<h2>Jean Baptiste Lamarck</h2>
Explanation:
Jean Baptiste Lamarck (1744-1829) was an important French naturalist. He was one of the first scientists to propose that species change over time.
Jean Baptiste Lamarck published his theory of evolution in the book <em>Philosophie zoologique </em>called the theory of use and disuse or the inheritance of acquired characteristic. According to this theory, ecological conditions in which an organism lives cause it to have certain needs. These needs are met by modification of old organs or by production of new rudimentary organs.The continuous use of the rudimentary structures allows them to increase in size and disuse causes that organ to degenerate. These changes become fix and become inheritable.
Answer:
Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.
Explanation:
A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.
If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.
To solve this question you need to know the specific heat of the object, which is water. The specific heat of water is 1 calorie/gram °C = 4.2<span>joule/gram °C. The energy needed would be:
Q= c*</span>m*ΔT
Q= 1 calorie/gram °C * 250 g * (85-25°C )
Q= 15000 calorie= 63000J
