Answer:
pH meter and pH paper.
Explanation:
There are a few other ways that are commonly used, including titration, but most are tedious and require detailed hands-on work. A pH meter is normally assisted by the use of a computer or a digital user interface. The use of pH paper can be likened to the use of a Galileo thermometer.
All of the above points are valid for fossils' contributions in understanding the process of evolution. They allow us to study the ancestry, we can see the homologous organs or structures, if fossils are well-preserved; different fossils can lead us to follow the cycles of the changes that occurred during macroevolutions, and fossils can be used to study different populations which had different body structures for surviving in different environmental conditions.
Greater body size and facial gracility documented in Homo erectus are likely related to changes in tool technology and increasing access to meat and other proteins. Homo erectus walked just like a modern human, with traits like double arches and adducted big toe, they had a cranial capacity range from 650 cc to 1,200 cc.
Tropical Rainforest- >250 cm precipitation; 25c
Taiga- 101 cm precipitation - rain and snow; 15c
Tundra- no more than 25 cm precipitation in wettest month; <10c
Desert- <25 cm precipitation; 25c
These are the answers that were correct when i took this test. Hope this helps
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.
