Louis Pasteur’s experiments has taken a leap on cell biology. He was able to contribute to the concept of cell theory which suggests that cells came from pre-existing cells, cells are the fundamental unit of life and that all life have cells.
Highlighting on pre-existing cells, early before the experiments of Pasteur, there was the theory of spontaneous generation. This theory claims that organisms came from nonliving objects which is now, truly misleading and wrong.
The answer should be d, they are in domain eukarya so their cells are eukaryotic.
Answer:
Moreover, the way that this works is that convection currents in the mantle causes tectonic plates to move when material near the Earth's core rises, and colder mantle rock sinks. Hot magma wells up at the ridges, forming new ocean crust and shoving the plates apart.
Explanation:
The oceans on earth act as carbon sinks
the combustion of fossil fuels
atmospheric carbon dioxide is continuosly exchanged
vegetation and soil take in more co2 than they release
Answer:
Nitrogen and phosphorus pollution which causes the increase in population of phytoplanktons lead to the process called euthrophication.
Explanation:
Eutrophication occurs when there is excessive level of phosphorus and nitrogen in the water that leads to the increase in population of phytoplanktons or algal blooms. Algal blooms has a negative effect to the quality of water for it creates an environment suited for the growth of bacteria and thereby decreasing the supply of oxygen in water. This leads to death of fishes and aquatic life.
