Over the past few centuries scientists have been trying to answer the question: what was the origin of life? There have been a number of scientists who have produces a number of plausible theories. The currently most excepted theory is Oparin’s theory‚ which states that the "origin of life on Earth was in nonliving chemical substances which spontaneously formed in Earth’s early atmosphere and combined to make more complex chemicals until living cells were formed. " This maybe a possibility because

I. Title Laboratory 11. Animal Behavior II. Purpose The purpose of the animal behavior lab was to understand the concept of distributing organisms in a resource gradient. This lab was also made to help us differentiate between kinesis and taxis. After completing the animal behavior lab‚ we should be able to describe aspects of animal behavior as far as its orientation behavior‚ agonistic behavior‚ dominance display‚ and the way it mates or who it chooses to mate with. We should also understand

Leeuwenhoek‚ Robert Hooke‚ Matthias Schleiden‚ Theodore Schwann‚ and Rudolf Virchow‚ refers to the idea that cells are the basic unit of structure in every living organism. The theory justifies three principles: all living organisms are composed of one or more cells; the cell is the most basic unit of structure‚ function‚ and organization in all organisms; and all cells come from pre-existing‚ living cells. The formation of the cell theory started in the early 1600s‚ in the Netherlands‚ where the spectacle

The interaction within the assorted components in an area brings about an ecological balance. Studies have found that ecological balance refers to the dynamic state of the stability in a community of organisms within which ecosystem diverseness‚ species‚ and genetics remain stable‚ based on gradual changes through the natural succession
