A herniated disk occurs when nucleus pulposus bulges from the interior of the disk, slipping it out of alignment in the spine. As a result, the vertebrae on either side of the disk compress together and put pressure on surrounding nerve tissue. Many factors can contribute to a herniated disk...
What does a cell membrane do? Cell Membranes: Cell membranes are a vital part of any type of cell. Eukaryotic and prokaryotic cells are different in many ways, yet both of them have cell membranes. Eukaryotic cells even have membranes inside their main membrane, surrounding the smaller organell...
The nucleus contains DNA separated into a number of chromosomes, with the total number varying between species (humans have 46). During the process of mitosis, the nuclear membrane dissolved, chromosomes that have already been duplicated in pairs are pulled apart, and the nucleus and cell divide ...
Eukaryotic cells, in addition to having their genetic material included within a nucleus, feature structures andorganellessuch as mitochondria and Golgi bodies that have their own double plasma membrane, which is similar in construction and content to the cell membrane itself. The medium in which the...
1. What is the control center of the bacterial cell? A Prokaryotic Cell: A bacteria is made up of aprokaryotic cell.Prokaryotes are very simple, with few organelles and no membrane-bound nucleus. Although very simple structures, bacteria thrive and reproduce in almost any type of environment....
What is the simplest cell structure without compartments or a nucleus called? What is the membrane protein that provides a passageway across the cell membrane through which an ion can diffuse? What is the name of the membrane of the vacuole surrounding the material fuses with the cell membrane ...
Answer 1:Due to the extremely small size ofamoeba cell, they lack a nervous system. Furthermore, their communication takes place through the interaction of the cell membrane with the surrounding outside world. In response to a stimulus that is alimentary, irritant, and noxious, intracellular comm...
Cells provide structure and support to the body of an organism. The cell interior is organised into different individual organelles surrounded by a separate membrane. The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth. ...
A lumbar herniated disc is a condition in which the gel-like center of a disc in the lower spine ruptures through the outer...
These mechanisms might be at an atomic level, where the cloud of electrons surrounding the nucleus of an atom is displaced, resulting in an atom having a slightly positive charge on one side and corresponding negative charge on the other. It can also occur at a molecular level, due to ...
