Answer:
2Major Structures and Functions of the Brain
Publication Details
Outside the specialized world of neuroanatomy and for most of the uses of daily life, the brain is more or less an abstract entity. We do not experience our brain as an assembly of physical structures (nor would we wish to, perhaps); if we envision it at all, we are likely to see it as a large, rounded walnut, grayish in color.
This schematic image refers mainly to the cerebral cortex, the outermost layer that overlies most of the other brain structures like a fantastically wrinkled tissue wrapped around an orange. The preponderance of the cerebral cortex (which, with its supporting structures, makes up approximately 80 percent of the brain's total volume) is actually a recent development in the course of evolution. The cortex contains the physical structures responsible for most of what we call ''brainwork": cognition, mental imagery, the highly sophisticated processing of visual information, and the ability to produce and understand language. But underneath this layer reside many other specialized structures that are essential for movement, consciousness, sexuality, the action of our five senses, and more—all equally valuable to human existence. Indeed, in strictly biological terms, these structures can claim priority over the cerebral cortex. In the growth of the individual embryo, as well as in evolutionary history, the brain develops roughly from the base of the skull up and out ward. The human brain actually has its beginnings, in the four-week-old embryo, as a simple series of bulges at one end of the neural tube.

What kingdom does what most likely belong in? We need some more information. :)
The answer. is c because the pine tree seeds will fall and create more over time
Most likely the source of the it and any other organism would be its parents. you see organism reproduce sexually or asexually. In asexual, the cell will just split into two when conditions are right like abundance of rescources, correct remperature etc. For sexual reproduction, it just has to have two organisms of opposite sexes
Answer:
Is the explanation of life in Earth.
Explanation:
At the begging in the era called Archean, 3500 millions of years ago, the first life forms or Earth started to appear, in seas, where there were nutrients, water, heat from sun, etc. Later on 2500 millions of years ago, the first stromatolites appeared, they were so important because were the first group of cyanobacteria together, they can start to produce a little bit more oxygen in water seas. In the precambrian era (600 millions of years ago), the bacteria evolve into a complex living things like worms, jellyfish, etc. to the cambrian period, they evolve in the first vertebrate animals. by the ordovician period (489 millions of years) the first plants started to appear in Earth, turning the atmosphere greener because of the photosynthesis that they made. and at that time also, the ocean seas started to separate the continents ( the supercontinent called Rhodinia). Later in Devonian period ( 418 millions ago) the first reptiles started to appear on earth, with this step the first animals appear to conquer the Earth. By evolution, these animals turned into different living things like birds and dinosaurs. It was until the Jurassic period (200 million of years) where the pangea split in different continents and it was the gold era of dinosaurs. Later until the Quaternary period (1.8 millions of years) humans we started to appear.
