Mitochondrial DNA is used to follow maternal inheritance and sequences on the Y chromosome is used to follow paternal inheritance. Why is it not practical to analyze paternal inheritance in this class?

Basically , male sex  cells  are  determined by the XY combination; heterosomes, (while the female sex cells by the XX). Since  it is the Y chromosomes present in  the father only that determines the  male sex of the child and therefore the proof of paternal inheritance ' the women in the class will not be able to participate in the inheritance analysis.Due to  lack  of  the Y -chromosomes.

Explanation:

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy

did you mean: energy is defined ashyperactivitya caloric measurementthe ability to move matterthe ability to think and analyze this form of energy is called "energy in motion" or "energy of moving matter"potential energy kinetic energy electrical energy1 ptlights on a stage can be examples of all of the following forms of energy exceptelectrical energylight energythermal energysound energywhen one type of energy changes to another this is called energy energy is stored based on their position or shape this is called energy.kinetic potential sound electromagnetic
