The more air is in the jar, the longer the candle will be able to burn. So the candle in jar 3 probably burned for 4 minutes.
The candle in jar 4 would be able to burn much longer then the others, because it has no lid so air can come through and keep the candle burning.
Answer:
Varicella-zoster virus
Explanation:
Varicella-zoster virus (VZV) is a virus with double-stranded DNA as its genome. It is a member of the family Herpesviridae. The virus causes chickenpox in children. It is mostly present in the latent form after the disease subsides and the same virus can cause shingles in adults under specific conditions. Therefore, shingles is also called a reactivated form of chickenpox caused by the latent varicella-zoster virus. The virus has an incubation period of 10 to 23 days and causes the formation of pus-filled small vesicles on the face or upper trunk.
It has been estimated that ‘slash and burn’ agriculture is
used by up to 500 million people worldwide. The term describes the practice of
cutting and/or burning of natural vegetation for conversion into agricultural
fields. Besides the disastrous implications for forest ecosystems, the practice
can impact the atmosphere in two main ways if burning is implemented. Firstly
by causing air pollution from the smoke, and secondly by increasing carbon
dioxide in the atmosphere, which is a greenhouse gas and a driver of climate
change. Living trees also remove carbon dioxide from the atmosphere during
photosynthesis, and the process of ‘slash and burn’ effectively removes their
carbon capturing contributions to ameliorating climate change.
Organisms are made up of a bunch of cells. Billions of cells coming together make up an organism.
There will always be one stronger species that take over, which is what evolution has taught us.
