Answer: Sunlight entering the water may travel about 1,000 meters (3,280 feet) into the ocean under the right conditions, but there is rarely any significant light beyond 200 meters (656 feet).
The ocean is divided into three zones based on depth and light level. The upper 200 meters (656 feet) of the ocean is called the euphotic, or "sunlight," zone. This zone contains the vast majority of commercial fisheries and is home to many protected marine mammals and sea turtles.
Only a small amount of light penetrates beyond this depth.
The zone between 200 meters (656 feet) and 1,000 meters (3,280 feet) is usually referred to as the “twilight” zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases. Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible.
The aphotic, or “midnight,” zone exists in depths below 1,000 meters (3,280 feet). Sunlight does not penetrate to these depths and the zone is bathed in darkness.
‘Photic’ is a derivative of ‘photon,’ the word for a particle of light.
Answer:
In a pedigree chart, the line which is horizontal shows the parents which mated and produced the children which are represented in the vertical lines below them.
A pedigree chart can be described as a diagram which illustrated the sequence of ancestors of an individual. Often, a pedigree chart is used to look for genetic traits or genetic disorders which might run in the family history. Pedigree charts are important for understanding the probabilities of the offsprings in which a genetic disorder might occur due to family history.
Answer:
The way in which we produce our offspring, gametic meiosis, is very different than how bacteria and Bacillus cereus reproduce. In fact it is much simpler. The male doesn't have to buy the female anything, there is no commitment between bacteria, and it's just plain simple. Well, to start off there is no male or female in bacteria, and do not even need a partner to reproduce!
Often Bacillus cereus undergoes reproduction by the means of asexual reproduction (offspring are produced from a single parent; no this does not marital status), more specifically binary fission. Binary fission is the asexual reproduction method used by all prokaryotes, it occurs when a single parent cell undergoes mitosis and produces two equally sized daughter cells. Both daughter cells produced have the potential to grow to the size of the parent cell. The down side of binary fission is that both daughter cells are genetically identical.
