Answer:
b. vitamin K deficiency.
Explanation:
A normal bleeding time in association with normal platelet count, and increased prothrombin time (PT) and INR, is indicative of vitamin K deficiency.
This ultimately implies that, when an individual is suffering from vitamin K deficiency, he or she would experience increased bleeding.
The answer for this question would be Integument, digestive, respiratory and urogenital.
The largest system that contact with the external environment would be integument and digestive. That makes two system has normal flora of microbes and not sterile like the other systems. Normal flora of microbes will prevent the pathogen microbe grows so it gives some benefit.
Coralline and calcareous algae build-ups are very essential for the development of coral reefs. In addition, when these coralline and calcareous algae tends to "stick" on landforms below the ocean surface, and as these life forms grows and continuously expands, they now form what we call "reefs."
The Cross-Linkage Theory or also referred to as the glycosylation theory of aging was discovered or proposed by Johan Bjorksten in the 1940s. According to this theory, the aggregation of cross-linked proteins can damage cells and tissues this slowing down the bodily processes that eventually results to aging. In recent studies, cross-linking is associated with age-related changes in the studied proteins. Furthermore, this theory stresses out that the binding of glucose to proteins can cause various problems. Once the said binding occurs, the protein becomes impaired which leads to its performance inefficiency. Living a longer life would also mean increasing the possibility of oxygen-glucose meeting and protein. Some of the known cross-linking disorders include senile cataract and the appearance of tough, leathery, yellow skin.
