The process of osmosis and its importance to living organisms Osmosis is the process by which there is a net movement of water through a semi permeable membrane from an area of high water potential to an area of low water potential. Within a cell‚ osmosis has the following effect. If the water potential of the cell is lower than that around the cell water will move across a concentration gradient into the cell. If this is the case‚ the increase in water in the cell‚ may cause the cell to swell

Although computer viruses and biological viruses are not related in any way‚ they are very similar in many aspects. Both viruses need a host to replicate for a means of survival. Similarly‚ both enter their hosts passively. Biological hosts are infected by breathing‚ ingestion‚ or direct contact while infected software‚ email attachments and transfers infect the cyber host. Another notable similarity is the fact that both computer and biological viruses need the proper host as well as software and

It results in the separation of a single cell into two. Transformation: genetic alteration

DOLP- Fungi General Structure and Function: For many years‚ fungi were classified into the plantae kingdom because the two kingdoms seemed to be alike; but now‚ we know that they are all too different. In fact‚ the fungi kingdom is more closely related to the animalia kingdom. Some of the only notable similarities between the fungi and plantae kingdoms are that they are both made of eukaryotic cells‚ both immobile‚ both contain cell walls (although made of different material)‚ and both evolved

Ever wonder how evolution comes to be? How some species win and others lose? Evolution has many different ways of making organisms all better‚ faster‚ and more adept to live. Four big categories of the mechanisms of evolution are natural selection‚ gene flow‚ genetic drift‚ and mutations. The majority of the time‚ nature goes by a trial and error system that can take up many centuries to come up with a change that is beneficial. Natural selection is the process in which nature removes its mistakes

Lupita Garica Mr. Zarate 8/29/14 Period 7 Are Viruses Alive? For many years there have been numerous controversies over whether a virus should be classified as living or nonliving. It is believed that viruses are considered nonliving because they lack a substantial amount of qualities to be classified a form of life and they are incapable of carrying out all life processes. For example‚ some characteristics that would justify a virus being nonliving would be that they are acellular: they are not

they say society is like a biological organism. Parsons found three similarities between society and an organism. System organisms such as the human body and society are both self-regulating and inter-related‚ independent parts fit together in fixed ways. In the body these are organs; in society they are institutions‚ such as family and education. Both organisms have system needs for example an organism needs nutrition without which it would die. Social systems have basic needs for example members of

Bacteria are the most numerous type of microorganism found in the rhizosphere of the soil. They produce secondary metabolites which are capable of producing antibiotic which eventually inhibit or kill bacteria. The rhizosphere region of the soil is a highly favorable habitat for the proliferation‚ activity and metabolism of numerous microorganisms. The magnitude of this area depends on the plant and the size of the roots that the plant possesses. Bacteria are among the microorganisms living in the

Unicellular organism From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search "Single-celled" redirects here. For prison cell assignment‚ see Single-celling. Valonia ventricosa is among the largest unicellular species. A unicellular organism‚ also known as a single-celled organism‚ is an organism that consists of only one cell‚ unlike a multicellular organism that consists of multiple cells. Historically the simple single celled organisms have sometimes been referred to as monads
