The complete separation of a bone from its normal position in a joint is known as a dislocation.

A dislocation is a painful condition in which there is an injury to a joint (an area where two or more bones are joined together). The ends of the bones are unexpectedly forced from their normal position which temporarily deforms and makes the joint immovable. Dislocation usually occurs in shoulders and fingers. Other body parts it can occur include hips and elbows. Symptoms of a dislocation include visibly deformed joint, swollen joint and intense pain around the affected joint area.

Match each type of cell junction with its description.
Ne4ueva [31]

Answer:

Tight junctions - prevent liquid from seeping between cells

Desmosomes - act as rivets to hold adjacent cells together when epithelial tissue moves

Gap junctions - allow movement of cytosol, ions, and small molecules between animal cells

Plasmodesmata - openings through the cell walls of plant cells that allow adjacent cells to share materials

Explanation:

1) Tight junctions are one of the cell junctions found in animal cells. Tight junctions function to prevent the flow of liquid materials between cells.

2) Desmosomes are another type of cell junctions whose function is to form a connection between two adjacent cells. The structure formed by this connection confers strength upon the tissues involved.

3) Gap junctions are the most commonly found cell junctions found in animal cells that connects adjacent cells allowing the passage of cytosol, ions and other small molecules in them from one adjacent cell to another.

4) Plasmodesmata is a cell junction found in plant cells. They are small openings lying across the cell wall of plant cells whose function is to connect the cells and facilitate the movement of materials from one cell to another.

Genetic diversity is ultimately/mainly the result of _______________
RUDIKE [14]

Answer:

A. meiosis.

Explanation:

Meiosis is one of the two major types of cell divisions in living organisms. Meiosis is the process by which four daughter cells that are genetically different from the parent cell are produced. Meiotic process is carried out solely during sexual reproduction to yield gametes or sex cells.

The gametes have their chromosomal number reduced by half during the process. However, one immense importance of meiosis is that it PROMOTES GENETIC DIVERSITY. A process called crossing over, which is the exchange of chromosomal segment between non sister chromatids, makes this possible.

Because they play important roles in the environment, take the food chain for example. animals continuously convert energy all the way up until a human eats. also, decomposers are important too because the return nutrients to the ground, like mushroom, fungi, and bacteria
