The porous structure that surrounds the nucleus is called the nuclear envelope. It consists of two lipid bilayer membranes, with nuclear pores embedded within them that regulate the passage of substances in and out of the nucleus. This structure is crucial for maintaining the integrity of the genetic material and facilitating communication between the nucleus and the cytoplasm.

What is porous structure surrounds the nucleus keeping it intact?
The porous structure that surrounds the nucleus is called the nuclear envelope. It consists of two lipid bilayer membranes, with numerous nuclear pores that regulate the exchange of substances between the nucleus and the cytoplasm. This structure helps maintain the integrity of the nucleus while allowing necessary molecules, such as RNA and proteins, to pass in and out. The nuclear envelope plays a crucial role in protecting genetic material and facilitating cellular functions.
What surrounds the nucleus to hold genetic material of a cell?
A nucleus has a membrane around it that is very similar to the cell membrane. It is called the nuclear envelope and it is a porous double membrane that separates the nucleoplasm from the cell cytoplasm.
What is a light porous volcanic rock called?
Pumice is a light, porous volcanic rock that is commonly used in beauty and skincare products for exfoliation. It forms when volcanic lava rapidly cools and traps gases, creating its characteristic porous texture.
Why does gold become porous?
Gold can become porous due to a process called dealloying, where one of the metals in the alloy is selectively dissolved, leaving behind a porous structure. This can happen when the alloy is exposed to certain chemicals or environmental conditions that cause the dissolution of one of the metals.
Are steel porous or non-porous?
Steel is typically considered non-porous due to its dense and solid structure. However, certain types of steel can have micro-pores or surface imperfections that make them slightly porous. Generally, stainless steel has better resistance to corrosion and is less porous than other types of steel.

What are porous metals?
Porous metal is a metal structure which has a number of holes.It is a new metal material which has characteristics of both porous structure and metal.
Description of nuclear envelope?
According to biologists, the nuclear envelope contains two fatty layers of membrane that surrounds and protects the nucleolus. The fatty layers include inner and outer levels which are porous and this allows for materials to come in and out of the nucleus.

Is a diamond porous?
No, diamonds are not porous because their crystal lattice structure is tightly packed, leaving no room for pores or holes. This tight structure is a key factor in the diamond's hardness and resistance to scratching.
What is the difference between porous metals and metal foams?
When you intended to make a metal full of bubbles it is called 'foam'. When you wanted a solid metal and got bubbles in it, it is called 'porous'. So 'foam' is a good thing, 'porous' is a bad thing.
A type of water animal with a porous structure?
A sponge is a type of water animal with a porous structure. Sponges are primitive multicellular organisms that live in aquatic environments and have numerous pores that allow water to flow through their bodies. They are filter feeders, extracting nutrients from the water that passes through their porous bodies.
What is the porous structure through which molecules pass?
The porous structure through which molecules pass is called a membrane. Membranes are semi-permeable barriers that allow certain substances to cross while blocking others based on their size, charge, or solubility. These membranes play a crucial role in various biological processes, such as nutrient uptake, signaling, and waste removal.
A rock that allows water to flow through it is said to be?
water The answer is actually permeable.
