Answer:
An identical setup but replacing the enzyme with an equal volume of water
Explanation:
When carrying out any experiment, it is important to set out a control in order to increase the reliability of the data and results.
The control minimizes the effects of variables other than the independent variable.
In the above experiment, starch has to be eliminated and replaced with water. Water does not have starch hence the digestive enzyme being tested will not have any effects making the data and results from the experimental group reliable.
Answer:
1/2
Explanation:
Genotype of the heterozygous mother= X^cX
Genotype of color-blind father= X^cY
A cross between heterozygous mother and color blind father would give progeny in following phenotype ratio=
1 colorblind daughter: 1 colorblind son: 1 carrier but normal daughter: 1 normal son.
Therefore, this couple has 1/2 probability of getting a colorblind daughter is 1/2

<span>Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.</span>
