Answer:
Explanation:
(A) PaO₂ below normal: PaO₂ is used to describe the partial pressure of oxygen dissolved in the blood. When it is below normal, it indicates the individual isn't getting enough oxygen hence there is low pressure of dissolved oxygen in the blood. This sign/symptom falls under the Respiratory/oxygenation data cluster.
(B) Dyspnea on exertion: Dyspnea is a term used to describe shortness of breath while dyspnea on exertion is when an individual runs out of breath as a result of not been able to breath deeply/properly during or after an exercise. This sign/symptom also falls under the Respiration/oxygenation data cluster.
(C) Productive cough: This is a type of cough that produces/forces mucus out of the airway (thereby clearing the airway). This sign/symptom from this description is also Respiratory/oxygenation data cluster.
(D) Oxygenation saturation 92%: Oxygen saturation is when the body can supply enough oxygen to the cells and tissues within it's system. This sign/symptom is also a Respiratory/oxygenation data cluster.
(E) Feels "too tired to do much": This can also be referred to as fatigue. This is usually as a result of inadequate energy produced (usually from glycolysis) in the body. This sign/symptom, from this description, is a Reduced energy level data cluster.
(F) Requires frequent rest periods: This usually occurs as a result of imbalance in the body's metabolism. Here, the body uses more energy than it produces; more anabolic processes (energy requiring) than catabolic processes (energy produced/released). This sign/symptom, from this description, is a Reduced energy level data cluster.
The answer is hox gene.
Hox genes are responsible for an embryo's body plan. They determine different body structures - legs, vertebrae, antennae, wings, depending on groups. Mutation in hox genes is serious mutation since it affects the early stages of embryo and consequently, normal development. If a mutation occurs in the hox gene for legs growth, the legs will not develop.
Answer:
Due to continuous global warming, the oceans tend to gain more heat and hence the temperature rises. In the current century, the heated conditions of the oceans can be threatful for the human population. Also, the increase in the sea levels will have serious consequences on the health of mankind and their quality of life.
Answer:
Option D is a correct answer
Explanation:
An adaptation is adapted to suit the environment as every environment is different.
Different environment aids to different kind of adaptations that perfectly suits the animals living there.
The adaptation of an animal living in the desert region will have adaption to work in hot climate. The plant that grows in a desert area have no leaves and broad stem to store water.
The animals that live in the polar regions have thick fur to provide insulation and heat to live in polar region.
