Hydrothermal Vents and its Organisms! A hydrothermal vent is a fissure in a planet’s surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places‚ areas where tectonic plates are moving apart‚ ocean basins‚ an hotspots Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Common land types include hot springs‚ fumaroles and geysers. Under the sea

1. Why is cell differentiation important in the formation of organ systems? - When a cell differentiates‚ it becomes more specialized and it may undertake major changes in its size‚ shape‚ metabolic activity‚ and overall function. Cellular differentiation is important and occurs so cells can specialize for distinct functions‚ such as an organ system‚ within an organism. All cells in the body‚ beginning with a zygote‚ contain the same DNA then go through cell growth and division‚ also called mitosis

systematic growing and harvesting of various organisms. Allele A variation of a gene’s nucleotide sequence (an alternative form of a gene). Allele Frequency The measure ofthe relative frequency of an allele at a genetic locusin a population; expressed as a proportion orpercentage. Analogous Structure A physical structure‚ present in multiple species‚that is similar in function but different in form and inheritance. Aquatic A term that describes an organism associated with a water environment. Atom

INTRODUCTION: These experiments helped us learn the factors that were involved in the growth of the bacteria that increased our study towards their genetic‚ physical and metabolic characteristics. We used Escherichia coli and Bacteriophage T7 to identify and analyze their identical life cycle and replication that was involved in their process of growth. As‚ growth for any bacteria means it multiplying by increasing in its size and quantity‚ which can easily be examined by measuring its cell mass

Preserve the Forests In agreement with Kim Stafford‚ who opposes the clear-cutting of old growth forests‚ I feel that it is necessary to preserve the profitable lumber in its natural state for future generations. Currently‚ the tons of lumber produced from the Pacific Northwest region of the United States are taken for granted‚ and most people do not realize that the forests will be destroyed within ten years at this rate of exploiting our natural resources. We must make loggers a profession

the issue of not legalizing the payment of donating organs. The National Kidney Foundation does not believe that the payment for organ donating will increase donations. The foundation wants to remain committed to helping people with donations. They believe that if it is legalized then disadvantaged citizens would take advantage of this opportunity that should only be done for the great feeling of it‚ and not the money. Sally Satel believes that organ trafficking should be stopped by legalizing some

What is a genetically modified organism? A genetically modified organism (GMO) is an organism whose genetic material has been altered using techniques in genetics generally known as recombinant DNA technology. Viruses‚ bacteria‚ fungi‚ plants‚ and animals are all examples of organisms that have been engineered so that they contain genes from at least on unrelated organism. To create a genetically modified organism a molecule from a different source are combined into another molecule to create

The uses of forests | | Forests and the many varying trees of which they are composed have‚ since the very earliest days played an important part in the life of mankind. It is because of this that men have realized their value and have taken steps to preserve them and to prevent their wanton and useless destruction.From the primitive days of the wigman‚ the house on stilts or the African but‚ wood has been the basic material used for men’s housing to provide shelter from the animals.

Everyday about twenty-two people die waiting for a life saving transplants‚ which doesn’t make sense then there are so many opportunities for them to be saved. The only thing keeping them from being able to live is that not enough people are registered organ donors. Ninety five percent of people agree that being an organ donor is the right thing to do but only about fifty two percent are actually registered donors. Becoming an organ and/or a tissue donor has no cost the the donor’s family or estate
