what is Symbiosis ???

s close and often long-term interactions between different biological species In 1877 Bennett used the word symbiosis (which previously had been used of people living together in community) to describe the mutualistic relationship in lichens. In 1879 by the german mycologist  anton de bary, defined it as "the living together of unlike organisms.

ome symbiotic relationships are obligate, meaning that both symbionts entirely depend on each other for survival. For example, many linchens  consist of fungal and photosynthetic symbionts that cannot live on their own.

  Others are facultative, meaning that they can but do not have to live with the other organism.

Symbiotic relationships include those associations in which one organism lives on another ,or where one partner lives inside the other endosymbiosis, such as lactobacilli and other bacteria in humans or zooxanthelles  in corals

  

Mutualism is any relationship between individuals of different species where both individuals derive a benefit. Generally, only lifelong interactions involving close physical and biochemicalbiologists  restrict the definition of symbiosis to close mutualist relationships. contact can properly be considered symbiotic. Mutualistic relationships may be either obligate for both species, obligate for one but facultative for the other, or facultative for both. Many

Commensalism describes a relationship between two living organisms where one benefits and the other is not significantly harmed or helped. It is derived from the English word  commensal used of human social interaction . The word derives from the medieval Latin word, formed from com- and mensa, meaning "sharing a table".mutualism

Amensalism

Amensalism is the type of symbiotic relationship that exists where one species is inhibited or completely obliterated and one is unaffected. This type of symbiosis is relatively uncommon in rudimentary reference texts, but is omnipresent in the natural world. An example is a sapling growing under the shadow of a mature tree. The mature tree can begin to rob the sapling of necessary sunlight and, if the mature tree is very large, it can take up rainwater and deplete soil nutrients

A typical example of symbiosis of "behavior" is the relationship between sea anemone and the hermit crab, crab "offers" shift anemone and it offers protection with its poisonous tentacles. Another example is that of Luther goby, a fish and blind shrimp. The shrimp digs a burrow with its strong legs and allows the fish the deal too. Instead, it acts as a seeing-eye, leading the shrimp in search of food. Shrimp with their antennae touching the fish's tail and it moves when it senses danger: in this case, the two retire to the den. It is also important as the mycorrhizal symbiotic association.

Today, MSF provides aid in nearly 60 countries to people whose survival is threatened by violence, neglect, or catastrophe, primarily due to armed conflict, epidemics, malnutrition,exclusion from helt care , or natural disasters. MSF provides independent, impartial assistance to those most in need. MSF reserves the right to speak out to bring attention to neglected crises, to challenge inadequacies or abuse of the aid system, and to advocate for improved medical treatments and protocols.
In 1999, MSF received the Nobel Peace Prize.
MSF is neutral. The organization does not take sides in armed conflicts, provides care on the basis of need alone, and pushes for increased independent access to victims of conflict as required under international humanitarian law.
MSF's principles of action are described in the organization's 1971 founding charter, which established a framework for its activities.

Techiques and tools for soap carving

What You’ll Need to Begin
Soap carving can be simple and inexpensive. You’ll need:
• A large bar of Ivory soap – Ivory's shape and texture are ideal for carving
• A paring knife
• 1-2 orangewood sticks used for manicures
• Pencil and paper for sketching
• Optional – Large tray to hold soap chips from carving
Unwrap the soap and let it dry for a day. Scrape off the lettering and any raised edges before beginning.


1. Developing Your Design
Begin with a simple design. Start with solid, basic shapes with simple cuts or extensions. Sketch your idea on paper first or try one of these sample patterns.


2. From Design to Soap Carving
• If you have a clear mental picture of your idea or have carved before, you can begin by carving directly on the soap.
• Or, you can use the orangewood stick to outline a rough sketch on each surface before you carve.


3. Begin with Rough Cuts
The actual carvings begin with rough cuts that remove the large parts of the soap not necessary for your design.
• Place the soap on the table or tray.
4. Adding the Details
• After the first cuts, you may find it more comfortable to use the knife as if peeling a potato.




5. Polishing
• Allow your sculpture to dry for a day or two.
• Then, rub it with a soft paper napkin, being careful not to break off corners or high points
