5. A student adds a suspension of baker's yeast cells into bread dough. After this mixture is left in a large bowl undisturbed for several hours, the student returns to find that the bread dough has doubled in size. Which gas molecule is responsible for this increase in dough size?

Answers

Answer:

The gas molecules responsible for the increase in dough size are carbon dioxide.

Explanation:

Yeast feed of sugars by braking them into carbon dioxide, alcohol, other molecules, and energy. This process is known as fermentation. When fermentation occurs, carbon dioxide expands, helping the bread dough to increase. Yeast is also important to produce alcohol and gluten, both important to bake bread.
accumulation of carbon dioxide is responsible for the increase in dough size

What is a possible cost of habitat destruction?Non-sustainable energy
Fewer landfills
Less biodiversity
Fossil fuel decreases

Answers

A possible consequence of habitat destruction is less biodiversity. The variety of life forms that reside in a habitat are highly dependent upon that particular environment. Often, when a habitat is destroyed the life within is destroyed as well, or at the vary least has difficulty finding a new habitat and may have to adapt themselves in ways that make them similar to the life that already exists in the new habitat, leading to less biodiversity.

Habitat destruction leads to loss of biodiversity because many organism are killed in the process of habitat destruction.

An experiment is done on three tomato plants over a 50 day period to test the following hypothesis: If either fertilizer or compost is used on plants then a plant that gets fertilizer will affect the plant growth the most. The same amount of water and light were applied to each tomato plant. Pot A contained no fertilizer or compost, Pot B contained fertilizer and Pot C contained compost. Which is the independent variable? a. Time of experiment b. Amount of water c. Plant growth d. Amount of fertilizer

Answers

the correct answer is d. Amount of fertilizer. The independentvariable is the variable that is deliberately changed or manipulated in an experiment to see its effect on the dependent variable.

In this experiment, the independent variable is the amount of fertilizer or compost added to the tomato plants, as it is the variable being intentionally varied to test the hypothesis. Therefore, the correct answer is d. Amount of fertilizer. The dependent variable in this experiment is plantgrowth, which is the variable being measured to determine the effect of the independent variable. The other variables mentioned, time of experiment and amount of water, are likely held constant throughout the experiment as part of the experimental design, and therefore do not serve as independent variables.
