Interstitial growth is the type of growth that occurs within cartilage and results in bone elongation.
It occurs because chondrocytes are capable of dividing and form a cluster of two to four or more cells in a gap.
These groups of chondrocytes are known as isogenic groups or cell nests and they increase the cartilage from within.
In this process it happens because they descend from other chondrocytes that have undergone several mitotic divisions and continue dividing.
Once cytoplasmic constriction occurs in dividing cells, a septum of intercellular substance develops between them, separating the daughter cells.
In this way, interstitial growth develops two types of dispositions:
- If mitosis is carried out in only one direction, we have a group of aligned chondrocytes (axial isogenic group).
- If the divisions are carried out in all directions, we have a coronary isogenic group.
In the epiphyseal lines of long bones, the cell division of chondrocytes occurs in one plane, resulting in the ordering of long columns, which are subsequently invaded by bone tissue.
The division of the chondrocytes and the secretion of a new matrix between the cells, gives rise to a bone elongation of the cartilage from the inside.
Therefore, we can conclude that interstitial growth is the type of growth that occurs within cartilage and results in bone elongation.

Phenol red broth base is the media that is used to grow most organisms and a large amount of a potentially fermentable sugar.
For the purpose of microorganism differentiation, phenol red broth base is advised to ascertain the fermentation response of carbohydrates.
Gram negative bacilli can be recognised with it, particularly Enterobacteriaceae. It includes one carbohydrate, a Durham tube, peptone, and phenol red (a pH indicator) (glucose, lactose, or sucrose).
When a carbohydrate is utilised by an organism, an acid byproduct is produced, which causes the media to turn yellow. If the organism can use the peptone but not the carbohydrate, ammonia is produced as a byproduct, which raises the pH of the medium and colours it fuchsia.
A gas byproduct could be created once the organism is able to utilise the carbohydrate. If so, the Durham tube will become caught by an air bubble. Gas will not be created and no air bubble will emerge if the organism is unable to use the carbohydrates .

A beacause not everything happens to all cells
Answer:
Its how you see it.
Explanation:
1.Life on Earth is based on carbon, likely because each carbon atom can form bonds with up to four other atoms simultaneously. This quality makes carbon well-suited to form the long chains of molecules that serve as the basis for life as we know it, such as proteins and DNA.
2.All life on earth <em><u>can be thought</u></em> of as "carbon-based." Just be careful about turning this around backwards. It is true that all living things contain carbon compounds... but the opposite is not true. Just because a certain material is referred to as organic does not mean it is or ever was alive.
