both coasts have abundant Barrier Islands. the average longshore drift direction on both coasts is from north to south. Both coasts are rising, and so are dominated by emergent shoreline features.
Answer:
The leukocyte, commonly known as a white blood cell (or WBC), is a major component of the body’s defenses against disease. Leukocytes protect the body against invading microorganisms and body cells with mutated DNA, and they clean up debris. Platelets are essential for the repair of blood vessels when damage to them has occurred; they also provide growth factors for healing and repair.Although leukocytes and erythrocytes both originate from hematopoietic stem cells in the bone marrow, they are very different from each other in many significant ways. For instance, leukocytes are far less numerous than erythrocytes: Typically there are only 5000 to 10,000 per µL. They are also larger than erythrocytes and are the only formed elements that are complete cells, possessing a nucleus and organelles. And although there is just one type of erythrocyte, there are many types of leukocytes. Most of these types have a much shorter lifespan than that of erythrocytes, some as short as a few hours or even a few minutes in the case of acute infection.
Hope this helps :)
Explanation:
They are like the animals who fly. They do have built-in mechanisms that enable them to go up and down in the water. The downward pull is the gravity and the upward push of the buoyancy. The force of the buoyancy is equal to the weight of the fluid displaced by that object. So fishes use their swim bladder for them to be able to ascend.
