients with Ebola; however, there are two antiviral drug treatments named regeneron (REGN-EB3) and mAb114, which have shown good efficacy to treat the Evola virus. Currently, both antiviral drugs are being used in patients with Ebola.
