*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
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.
Tight junctions prevent liquid seepage between cells, desmosomes hold cells together, and gap junctions allow movement between animal cells.

Answer:
Differentiated cells refer to the specialized cells in multicellular organisms modified to carry out a particular function, such as transporting a certain substance or executing a specific task, while undifferentiated cells refer to the stem cells capable of giving rise to indefinitely more cells of the same type,.
Answer:moutains
Explanation:when two sides of the earth push together it forms moutains
Answer:
Uplift is the process by which the earth's surface slowly rises either due to increasing upward force applied from below or decreasing downward force from above. During uplift, land, as well as the sea floor, rises. The outer shell of the earth, the crust, divides into moving sections called plates.
Mantle is a layer on planetary body which is made up of minerals. Mantle is solid as it is made up of heavy metals and solid rocks which makes it rigid.
A mantle is a layer inside a planetary body bounded by a core and on the above by a crust. Mantle is made up of rock or ices, and is generally the largest and most massive layer of any planetary body. Mantles are on the planetary bodies that have undergone differentiation by density.
The mantle is composed primarily of heavy metals, such as iron, nickel, and others. The state of the mantle was described as plastic. Many divide the mantle into further such as the asthenosphere and lithosphere.
Mantle rocks are soft and able to move over the course of millions of years at great depth and pressure. The transfer of heat and material in the mantle helps to determine the landscape of the planet.

Answer:
If the mantle is made out of soft rock, then I think it would melt due to the heat, but if it was hard, it would just burn, so I firmly believe the rock is hard.

Answer:
Explanation:
This is usually because when they first became fossils, they embedded into the ground. Over many years afterwards, more layers came to cover that layer and so on. Newer fossils would be embedded into newer layers. That's why the older ones tend to be found the deeper you look.
Answer: Well probably because of the fact that over time the rocks stack up on top of each other because of weathering and erosion and as they stack they get deeper and deeper, so fossils that were at the top one time will slowly sink as the time progresses.
