living organisms‚ the solvent (water) would have net movement across a selective permeable membrane. Osmosis only occurs when a membrane such as that of a cell is permeable to water molecules but not to specific solutes (Tortora & Derrickson 2014). Certain simple molecules such as oxygen‚ water and carbon dioxide can travel across the cell membrane by osmosis‚ a passive process similar to other forms of diffusion (Hill 2007). Not merely is it vital to several processes in living organisms‚ it also

A planarian is free-living flatworm that lives in fresh water. Planarians are organisms that live in freshwater. Planarians are part of the metazoan phylum. Animals in the metazoan like jellyfish have the ability to regenerate (Raymond 511-512). Planarians are closely related to animals like jellyfish and starfish. These animals shared the same special ability to regenerate; starfish are able to regenerate their arm when it is cut off. Jellyfish are able to regenerate their stinger when cut off (Li

All organisms must have adaptations to survive. The adaptations that organisms develop help them to survive in their environments and then are passed down through reproduction. The genes are passed to future generations and adaptations continue to occur over long periods of time. Nature Works tells us‚” animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.” There are three types of adaptations that can occur: morphological

Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit from the metabolism of other animals and plants. 2.2 Identify

Genetically Modified Organism (GMO) is one of the most important issues from around the world. GMOs are special organisms in which the genetic material has been altered for improvement productivity and product quality. GMOs have raised awareness about their products and their benefits to the world‚ such as‚ they are resistant to disease‚ help humans suffering from famine‚ produce greater yields and improve the nutrition of foods. Having foods is very important to human life to maintain good health

The cell is the basic unit of all life. All living things-- tigers‚ trees‚ elephants‚ and men-- are made up of cells. A cell is alive-- as alive as you are. It breathes‚ takes in food‚ and gets rid of waste. It grows and reproduces‚ or creates one of its own kind. (Garrod 36) Most cells reproduce by dividing‚ so that there are two cells where there once was one. (Akkas 78) Every living thing is made up of one or more cells‚ and each of these cells was produced by an already existing cell. New cells

Relationship between organisms and environment Mai Po Nature Reserve is an internationally significant wetland which is actually a flat shallow estuary‚ at the mouth of Sham Chun River‚Shan Pui River and Tin Shui Wai Nullah. Its 380 hectare area with diverse habitats provides a conservation area for mammals‚ insects‚ amphibians‚ reptiles and over 380 species of birds‚ some of which are highly endangered. During the field trip‚ we visited five different habitats‚ including fishponds‚ mangroves

No‚ I would not have my baby genetically altered. Even though genetic altering can prevent diseases and get rid of them; however humanity would be vastly different. If genetic altering was allowed then no one)would have diseases anymore or reduced there would be no point for professions such as doctors‚ nurses and all these diseases can be cured with one button.. Those professions would be left with unemployment which can cause another depression as people would be left without work or have to

Negative feedback in living organisms Negative feedback is a principle which is used by the body in order to return systems to its normal level; it does this by turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal environment. There are a number of different examples of negative feedback such as thermoregulation‚ regulation of blood glucose and the regulation of water potential. The control of the heartbeat can also use
