The correct answer is - Since 2000, more people are living with HIV, but fewer people are dying from AIDS.
Since the year 2000, the number of people that are living with HIV has been steadily increasing, though it has to be noted that the rise has been gradually slowing down. On the other hand, despite having more living with HIV, the deaths by AIDS have reduced gradually.
The main reason for the increase of people living with HIV is simply that there's more and more people in the world that can contact physically much more easily, so the disease can be transferred much more easily over larger distances. On the other hand, less and less people are dying from AIDS, and the reason for that is the discovering of the disease in its early stage, as well as the development of the medicine and keeping a certain routine in the lifestyle that is healthy.
D) Lagging strand is composed of Okazaki fragments
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.
The organism (Living thing), utilizes energy, can detect changes in the environment it is in, and can rearrange and synthesize chemical compounds.
Some things to remember, Living organisms need to be able to reproduce, obtain energy, usually by eating food in order to work. They need the ability to maintain structure, a body. They need to be able to react to a change, whether it be external or internal. The organism must be able to dispose of waste. Needs the ability to grow and develop. Must be able to move. and finally death. <span />
