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.
Nitrogen fixers are bacteria
Its estimated that during sprint events approximately 95% of energy production comes via the anaerobic system (85% phosphate, 10% anaerobic glycolysis), and only 5% from aerobic oxygen. Thus, the 100m sprint is an anaerobic event relying heavily on energy supply from the ATP-PC system!
For population to be healthy, factors such as food nutrients water and space must be available, limiting factors include low food supply and lack of space. Limiting factors can lower birth rates increase death rates or lead to emigration
I hope this helps. that is caused by the differences in temperature
