<span>When the lid for a vat of wine is slightly open, the yeast inside can continue to perform alcoholic fermentation because the carbon dioxide produced by the yeast during fermentation will act as a blanket over the wine.  Nevertheless, the air around the fermenter must be still and enough carbon dioxide should be produced to continue alcoholic fermentation. However, at some point, carbon dioxide will fall and can no longer protect the wine. This is the right time to get your wine covered before it will be vulnerable to undesirable microorganisms. </span>

Therefore, open fermentation is good in the early stages of fermentation because yeast need oxygen to synthesize sterols and assimilate fatty acids to ensure the nutrients it needs to multiply and ferment the 70% of the sugar from the fruit. Furthermore, the yeast is responsible in decomposing sugar from the grapes into alcohol and carbon dioxide.

A student's grade goes from a 95 to a 65 in 3 weeks. Calculate
steposvetlana [31]

-10grade/week

Explanation:

Given parameters:

Initial grade = 95grade

Final grade = 65grade

Time = 3weeks

Unknown parameter:

Rate of change of grade = ?

Solution:

Rate is defined as the change of a quantity with time.

 Rate of change of grade  = \frac{Final grade - Initial grade}{Time}

Rate of change of grade  = \frac{65 - 95}{3} = \frac{-30}{3}

Rate of change of grade = -10grade/week

The rate of change of the student's grade is -10grade/week. It implies that the grade of the student reduces by 10unit per week.

Sladkaya [172]

Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)

Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to

contribute… then the rest works out as follows:

b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett

squares.

Baby 1 must belong to the Smiths, because they are the only ones with the possibility of EACH

having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore

only has the dominant A and dominant B alleles – no recessive allele possible.
