Answer: The correct option is B) Symbiosis.

Symbiosis can be defined as a long term and a close biological interaction or relationship between two species, which involves the exchange of energy or food between them.

Niche is defined as the the position or ecological role played by an organism in a community of plants and animals.  It is determined by a set of environmental conditions, resources, and interactions it require.

On the other hand, Competition ( organisms compete for same environmental resources) and predation ( one population becomes the food resource for another population) are the other forms biological interactions.

Kira is a hemophiliac. This means that she does not produce clotting factors. What aspect of the clotting process should she be
meriva
A hemopheliac is someone with a bleeding disorder resulting from any missing clotting factors in their blood. Vasoconstriction isn't generally the problem in hemophiliacs, nor is it the destruction of pathogens. If fibrin threads are not present to help form the platelet plug, then excessive bleeding occurs. Fibrin is one clotting factor that a hemophiliac may be missing which is then causing the disorder.

Compare the modern Cell Theory to the original Cell Theory
CaHeK987 [17]
The statements of the old cell theory are:
1. All organisms are composed of cells
2. The cell is the basic unit of life
3. Cells are produced from existing cells

The modern cell theory's statements are:
1. The cell contains hereditary information which is passed to daughter cells
2. All cells are basically the same in composition and activity
3. All basic functions occur in cells
4. Cell activities depend on intracellular structures

As is visible from the statements, the old cell theory was not as detailed and lacked the understanding of the function, structure and behavior of cells that the current theory possesses. This difference has come about after years of research, through which scientists understood the functions of cells and elaborated on the theory's statements.
