Answer:
Part of the extracellular matrix secreted by osteocytes. (Ans. B)
Explanation:
Cells which are present on bones are known as osteocytes. Bone is composed of extracellular matrix, and cells. There are three types of cells which are present in the bones:
1) Osteoprogenitor cells.
2) Osteoblast.
3) Osteocyte.
Extracellular matrix is composed of organic matrix consisting glycoproteins, proteoglycans, osteocalcin also known as calcium binding proteins, and osteonectin which anchors bone mineral to collagen.
Answer:
The reason is probably so that each can fit equally well onto the ribosome and carry out its function
Explanation:
The three-dimensional structure or tertiary structure of tRNAs is conserved and crucial for the interaction : it is L-shaped 3D structure that allows them to fit onto the ribosome (its P and A sites). This is important for the function of tRNA: to be link between mRNA (carries the information from DNA) and ribosome (performs protein synthesis-translation).
Has an iron ion (and it's called haem btw)
Answer:
root
Explanation:
the radicle is the first part of a seedling (a growing plant embryo)
Answer:
The correct answer is - during active cellular growth and after cell lysis
Explanation:
Endotoxins, also known as LPS, are part of the outer leaflet of the outer membrane of the cell wall of gram-negative bacteria. These LPS especially Lipid A LPA released into the circulation when there is a disruption of the intact bacteria or after cell lysis. These are present in cell-associated bacteria such as Gram-negative pathogens such as Escherichia coli, Salmonella, Shigella, Pseudomonas, and others.
