How can blood diseases be identified lab answer key?

By counting the blood cells i.e RBC , WBC, and platelets. Also by the microscopic observation of blood smears to observe the variation in cell size and shape or overall appearance.

Explanation:

In the diseased condition the number of blood cells may vary in their count. Usually in a healthy individual the number of RBCs are 4.5 to 5.5 million cells/mm3, the number of WBCs are 5,000 to 10,000 cells/mm3 and the number of platelets are 140,000 to 400,000/mm3. Any deviation from this count indicated diseased condition. Sometimes the shape of RBC may vary like in sickle cell anemia, so by microscopic observation we can check for blood cell appearance.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
