<u>ANSWER:</u>
When a supergiant runs out of fuel, the object formed is either a black hole or a neutron star. 
<u>EXPLANATION:</u>
- Supergiant are very large stars in the galaxy that end their lives very quickly. 
- When a supergiant star loses its fuel, it blows itself by a supernove explosion. 
- When supernove explosion happens, the supernova outshines other stars in the galaxy and then slowly faded away leaving a dense object called black hole or neutron star. 
- This black hole or neutron star is surrounded by a mass of very hot gas and the elements of the supergiant star get scattered into the space.

Answer:
Skeletal muscle decomposes more slowly than internal organs and nerve tissue after death, but still more quickly than cartilage and bone.
Together, these factors make muscle tissue a good candidate for postmortem change study and well-suited for standard forensic lab examination.
 
        
             
        
        
        
Answer:A bat has a much more flexible wing structure. It is very much like a human arm and hand, except it has a thin membrane of skin (called the patagium) extending between the "hand" and the body, and between each finger bone. Bats can move the wing like a hand, essentially "swimming" through the air.
