Oxygen has a partial negative charge, whereas hydrogen had a partial positive charge. 
This means that water molecules are polar and can be used to dissolve a lot of chemicals, that's why water is such a popular solvent.

They are all tetrapoda.
Tetrapods are animals (group of vertebrates) with four limbs including amphibians (frogs), reptiles (caimans), birds (parrots) and mammals (hares, humans). Even though the subgroups within Tetrapods differ a lot, they all have various adaptations of the skeleton and muscles that enable them movement on land, adaptations of cranium (for head stability), tissues that reduce water loss (because of living outside the water)…Except amphibians all other tetrapoda are amniotes (have amnion layer around embryo)
 
        
             
        
        
        
<u>Answer:</u>
The invention of agriculture, advances in medical technology that have greatly reduced the human death rate and he rapid increase in the uses of fossil fuels, fertilizers, metal ores, and other resources.
Option: (A), (C) and (D)
<u>Explanation:</u>
- The Great Acceleration refers to the humanity’s impact upon the Earth’s geology and its ecosystems caused by continual and surge in growth of human activity. 
- It was first recorded in mid-20th century and is continuing to this day. The 'invention of agriculture', advancement in medical technology which reduced the death rate, rapid increase in use of 'fossil fuels', 'fertilizers' and other resources contributed to global changes. 
- Agriculture allowed us to produce more food and population increased rapidly. 
- Fossil fuels created a surge in production of Green House Gases and global temperature began to rise.
