### process | growth:

Tumour
* Most tumours are characterized by regions of necrosis, mild and severe hypoxia and normoxia
  - can form sclerotic deposits at some stage, even myeloma
* Some tumours are very receptor positive and others less so.
* also develop in steroid treated hamsters.
* are also a frequent cause of obstruction
  - less common than in the Parotid Gland, and malignant tumours are rare
* can also arise from the bronchial tree
  - develop if the animal is exposed to chemical carcinogens
* can be benign or malignant
  - either benign or malignant
* grow around the nerve compressing it and leading to a gradual loss of hearing.
* have a nasty tendency to migrate from their origin to other organs.
* invades intrahepatic branches of the portal vein.
* originating from the thymocytes are called thymic lymphomas.
* perform no useful body function.
* tend to be more common in older female rats.

### process | growth | tumour:

Carcinoid tumour
* are rare and few centres have large experiences in their treatment
  - neuroendocrine lesions
* offer a diagnostic and therapeutic challenge.
* presents considerable problems of diagnosis because symptoms are aspecific.

Pituitary tumour
* Most pituitary tumours are benign.
* are benign and are called adenomas.

Solid tumour
* All solid tumours depend on neo-angiogenesis to grow and metastasise.
* are particularly difficult to treat.
* differ in their physiology and microenvironment from normal tissue.

Urban growth
* can lead to endless and crippling problems when it is unplanned, random and chaotic.
* is generally a story of diffusion of ownership.
* represents more than just residential densities.
* strong driver of habitat degradation and loss.

Uterine growth
* includes muscular hypertrophy and an extensive increase in connective tissue.
* starts after implantation.
* stops which in fact becomes smaller in size.

Vegetative growth
* Most vegetative growth occurs in springs.
* begins in the spring with bud swell.
* can also change the look of the surroundings.
* is associated with younger plants and the production of leaves
  - by hyphal elongation and carbon catabolism is obligatory aerobic
  - cyclical with pronounced growth flushes
* lasts longer with only four plants.
* requires for development
  - nitrogen which is absorbed from the soil
* stops when reproduction begins.

Vigorous growth
* Most vigorous growth depends upon light.
* occurs during springs

Virilization
* also occurs.
* is growth
  - the most common undesirable effect associated with anabolic steroid therapy
* refers to attaining the characteristics of a mature male.

### process:

Hatching
* denotes the action of recombination.
* enzymes Fish hatching enzymes are metallo proteinases belonging to the astacin family.
* is one of the most dangerous periods of a sea turtle s life
  - times in a sea turtle's life
* is the emergence of young animals from their eggs
  - use of linear strokes laid closely to each other to create a value or color
  - when the embryo leaves the zona pellucida and prepares for implantation
* occurs at the larval stage when the larva leaves the parent
  - only when environmental conditions are favorable for survival of hatched larvae
* prerequisite for embryo implantation in the uterus.
