Which cell junction will allow the movement of molecules between two plant cells?
Plasmodesmata is the cell junction in plant cells that allows the movement of molecules between adjacent cells. These junctions are channels that pass through the cell walls of plant cells, facilitating the transport of water, nutrients, and signaling molecules between neighboring cells.
Why a biome is an open system?
A biome is considered an open system because it exchanges energy and matter with its surroundings. This exchange allows for inputs and outputs to flow in and out of the biome, influencing its dynamics and functioning. It also allows for interactions between the biome and neighboring ecosystems.
Why biome considered as a open system?
Biomes are considered open systems because they exchange both energy and matter with their surrounding environment. Energy from the sun is constantly entering the biome, while matter such as nutrients and gases are exchanged with neighboring ecosystems. This continual exchange allows for the biome to maintain its structure and function.
What is cellular exchange?
Cellular exchange refers to the process by which cells in a multicellular organism communicate with each other through signaling molecules such as hormones, neurotransmitters, and cytokines. This communication allows cells to coordinate their activities and respond to changes in their environment, helping maintain homeostasis in the body.
What property of water molecules allows them to form a hydrogen bond?
The polarity of water molecules, due to uneven distribution of electrons, allows them to form hydrogen bonds. This is because the positively charged hydrogen atoms are attracted to the negatively charged oxygen atoms of neighboring water molecules, creating a weak electrostatic attraction known as a hydrogen bond.
A junction that is a protein channel linking the cytoplasms of adjacent cells is called?
A junction that is a protein channel linking the cytoplasms of adjacent cells is called a gap junction. This structure allows for direct communication and sharing of ions and small molecules between neighboring cells.
Which cell junction will allow the movement of molecules between two plant cells?
Plasmodesmata is the cell junction in plant cells that allows the movement of molecules between adjacent cells. These junctions are channels that pass through the cell walls of plant cells, facilitating the transport of water, nutrients, and signaling molecules between neighboring cells.
What is a patch where two cells are physically joined together?
A gap junction is a specialized intercellular connection between two cells that allows for direct communication and passage of ions, small molecules, and signaling molecules. This type of junction is important for coordinating the activities of neighboring cells in tissues like the heart and nervous system.
What occurs when Molecules exchange places?
When molecules exchange places, they undergo a process known as diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached. This movement allows molecules to mix and redistribute throughout a space.
21 what types of routing protocols allows routers to exchange information about best paths with their neighboring routers only?
distance vector routing
What is the purpose of a Gap junction?
A gap junction enables connections between two different animal cells. It allows ions and molecules to pass between the cells freely and helps the organism to continue to exist.
What type of cellular junction that forms when a channel is formed between two adjacent plasma membrane?
A gap junction forms when a channel is created between two adjacent plasma membranes. This type of cellular junction allows for direct communication and passage of small molecules between the two cells.
What is a small protein channel that allows the passage of ions and small molecules between cells?
A gap junction is a small protein channel that allows the passage of ions and small molecules between cells. Gap junctions play a crucial role in facilitating communication and coordination between cells.
What determines the cohesiveness of water molecules?
The cohesiveness of water molecules is determined by hydrogen bonds. These bonds form between the hydrogen atoms of one water molecule and the oxygen atoms of neighboring water molecules, creating a strong attraction that allows water molecules to stick together.
Why a biome is an open system?
A biome is considered an open system because it exchanges energy and matter with its surroundings. This exchange allows for inputs and outputs to flow in and out of the biome, influencing its dynamics and functioning. It also allows for interactions between the biome and neighboring ecosystems.

A gap junction enables connections between two different animal cells. It allows ions and molecules to pass between the cells freely and helps the organism to continue to exist.
Explain why water molecules are capable of hydrogen bonding with 4 neighbouring water molecues?
Water molecules contain polar covalent bonds due to the unequal sharing of electrons between oxygen and hydrogen atoms. This polarity allows water molecules to form hydrogen bonds with neighboring water molecules, as the slightly positive hydrogen atom attracts the slightly negative oxygen atom of another water molecule. This unique structure and polarity of water molecules make them capable of forming hydrogen bonds with up to four neighboring water molecules, resulting in strong intermolecular forces.
