Explanation:
It is C. A message is distributed across the plasma membrane.
Answer:
To produce 2x amount of the DNA.
Answer:
The correct answer is - option D. intramembranous ossification
Explanation:
Conversion of mesenchymal tissue into bone directly is known as intramembranous ossification. The bone formation is the process that involves the conversion of mesenchyme or primitive connective tissue from laying of bone directly. It is made up of granular cells and fibers in the matrix.
It is the formation of tissue of bone in a fetal without any template or cartilage base during fetal development.
Thus, the correct answer is - option D. intramembranous ossification
In cell signalling, after a signal is sent, signal molecules bind to receptors on target cells and some activity in a target cell changes.
There are three stages in cell signalling :
1. The process of reception occurs when a signalling molecule from the extracellular environment is recognized by a cell. The chemical signal, which is also known as a ligand, is recognized as a signal when it attaches to a receptor protein either on the exterior of the cell or on the interior of the cell.
2. Transduction: This process occurs when the signalling molecule interacts with the receptor, which causes a change in the protein that makes up the receptor. The process of transduction is kicked off by this modification. In most cases, signal transduction occurs through a pathway that consists of numerous stages. The signal transduction route contains relay molecules, each of which influences the subsequent molecule in the pathway.
3. Reaction: In the third and last step, the signal causes a certain cellular response.
