The outer periphery of the inter-vertebral disk is composed of strong fibrous tissue called the Annulus fibrosus. This is a tough circular exterior of the inter-vertebral disc that surrounds the soft inner core, the nucleus pulposus. The outer portion is composed of a ring of ligament fibers that encases the inner core of the disc and securely connects the spinal vertebrae above and below the disc.
P700 is photosystem I. It includes chlorophyll a 670, 680, 695, 700, Chlorophyll b, carotenoids. The active reaction center of photosystem is p700, as it absorbs light of a wavelength longer than 680nm.
P680 or the photosystem II has the following pigments: chlorophyll b, 660, 670, 680, 695, 700, phycobilins, and xanthophylls. The active reaction center, in this case, is p680 of chlorophyll a, as it absorbs the light having a wavelength shorter than 680nm.
Concentration gradient differs whether the solution is greater or lesser anticipating if it's hypertonic, hypotonic, or isotonic.
Answer:
“The increase in impervious or hard surfaces, including rooftops and pavement, decreases the amount of water that soaks into the ground, or infiltrates. This increases the amount of surface runoff.” notice many visible changes, includ- ing housing developments, road networks, expansion of services, and more.
Explanation:
Cancer cells affect the cell cycle by not following the checkpoints and dividing abnormally and not getting destroyed by the process of apoptosis leading to the formation of tumours.
In the cell cycle during the mitotic phase the cell divides resulting in two daughter cells and segregation of DNA occurs in this. In cell cycle, there are checkpoints of signalling pathways which determine when the cell has to grow and divide. The healthy cells follow the cell cycle.
Explanation:
Cancer cells become immortal and result in faulty proteins which are not required by the system. The cancer cells grow uncontrollably and are abnormally shaped.
The cell cycle has check points at S phase and G2 phase before it enters the Mitotic phase of division. Normal cells follow the checkpoints.
