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.
b. interbreed
c. move the same way
d.eat the same prey
B. Interbreed is the correct answer.
In a food web, each step in the transfer of energy and matter is referred to as a trophic level. These steps provide an illustration of energy flow within an ecosystem, with examples being producers, consumers, and higher-level consumers. The transfer of energy - although more complex - is more accurately depicted in a food web than in a food chain.
The term for each step in the transfer of energy and matter within a food web is known as a trophic level. These are the different steps in a food web or chain at which the transfer of energy occurs. An example of these levels can include producers, primary consumers, and higher-level consumers, each playing specific roles in the overall energy flow.
A food chain is a linear system that offers a simplified view of energy transfer within an ecosystem, while a food web offers a more complex and holistic view of the multiple trophic interactions and energy transfers within an ecosystem.
It is important to mention that energy transfer efficiency influences the structure and dynamics of ecosystems. This is due to the fact that with each energy transfer, some energy is lost, often in the form of heat. This limits the length of food chains within a food web.

TRUE
Pollution can be defined as the introduction of biological matter, particulate and chemicals that are harmful to humans, plants and animals. pollution can also cause damage to natural environment. However, animal digestion can cause natural air pollution by releasing methane which is a greenhouse gas.
Answer: True
Explanation: Human beings pollute the air by undergoing several activities like burning of fossil fuels, combustion of the fuels by the automobiles, emission of hazardous gases from industrial and agricultural wastes. But human beings are not only responsible for this pollution but animals like cattles (cow, baffallo) excreate a large amount of dung which is a source of greenhouse polluting gas called as methane.
b. flatworms.
c. cnidarians.
d. roundworms.
