Answer:
Explanation:
A moving charge causes a magnetic field and a moving magnet causes an electric field. If you change your frame of reference to that of the charged particle, the magnetic field disappears. Same is true for the magnet. Changing your reference frame to that of the magnet will make the electric field disappear.
Answer:
Explanation:
Proteins are involved in almost every function of cell and inside the body and each protein is specific for its role. Some of them are
1) Protein constitute major part of structure of cell. Proteins are major constituent of cell membrane along with lipids.
2) Enzymes which are proteins in nature catalyze all the important chemical reactions inside and outside the cell e.g transporting material across the cell, synthesizing and repair of DNA
3) Hormones which are proteins play important role in the regulation of metabolic reactions inside the cell
4) Regulation of cell division is performed by DNA-associated proteins
5) Proteins plays important role in storage of iron inside the cells
6) Proteins can be stored as fats inside the body and used as energy when needed by cells for its metabolic activities.
Answer:
C. Thrombocytes
Explanation:
Blood is a tissue composed of many cells, which include; red blood cells (erythrocytes), white blood cell (leukocytes), platelets (thrombocytes) etc. Of these three types of cells, thrombocytes also known as Platelets are small fragments of a cell with a disk-shape whose primary function is in blood clotting.
In contrast to erythrocytes, and leukocytes (monocytes, lymphocytes) as mentioned in the question, thrombocytes or platelets are not actual whole cells but rather small portion of a cell.
