Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
Explanation:
Current treatment for Wilms' tumor includes Surgery and radiation.
Wilms tumor is a type of cancer that starts in the kidneys. It is the most common type of cancer in children. It is a rare kidney cancer that primarily affects children. Surgery treatment to remove the tumor is the first treatment if it can be done, followed by radiation therapy. The entire abdomen will be treated if there is still some cancer left after surgery. If the cancer has spread to the lungs, low doses of radiation might also be given to that area.
Option (B) specialised phagocytic cells
<h2>Role of colchicine </h2>
Explanation:
The correct positioning of the Golgi apparatus in the cell is dependent on intact microtubules
- Golgi complex consists of several tubules and sac like structure present in cytoplasm of all eukaryotic cells
- Microtubules are hollow,inextensible and cylindrical structure which is responsible for anchoring of membrane bound organelles
- During cell division,microtubules disassemble and then reassemble and forms mitotic spindle apparatus and catalyse movement of chromosome
- Colchicine tightly binds with the free tubulin dimer and prevent its polymerization
- In this case mitotic spindle apparatus do not assemble and cell unable to do partitioning of chromosomes into two groups and arrest cell division
