What do you think about the corona virus?
do you think it will ever get better?
do you think it is the beginning of the end of the world?

Well about COVID, it is more deadlier and infectious than SARs. It's outbreak was the worst thing to happen in the first place. But in China, people are always fascinated by new things and food. They have many categories, especially in food. The main outbreak happened in Wuhan where people tend to eat Bats, meats etc. The spreading of this virus was mainly beacuse of unhygenic meat slaughtering system that led the COVID reach Humans through meat. Things are slowing down and China has saved it's people through Isolation, protection, medications etc. Now the death rate in China is decling(which is a good thing). I think no. There won't be an apocalyptic situation. Almost all the countries have taken safety measures to stop the infections. Even free gas mask are given to people of most of the countries. Those who resist for check up are taken forcefully to the ward. The world will face virus or disease outbreak which at some point will be cured like COVID(it's not cured but research is still on. And Doctors often say that PREVENTION IS THE BEST MEDICENE).

i'd say that the moon rock is about 2.2 billion years old.

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
