What do alcohol fermentation, acetyl coa formation, and the krebs cycle have in common?
a. all produce water.
b. all produce carbon dioxide.
c. all produce atp.
d. all produce alcohol.

Answer;

B. All produce carbon dioxide.

Explanation;

-Alcoholic fermentation is a process in which sugars such as glucose are converted into small amounts of energy in form of ATP, and producing ethanol and carbon dioxide.

-Acetyl CoA is produced through decarboxylation of pyruvate in the matrix of the mitochondria. This results to a molecule of Acetyl CoA and carbon dioxide.

-Kreb's cycle is the second phase of cellular respiration which involves the sequence of reactions by which most living cells generate energy.  The process takes place in the mitochondria, utilizing oxygen and producing carbon dioxide and water as waste products, and ADP is converted to energy-rich ATP.

-From these descriptions it is evident that the similarity among the following processes is that all produce carbon dioxide.

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
