Answer:   Blood contains numerous biconcave cells called erythrocyte , contained in a featureless matrix called plasma
Explanation:
Blood is a liquid contain in the body of man and animals that transport the necessary nutrients and oxygen to the cell and then takes away metabolic waste from the cell. There are numerous cells in the body which are the Red blood cells and also the red blood cell.
This red blood cell is also called erythrocyte which is the numerous biconcave cells. This white blood cells and erythrocytes are   all in the blood plasma. Both the erythrocytes  (i.e red blood cell) and the white blood cell are all contained in a featureless matrix called the plasma.
This plasma is made up of blood, water, carbon dioxide, dissolved proteins,  and hormones. 
 
        
             
        
        
        
Answer:
Plants use electric fields to communicate with bees, scientists have learned.
Bumblebees are able to find and decipher weak electric signals emitted by flowers, according to the study.
Tests revealed that bees can distinguish between different floral fields, as if they were petal colours. The electric signals may also let the insects know if another bee has recently visited a flower.
Explanation:
How bees detect the fields is unknown, but the researchers suspect the electrostatic force might make their hair bristle. A similar hair-raising effect is seen when placing one's head close to an old-style TV screen.
Flowers were already known to use bright colours, patterns and enticing scents to attract pollinators.
