The incorrect statement is option (A) the innate defenses of the body apply strictly to external pathogens, while adaptive defenses apply strictly to internal pathogens.
Immunity can be classified into two types namely, the innate immunity and the adaptive immunity. Innate immunity is the first line of defense against the pathogens. It includes the physical and chemical barriers of the immune system along with the action of the phagocytizing cells called the macrophages. Whereas, the adaptive immunity is mediated by the cells of the immune system called the lymphocytes. The B lymphocytes produce antibodies and are responsible for humoral immunity. The T lymphocytes produce the cell mediated immunity with the production of the helper T cell, cytotoxic T cells and attack the pathogens. Innate immune response is comparatively a faster immune response which can be activated by any foreign substance entering the body. Both the defenses work on external and internal pathogens.

An organ or tissue may be better able to resist damage from hypoperfusion if the: body's temperature is considerably less than 98.6°F (37.0°C)
<h3>What is hypoperfusion?</h3>
- A word used to denote "a decreased amount of blood flow" is hypoperfusion. We can refer to ischemia that arises as "hypoperfusion" when there is insufficient blood flow.
- Low blood pressure, heart failure, or blood volume loss are some of the causes of hypoperfusion. Lightheadedness, dizziness, headaches, nausea, exhaustion, and shortness of breath are typical symptoms that are made worse by being upright and made better by lying down.
- Thromboemboli are encouraged to form by hypoperfusion. Severe occlusive lesions result in hypoperfusion, which alters the quantity and turbulence of blood flow and encourages the development of both white and red thrombi, which are the building blocks of emboli.

Answer:
An increase in the number of H+ ion in the lake with many aquatic would cause cell shrinkage by the removal of water from the cell.
Explanation:
Every organism tries to maintain a constant PH inside their body to regulate the homeostasis of their body.
An increase in the number of H+ ion or proton in a lake will increase the osmotic pressure of the water present in the lake.As the osmotic pressure of Lake"s water is increased it will draw water out from the the cells of aquatic organism causing the cells to shrink thus decreasing the volume of the cell and if the H+ ion concentration rises at a high level cell death can occur.
