can flow
is composed of moving particles
cannot be compressed
B hydrogen
C oxygen
D nitrogen
The correct answer is option B, hydrogen.
The majority of the atmospheric gases are found in the sea water solution. In supplementation to oxygen and nitrogen, the most profusely found gas in the atmosphere, that is, carbon dioxide is found in the ample concentrations in the ocean waters.
However, hydrogen is not present, and if found it is found in minute concentration. Of the gases, nitrogen is the most abundant gas found in seawater, while oxygen is the second most abundant, and carbon dioxide is the most soluble gas, and one of the various constituents, which influences the pH balance of the ocean.
The answer is B. hydrogen.
Answer:
Air cells of dough are filled with CO2.
Explanation:
Flour, water and yeast are important parts of bread dough. When we mix these the yeast enzyme will breakdown the satarch into simple sugars and metabolize the sugars to produce CO2 and ethyl alcohol into the existing air bubbles in dough.
Fermentation helps in producing the strong and elastin gluten to held the CO2 within the bubbles and inflate it. The more the air cell filled the more will be the bread dough rise.
Answer:
Presence of CO2 in the dough.
Explanation:
Yeast cells thrive on simple sugars. As the sugars are metabolized, carbon dioxide and alcohol.
chemical process known as fermentation.
Equation of Fermentation reaction:
C6H12O6(s) --> 2C2H5OH(aq) + 2CO2(g)
Tiny air cells fill with carbon dioxide are released into the bread dough, making it rise.
The options attached to the question above are given below:
A. All living and nonliving things consist of one or more cells.
B. Cells and living organisms are spontaneously created.
C. Cells are the most complex unit of structure and function in living things.
D. A cell is the basic unit of structure and function of all organisms
ANSWER
The correct option is D.
The cell theory is one of the major theories in biology and it states the facts about living cells. The theory states that, the cell is the most basic unit of all organisms and all living organisms are made up of one or more cells. The organisms that are made up of only one cell are described as unicellular while those that possess many cells are described as multi cellular. The theory also states that all cells come from pre-existing cells.
the correct answer is d
Answer: A. His heart beating more quickly.
Explanation:
The physical activity like running increase the rate of heart beat and blood circulation in the body due to muscular activity. During running the body experiences the depletion of oxygen. Oxygen becomes the main requirement for cellular respiration during running. To meet the requirement of oxygen the heart pumps the blood faster so that the requirement in each cell get fulfilled through rapid blood circulation.
On the basis of the above explanation, A. His heart beating more quickly. is the correct option.
