Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation.
used to separate the reactants from the products - it is pronounced "yields" or "produces" when the equation is read
Answer:
a. He is missing a control group of mice that did not receive the new antibiotic.
Explanation:
In any experiment especially experiments testing effectiveness of a drug, there should be a control group.
The importance of a control group is to minimize the effects of other variables other than the independent variable hence increasing reliability of the results.
in this case, a group of mice that did not receive the new antibiotic would have served as the control group.
Answer: The expected ratio would be 1:2:1.
Explanation: In a dihybrid cross, an organism with two different characteristics crosses with another organism with other two different characteristics. In this question, for example, the doubly heterozygous agouti mouse is represented by AaBb and the doubly homozygous recessive white mouse is aabb. So crossing them, we'll have
ab
AB AaBb (agouti)
Ab Aabb (black fur)
aB aaBb (albino)
ab aabb (albino)
Analising the table, there is 1 in 4 chances of a agouti; 1 in 4 chances of a black fur and 1 in 2 chances of an albino, therefore, the ratio is 1:2:1.
