Yes. All animals require oxygen.
They both require mechanical and chemical digestion.
Yes, Tapeworms are gutless due to the fact that tapeworms don't require a digestive system as they reside within the digestive system of humans or animals.
Starch and cellulose require different digestive enzymes for the same reason that different locks require different keys. The specific shape, and distribution of electrical charge in any given molecule determines the specific enzyme that will be needed to digest it. Every chemical is different.
In some cases, yes. Muscular dystrophy can weaken the muscles required for breathing, leading to respiratory insufficiency. Ventilatory assistance devices may be necessary to help with breathing support in severe cases of muscular dystrophy.

You require cardiovascular endurance, speed, muscular endurance, co-ordination and body composition to be able to run.
Almost all sports need muscular strength of some type or form. For example even in running it is important to train the muscles of your legs. If you mean dense muscle, sports such as shot put and perhaps boxing are sports that require muscular strength.
activities that require good muscular endurance are activities that require you to work with muscle groups for a longer period of time. eg. swimming- good muscular endurance is needed so that you can maintain a good standard performance all the way throughout and so that your arm stroke does not get weaker/arms get tired. with good muscular endurance, your arms will not get tired as easily and you can keep up strong, fast strokes.
Some examples of muscular power activities include jumping, sprinting, medicine ball throws, plyometric exercises, and kettlebell swings. These activities involve explosive movements that require a rapid application of force.
Reflexes provide the body with a rapid mechanism for self-protection. Because they don't require thought, they are faster than voluntary muscular responses.
Muscular force is the force applied using parts of the body like arms or legs. It is force that results due to the action of muscles, and is a contact force, since there is a contact between the surfaces. Muscular force is needed whenever movement of the body occurs. Walking, lifting, getting up from a chair, crossing a leg, etc. all require muscular force.
