The Scientific Method is a logical and rational order of steps by which scientists come to conclusions about the world around them. The Scientific Method helps to organize thoughts and procedures so that scientists can be confident in the answers they find. ... HYPOTHESIS is the answer you think you'll find.
The answer is B: bat wing, and tyrannosaurus arm. Hope this helps
Answer:
No, because someone with blood type O has the genotype OO because O is recessive. One parents would need one allele to be A and the other parent would need one allele to be B for the child to be AB. But the man does not have an A or B allele, so it is not possible for him to be the father of a child with blood type AB.
Experimental Setup In this section you describe how the experiment was done and summarize the data taken. One typically describes the instruments and detectors used in this section.
Answer:
A) effect of sugar on a metabolic activity of yeast
Explanation:
In this experiment, everything was kept the same except for adding sugar into one test tube and none on the other. The data that was recorded was the bubble formation. Bubble formation is an indicator for a chemical reaction and in this case it is the metabolic activity of the yeast.
Everything that is kept constant like the amount of yeast suspension, temperature and time it was placed in the warm water bath are what we call controlled variables. This is done to prevent any other variables from affecting what is being tested.
The amount of sugar is what is different and this is called the independent variable. This is what we are testing to see if it will have an effect.
Finally, bubble formation or metabolic activity is the dependent variable. This is what will be observed as a result of the changes in the independent variable.
