What is A thin sheet of aluminum can block?
In terms of nuclear radiation, a thin sheet of aluminium is capable of blocking both alpha particles (helium nucleus: 2 protons + 2 neutrons) and beta particles (electrons or positrons).
How does six feet of DNA fit into the nucleus?
DNA, or deoxyribonucleic acid, is bunched up and wound together in order to fit into the nucleolus. It is very thin, so it occupies a small space. It is almost as thin, even thinner, than one strand of hair.
What are the differences between galvanising and tinning?
Galvanizing Tinning 1. Galvanizing is the process of cover- ing iron or steel with thin layer of Zn 1. In tinning, steel is covered with a thin coat of tin to prevent corrosion 2. Zinc protects iron sacrificially 2. Due to noble nature tin protects base metal 3. Zinc protecte iron even when coating of zinc is punctured 3. If the coating is puncture intense corrosion of steel occurs. 4. Since zinc is toxic galvanized uten- sils are not used for storing food 4. Since tin is non-toxic tinned contain- ers can be used even for storing food.
What are the different types of humidity and what effects do they have on the hair?
depends on your genes or the type of hair you have. if you have naturally thick or curly hair, its tends to get frizzy in heat whereas if it is naturally thin or straight/wavy then it wont get as frizzy due to the hairs structure
What is the soft yellow metal than can be hammer into thin sheets?
malleable can be hammered into thin sheets
What protects the nucleus in a cell?
The nuclear membrane, also known as the nuclear envelope, surrounds the nucleus, protecting it and regulating the passage of materials in and out of the nucleus. It is a double membrane structure with pores that control the movement of molecules like proteins and RNA. Additionally, the nuclear lamina, a network of proteins, provides structural support to the nucleus.
What is the thin structure that surrounds a cell known as?
The thin structure that surrounds a cell is known as the cell membrane, or plasma membrane. It acts as a protective barrier, controlling the passage of substances in and out of the cell, and plays a key role in maintaining the cell's internal environment.
What is thin flexible structure that surrounds an animal cell and is found below the cell wall in a plant cell?
the cell membrane
Which cellular structure contains thin strands of DNA known as chromatin?
The nucleus contains thin strands of DNA known as chromatin. Chromatin is made up of DNA and proteins, and it packages the DNA to fit inside the nucleus of a cell.
What surrounds a plant cell and protects it?
The thin structure that surrounds the cytoplasm of a cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa. However plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
What is the name the part of the cell that surrounds the animal cell?
The thin structure that surrounds the cytoplasm of an animal cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa.
What is the thin air that surrounds the earth?
atmosphere
What is a thin structure that surrounds a cell?
The thin structure that surrounds the cytoplasm of a cheek cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa. However plant cells, in addition to the cell membrane also have the cell wall outside the cell membrane. This provides mechanical rigidity to the cell and prevents the flow of larger particles.
What is a thin layer of air that surrounds the earth?
The Atmosphere.
What is a thin layer of air that protects the Earth's surface from extreme temperatures?
The atmosphere is the thin layer of air that surrounds the Earth and helps regulate its temperature by trapping heat from the sun. This layer acts like a blanket to protect the Earth's surface from extreme temperature fluctuations.
What is the thin structure surrounding an animal cell?
The thin structure that surrounds the cytoplasm of a cheek cell is called as cell membrane. This is present in most plant, animal and fungi cells. It is a selectively permeable structure and allows the flow of ions and particles from the inside of the cell to the outside and vice-versa.
