What do water molecules in the air tend to stick to?

Water molecules in the air tend to stick to surfaces that are hydrophilic, meaning they have an affinity for water. Examples include glass, metal, and certain types of plastics. These surfaces allow water molecules to form a thin film known as condensation.


What is the nuclear envelope's job?

The nuclear envelope surrounds the nucleus and serves as a barrier between the nucleus and the cytoplasm. It helps regulate the passage of molecules in and out of the nucleus, protecting the genetic material inside. It also provides structural support to the nucleus.


Why iodine dissolve readily in CCl4?

Iodine dissolves readily in CCl4 due to the presence of London dispersion forces between the iodine molecules and the non-polar CCl4 molecules. These weak intermolecular forces allow for iodine molecules to be dispersed throughout the CCl4 solvent.


How can a material be porous but also impermeable?

A material can be porous but also impermeable due to its surface structure. The molecular level can allow molecules of air to pass through, but not water molecules.many materials, such as GoreTex, has a surface structure, that at a molecular level can allow molecules of air to pass thru but not molecules of water. This way, you can be protected from falling rain, but also have a material that will "breathe" and wont keep you feeling muggy inside.


Are inorganic molecules large or small?

Even though the question is a little vague the answer is no. The specifics of carbon atoms allow them to form an almost endless variety of molecules among themselves or with the addition of other atoms (commonly hydrogen, oxygen, nitrogen etc.). That doesn't mean that there are no complex inorganic molecules (eg perovskites) but in general organic chemistry is more versatile and therefore rich and complex

What is the function of Nuclear in a cell?

Nuclear pores allow molecules to move through the nuclear envelope.


What is a nuclear pores function in a cell?

Nuclear pores allow molecules to move through the nuclear envelope.


What structures allow genetic material to pass through the nuclear membrane?

Nuclear pore complexes (NPCs) are structures that span the nuclear membrane and allow the passage of molecules, including genetic material such as DNA and RNA, in and out of the nucleus. NPCs regulate the transport of these molecules by recognizing specific signals on the molecules themselves.


What is the openings in the nuclear membrane?

pores


What is the muclear envelope?

The nuclear envelope is a double membrane structure that surrounds the nucleus of a cell. It acts as a barrier between the nucleus and the cytoplasm, regulating the passage of molecules in and out of the nucleus. It also contains nuclear pores that allow for the movement of specific molecules.


What is formed where the two layers of the nuclear membrane fuse?

A structure called the nuclear pore complex is formed where the two layers of the nuclear membrane fuse. These pores allow the transport of molecules such as proteins and RNA in and out of the nucleus.


Holes in the nuclear membrane where mRNA leaves to move to the ribosome?

The nuclear pores in the nuclear membrane allow mRNA to exit the nucleus and move to the ribosomes in the cytoplasm for protein synthesis. These pores regulate the passage of molecules like mRNA by actively transporting them through the nuclear envelope.


Is the nucleus completely isolated from the cytoplasm of the cell by the nuclear envelope?

No, the nucleus is not completely isolated from the cytoplasm. The nuclear envelope has pores that allow for the exchange of molecules between the nucleus and cytoplasm. This allows for communication and transport of molecules between the two compartments.


Double layered membrane with pores surrounding the nucleus?

The double-layered membrane surrounding the nucleus is called the nuclear envelope. It has pores called nuclear pores which allow the movement of molecules like RNA and proteins in and out of the nucleus while regulating the passage of larger molecules. This structure helps to protect and regulate the contents of the nucleus.


Controls movement in and out of the nucleus?

The nuclear pore complex controls the movement of molecules in and out of the nucleus. It acts as a selective barrier, allowing only specific molecules to pass through the nuclear envelope. Signals on molecules regulate their transport through the nuclear pores.


Openings in the nuclear membrane?

Nuclear pores are the openings in the nuclear membrane that allow the passage of molecules like proteins and RNA between the nucleus and the cytoplasm. These pores are essential for maintaining communication and regulating transport between the nucleus and the rest of the cell.


How does RNA leave the nucleus?

RNA leaves the nucleus through small pores in the nuclear membrane called nuclear pores. These pores allow specific molecules, including RNA, to pass through and travel to the cytoplasm where they can carry out their functions in the cell.
