Pet Cloning

I would never clone a pet!! I love my pets to death but do not understand why something like this is necessary. I think the price people pay is utterly ridiculous and I do not believe that the cloned pet can be the exact same as the pet that died. A pet's personality is developed through more than just its genes. Socialization plays a big role, just as it does in humans. I think by accepting cloning we are ultimately accepting changing nature. There is a circle of life for each and every living organism and I do not believe we should alter or change that cycle. I do think the scientific advancement to be able to clone organisms is amazing and something to be proud of, but that does not mean I think it is something that should become a part of everyday life. Cloning would have the possibility of altering the perception of death by making people believe they can just 'make another one'. Death is a way of life and society needs to accept and face that fact. Going back to specifically cloning pets, the interaction between owner and pet is what is important, not the coat color, size, or even personality. People need to cherish the time they have with an animal because the interaction will be different if everyone thinks they can simply have another.

Genetic Problems

Okay... so I have slowly been plugging away at these questions. I've looked at the questions and answers, (or hints), that others have posted which has actually helped me a lot. However, one I cannot seem to fiure out is number 6. I'm pretty sure I am over thinking it, but I also could be going about it completly wrong! I get frustrated with so many componets and my thinking shuts down. So if anyone has any helpful hints concerning problem number 6 I would greatly appreciate it! Thank you very much ahead of time!

Anaerobic Respiration

Humans could not function using just anaerobic cellular respiration but there are times when our body relies on anaerobic cellular respiration to function. Our body switches to using anaerobic cellular respiration when your muscles expend ATP at a rate faster than your bloodstream’s delivery of oxygen from your lungs to your muscles. However, the process of fermentation relies on glycolysis without oxygen but only produces two ATP molecules for each glucose molecule broken down. Our body is much for efficient when our cells are using cellular respiration to gather food energy.
Warm-blooded creatures, like mammals and birds, try to keep the inside of their bodies at a constant temperature. They do this by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment. To generate heat, warm-blooded animals convert the food that they eat into energy. They have to eat a lot of food, compared with cold-blooded animals, to maintain a constant body temperature. Only a small amount of the food that a warm-blooded animal eats is converted into body mass. The rest is used to fuel a constant body temperature. Cold-blooded creatures take on the temperature of their surroundings. They are hot when their environment is hot and cold when their environment is cold. In hot environments, cold-blooded animals can have blood that is much warmer than warm-blooded animals. Cold-blooded animals are much more active in warm environments and are very sluggish in cold environments. This is because their muscle activity depends on chemical reactions which run quickly when it is hot and slowly when it is cold. A cold-blooded animal can convert much more of its food into body mass compared with a warm-blooded animal.
