Intercellular communication involves an electrical charge moving along a cell membrane. These are communicated through electrical charges flowing in between the cells like in the synaptic gaps of neurons.
Explanation:
Cellular communications are essential for the cell to communicate and control the various cellular activities both within and outside the cell.
Explanation:
Intracellular communications are those which take place within a cell. These signaling pathways also referred transduction pathways are triggered by extracellular communication signals which transmit through biochemical interactions to the nucleus. Eg., action of cyclic AMP.
Intercellular communications is the transfer or communication of information in between cells. These signaling pathways are communicated directly and indirectly. . Eg., neuron transmission and hormone secretion

Answer:
Option C, varicella-zoster virus
Explanation:
The synonym for varicella-zoster virus is VZV and it is responsible for causing chicken pox in primary infection and shingles after the reactivation of latent VZV infection
It is a DNA virus that belong to the group of herpesvirus. All herpesviruses have the capability to persists in the body after primary infection as latent infection. These viruses survive for a short duration in the environment.
Hence, option C is correct.
Answer: Malignant tumor-
cancer cells are contained within their tissue.
Maglinant tumor-- Cells of this type of tumors have the potential to , escaping their tissue and spreading to other locations within the body.
Benign tumour-pre-cancerous cells highly disorganized metastasize.
Explanation: Tumor is an abnormal growth in the cell.
Benign tumor is a tumor that do not spread within the cell and are not cancerous. The can grow to very large and are removed by operation. It can be very dangerous when its big and press other tissues especially when located in the brain. It may not require any treatment when it is not threatening. Example of benign is fibroid
Malignant tumour are tumour that are cancerous and can spread to other tissues. They can be transported via the blood stream to other tissues. Malignant tumour grows fast and can spread to nearby tissues example is breast cancer when not diagonize earlier can spread to other tissues. They required medical attention and can be removed through operation, some require chemotheraphy. Some malignant tumour grows back even after removal.
