●First Burn:skin becomes red and sensitive
●Second Burn:skin will be red,blistered,swollen,possibly white patches
●Third Burn:white or charred, dead skin becomes tough and leathery
Answer:
Considering that homeostasis is restored in the patient, his blood pH range would return to normal levels (7.35-7.45), and his hydrogen ion concentration in the blood would normalize. The effect of normalizing the body by getting rid of excess hydrogen ions is achieved by concentrating these ions into the urine for expulsion, therefore increasing the pH levels of urine.

Explanation:
Acidosis is the condition wherein excessive acid build-up within the body causes the blood pH to become lower than normal (normal pH range 7.35-7.45). This may be due to an excessive loss of bicarbonate in the blood, also known as metabolic acidosis, or due to an impairment in the elimination of carbon dioxide in the blood from poor lung function, also known as respiratory acidosis. The body's natural response to acidosis is to increase the breathing rate to eliminate carbon dioxide in the blood, restoring the natural pH of the body.
In people with diabetes mellitus type I, the lack of insulin causes cells to breakdown fat aside from glucose as an energy source. This process produces ketones as a metabolic by-product for energy but also causes the body to be acidic. This is known as diabetic ketoacidosis.
Answer:
c) allowing an organism to adjust to changes in environmental conditions
Explanation:
A stimulus can be defined as any change in the external or internal environment that produces a corresponding response in the organism. These responses enable the organism to maintain an internal equilibrium (homeostasis). Gene expression in prokaryotes, which are the simplest forms of life, is highly regulated by environmental stimuli. Some examples of stimuli known to regulate gene expression patterns in prokaryotic organisms are light, water, pressure, temperature, etc.
<h2>Anterior-posterior orientation</h2>
Explanation:
Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established
- Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
- They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
- Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
- Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants
