Joseph Priestley is an 18th century natural philosopher who is famous in his experiments in electricity, air, optics and soda water. His works are qualitative rather than quantitative because he does not concern himself with theories but practical applications.
His experiment in electricity through replication of other experiments lead to the publication of his book known as History of Electricity. He observed that electricity conducts through certain materials like coal and that electricity flow from conductors to non-conductors.With this experiments he concluded that conductivity is related to chemical property.
Another experiment that lead to a famous discovery is placing a mice in closed container with mercuric oxide. He concluded that the mice survived sometime because of common air-oxygen. He then relate oxygen in respiration and its use in the blood.
cell :- cell is the basic structural and functional unit of life.
Atom :- everything in the universe is made up of atom.
Answer:
The population of native species got decreased.
Explanation:
Rabbits are not native species to Australia, they were introduced as a food for dogs and to be fed to poultry, however, the appropriate climate of Australia had resulted in the overpopulation of rabbits. This had further affected the native ecosystem that had resulted in the loss of vegetation, crops, and native species found in Australia.
The rabbits indirectly assisted in sustaining the populations of fox and Ferrel cats that further resulted in enhanced predation of native species, which eventually resulted in their extinction. Thus, the introduction of rabbits resulted in the destruction of the native ecosystem.
Answer:
Sister chromatids separate from each other during anaphase of mitosis and the anaphase II of meiosis II. During the anaphase stage of mitosis these chromatids separate and one chromatid goes into each daughter cell. During cell division they are separated from each other and each daughter cell receives one copy of the chromosome.
Explanation:
I would go with D as it is closest to correct. Every part of the surface of the Earth is a tectonic plate though. The plates vary in thickness, but all of the surface of the Earth is made up of tectonic plates, including the parts under the ocean. Technically, the Earth's landmass does not rest on the tectonic plates, it IS the tectonic plates, but it is the closest to correct here in my opinion.
