If water had weak surface tension, insects would not be able to land on or walk on water.
Surface tension is the force acting on the surface of water that makes it to behave like a stretched elastic skin.
Surface tension owes to the intermolecular attraction between water molecules. The molecules at the surface of water are drawn inwards by other molecules causing the molecules at the surface to contract. This surface tension enables insects to land on or walk on water.
So, without surface tension of water, insects would not be able to land on or walk on water.

Inflammatory response can be defined is a reaction of the body to injury or destruction of tissues. This reaction serves to dilute, destroy or simply wall off the agent causing the injury and is localized around the area of injury.
Inflammatory response takes place in the following steps:
1. Tissue damage caused by injury or bacterial infection is detected.
2. Vasodilators and chemotactic factors such as histamine are released.
3. As a result, there is increased capillary permeability and blood flow to the area.
4. There is migration of phagocytes to the site of infection.
5. Phagocytes and specific serum proteins attack and destroy bacteria.
6. Inflammation dies down once intruder has been destroyed.

<span>Hemoglobin
is the part of the red blood cell that carries oxygen, and so important for
thriving. In the case of Brian, having 10.4 g/dL hemoglobin is very low. Normal
values for hemoglobin in males range from 13.5 to 17.5 g/dL. The patient has
very serious anema and note he is just 15 months old, and so needs immediate
doctor’s attention. The doctor is likely to order a blood transfusion to
elevate hemoglobin levels and stabilize the patient before ordering tests to
determine cause of anemia.</span>
