Element used for cement and glass?
The key element in cement and glass is silicon.
What is meant by a strong key in science?
From Wikipedia:Strong Key is a naming convention used in computer programming. There can be more than one component (e.g.: DLL) with the same naming, but with different versions. This can lead to many conflicts. AStrong Key (also called SN Key or Strong Name) is used in the Microsoft .NET framework to uniquely identify a component.
Parts of the animal and plant cells and their meaning?
Parts of an Animal Cell and their FunctionsCell Membrane: The cell membrane is the outer most part of the cell which encloses all the other cell organelles. The cell membrane function is to control the influx of the nutrients and minerals in and out of the cell.Cell Cytoplasm: Cytoplasm is supposed to be the matrix or gel like substance/fluid present inside the cell. It is mainly made up of water and protein material. The cytoplasm is the key site wherein all life processes occur. Read structure and functions of cytoplasm to know more on this cell organelle.Nucleus: Cell nucleus is supposed to be the brainor the control center of the cell and thus one of the most important animal cell parts. It contains the genetic material i.e. the DNA (Deoxyribonucleic acid) and the chromosomes. The DNA is made up of nucleotides which eventually help in protein formation by the process of transcription and translation.Nucleolus: Nucleolus is a dark stained area inside the nucleus mainly responsible for the protein formation using RNA (Ribonucleic acid).Nuclear Membrane: This is the porous, protective sheath that covers the nucleus which allows influx of substances and is one of the distinctive characteristics of an animal cell. Read more on nuclear membrane function.Nucleoplasm: This dense fluid inside the nucleus contains chromatin fibers, which condense to form chromosomes and genes which carry hereditary information.Mitochondria: Mitochondria are among the largest cell organelles also known as the engine house of the cells. Oxygen combines with glucose to form energy (ATP) required for metabolism and cellular activities in this organelle. It is an independent organelle having its own Mitochondrial DNA, RNA and ribosomes owing to self replication and duplication.Ribosomes: As I mentioned previously, protein synthesis (transcription and translation) takes place in ribosomes. These organelles could be bound to the endoplasmic reticulum or free floating in the cytoplasm.Lysosomes: These are membrane bound sacs containing enzymes needed to break down unnecessary parts of the cell for reuse. It mainly helps phagocytosis and promotes intracellular digestion.Centrosomes: These small organelles surrounded by the microtubules or the centrosphere, contain the centrioleswhich are responsible for the initiation of cell division.Endoplasmic Reticulum (ER): The animal cell model clearly suggests ER to be the second largest cell organelle after mitochondria since these form a series of interconnecting flattened tubular tunnels; rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The RER is mainly responsible for holding onto the proteins formed in the ribosomes, thus being rough in appearance.Golgi Apparatus: The proteins formed and bounded by the ER need to be processed so as to perform normal functions. Golgi, membranous sacs associated chiefly with the endoplasmic reticulum, do that to release the protein chains.Vacuoles: Smaller gas and membrane vacuoles filled with fluids and water are present in animal cells. Their main function is storage.Having got to know the various animal cell parts, I hope it's easy for you to understand an animal cell and its importance.
What did Lise Meitner do to change your world?
Lise Meitner was a key player in the Manhattan Project, headed by Enrico Fermi, which led to the development of the atomic bomb. The element Meitnerium (Mt), atomic number 109, is named for her.
What function does lysosomes perform in a cell?
Lysosomes degrade proteins. The kind of proteins they degrade are brought into the cell by endocytosis - they do not degrade proteins that are resident in the cell, proteasomes do that . Lysosomes fuse with the protein to be degraded and release the special class of enzymes they carry, hydrolases, that do the actual break down process. Lysosomes are also the key factor in ridding a cell of H2O2 in a cell, hence the hydrolases.
What is the key structural component of a cell's membrane.?
Cell membranes are made of a lipid bilayer with various proteins interspersed.

What is the key function for a cell membrane?
The key function of the cell membrane is to let things in and out of the cell protecting the cell from danger. It is like a gatekeeper.
If a cell membrane was in a city what would it be?
The cell membrane would be a locked door (for example) so that ONLY the people with a key can get in and the people without a key would not be able to get in.
List the three structural elements of exocrine glands?
This is the IB answer key to this Question: secretory cells arranged in layer one cell thick; cells contain secretory vesicles; cells are grouped in acini; surrounded by basement membrane; cells adjacent to duct/lumen;
What city analogy compares to a cell membrane?

What is the key biological property of a lipid bilayer?
One advantage is that it allows the cell membrane to be semi-permeable by creating a hydrophobic barrier. This keeps water from flooding into the cell, rupturing it, which is what happens to bacteria when you wash your hands with soap.
What does prokaryotic and eukaryotic mean?
A prokaryotic cell is normally a bacteria. A prokaryotic cell does not have a membrane around it's nucleus, it has loops of DNA free in its cytoplasm. A eukaryotic cell is any cell with many organelles (other parts which help it function) and a membrane-bound nucleus. The nucleus is the key difference- if it has a membrane, it is Eukaryotic/a Eukaryote. If not, it is Prokaryotic/a Prokaryote.
What type of the cell contains DNA but no nucleus contains flagella ribosomes cytoplasm and a cell membrane?
The only key characteristic is "no nucleus" because that is what differentiates prokaryotes and eukaryotes. All cells have DNA, ribosomes, cytoplasm and a membrane. Cells WITHOUT a nucleus are prokaryotes
What is a plant cell?
A plant cell is a cell found in a plant. It is different from an animal cell because it has a cell wall and chlorophlasts.
What is the key structural component of human hair?

What is inside the animal cell that the animal virus recognizes?
Viruses don't "recognize" things inside animal cells. They actually "recognize" pieces of the cell membrane. Most specifically, they recognize proteins on the surface of the cell membrane. It is like a lock-and-key mechanism. When the virus particle (the lock) bumps into a specific protein (the key) on the cell membrane, it binds to it. This allows the virus to inject its genetic material into the cell. Once the genetic material - sometimes DNA, sometimes RNA - is inside the cell, it finds its way into the nucleus, inserts itself into the cell's DNA (genes) and basically takes it over. It forces the cell's genetic machinery into making hundreds and thousands of viral parts that are then put together like automobile factory to form new viruses. Once the cell is full of them, the cell ruptures releasing the new viruses to infect other cells.
