Answer:
Organism.
Explanation:
The cell is the smallest form of life. Cells work together to form tissues, tissues work together to form organs, and organs work together to create an organ system, and organ systems work together to create organisms. I believe "organism" includes all of these other levels.
<span>The ecological approach emerged as a reaction to the lab approach, which was considered sanitized and perhaps too controlled. What can happen in a lab cannot necessarily happen outside and vice versa.</span>
There were multiple theories of evolution prior to Charles Darwin's theory of evolution, some being from the antiquity, some just 300-200 years old.
One of the theories of evolution was the theory of hybrids. This theory was proposed by the great natural scientist Carl Linnaeus in 1744.
His theory was that initially God created small number of species, and placed those species on an isolated island. Over time, the created species started to breed between each other. That created numerous different hybrid offspring. These hybrids were actually new species, created by the breeding between the different species, and over time they developed into the numerous species we now of.
Answer:
Stage REM Sleep
Explanation:
According to the AASM (American Association for Sleep Medicine), the sleep has five stages. The first is the stage of wakefulness when you are starting to feel drowsy. Then the stage N1 is the transition into sleep: the breath becomes shallow, and the body doesn't move or just a little. In stage N2 the physiological function of the body start to decrease and is more difficult to wake up than the stage before. The next stage is the N3, which is the stage when is more difficult to wake up from all stages because is the deepest sleep, and in this stage, the movement of the eyes stops. The last stage is REM,(rapid eye movements), in this stage the brain is more active but the body is paralyzed.
