What is the part of an aquifer in which the pores are partly filled with air and partly filled with water?
The Zone of Ariation
What does Standard and pores mean?
Standard and Poor's is a company involved in financial analysis. It is probably best known for its credit rating.
What is a real life example of the nuclear membrane?
It is like the borders of a city with small gateways to let people come out and have fresh air. In an actual nuclear membrane, it resembles pores to let waste material come out and good stuff come in.
What is the function of the clitellium?
A thickened section on earthworms that contains male and female sex organs. After exchange of sperm takes place between two different worms, a mucus and chitin cocoon forms around the female pores and fertilized eggs are deposited.
Some examples of scientific theories and scientific laws?
Michael OrjiYear 7 Sapphire2nd November 2009Newton's laws of motionThis laws describe the relationship between the forces acting on a body and the motion of that body. They were first compiled by Sir Isaac Newton in his work Philosophiæ Naturalis Principia Mathematica, first published on July 5, 1687. Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.Newton's law of universal gravitationNewton's law of universal gravitationstates that every object in this universe attracts every other object with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centres. This is a general physical law derived from empirical observations by what Newton called induction.[1] It is a part of classical mechanics and was formulated in Newton's work Philosophiae Naturalis Principia Mathematica ("the Principia"), first published on 5 July 1687. (When Newton's book was presented in 1686 to the Royal Society, Robert Hooke made a claim that Newton had obtained the inverse square law from.The law of cell.The cell was first discovered by Robert Hooke in 1665. He examined very thin slices of cork and saw a multitude of tiny pores that he remarked looked like the walled compartments of a honeycomb. Because of this association, Hooke called them cells, the name they still bear. However, Hooke did not know their real structure or function. [1] Hooke's description of these cells (which were actually non-living cell walls) was published in Micrographia.[2]. His cell observations gave no indication of the nucleus and other organelles found in most living cells.The Boyle law.A law of gases which states that at constant temperature the volume of a gas varies inversely with its pressure. This law, formulated by Robert Boyle (1627-1691), can also be stated thus: The product of the volume of a gas times the pressure exerted on it is a constant at a fixed temperature. The relation is approximately true for most gases, but is not followed at high pressure. The phenomenon was discovered independently by Edme Mariotte about 1650 and is known in Europe as Mariotte's law.
Do materials move into the nucleus do pores in the nuclear membrane?
Yes, materials move into the nucleus through pores in the nuclear membrane.
How does the MRNA get out of the nucleus?
mRNA is transported out of the nucleus through nuclear pores in a process called nuclear export. Specific proteins recognize and bind to the mRNA molecules, facilitate their transport through the nuclear pores, and into the cytoplasm where they can be translated into proteins.
How do materials pass in and out of a cell nucleus nucleus?
A+ through nuclear pores
Which part of the cell has pores that control the movement of chemicals in?
The nuclear envelope, which surrounds the nucleus, has pores called nuclear pores that control the movement of molecules such as RNA and proteins in and out of the nucleus. These pores help regulate the flow of substances between the nucleus and the cytoplasm.
What are the little dimples on the surface of nucleus?
The pores.
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.
A double membrane that is covered with pores?
The organelle that fits this description is the nucleus. It has a double membrane called the nuclear envelope that is covered with pores known as nuclear pores, which regulate the passage of molecules in and out of the nucleus.
What structures permit the passage of protein into the nucleus and ribosomal subunits out of the nucleus?
Nuclear Pores
Which feature enables the nucleus to send and receive information through the nucleus membrane?
pores
What part of the cell is full of holes?
The nucleus- the holes in the nucleus are called "nuclear pores".
Through what parts of the nucleus do materials enter and leave?
Nucleus is enclosed in double walled nuclear membrane. Nuclear membrane at certain distance have pores in them which are called nuclear pores. Nuclear pores are very selectively permeable.
Controls movement of materials in and out of nucleus?
Nuclear pores.
