This is false. Organisms may play several important roles in an ecosystem. Consider for example and ocean shore environment occupied by a particular species of crab. The crabs are scavengers and eat any organic matter they encounter. They therefore play an important role in the cycling of nutrients in the ecosystem. The crabs are however also an important source of food for a range of other species occupying the same habitat, including octopi, certain fishes and sea otters. Therefore, the crabs are an important part of the food web in the ecosystem. Many species similarly occupy multiple important roles in an ecosystem.
The answer is Psychoneuroimmunology.
This is the study pf the interactions among behavioral, neural and endoicrine, and immune processes. The brain communicates with the immune system through the autonomic nervous system and neuroendocrine activitry.
Outer core is the answer - Appex
The answer is bold dependent and underline independent. In addition to biology laboratory examination, independent variable is the most important variable in which this variable is manipulated in what the investigator differs in the experiment. Dependent variable in the experiment, one variable will be stately or calculated or experimental in reaction to experimental situations.
Answer:
The correct answer is option C.
Explanation:
PAX5 refers to the member of the Pax gene family, which is, accountable for conducting the genetic information, which will encode the Pax-6 protein. It functions as a master control gene for the maturation of eyes and other sensory organs. Pax6 functions as a regulator in the formation of patterns and coordination needed for the proliferation and differentiation to take place effectively. This ensures that the procedures of oculogenesis and neurogenesis are taking place efficiently.
The PAX6 gene was the outcome of evolution in earlier animals comprising eyespots or eyes. The similar PAX6 gene generates distinct kinds of eyes in distinct species because of the difference in its control of PAX6 expression. At the time of the evolution of vertebrates, the biological clock opsin’s rh gene was chosen as a gene for visual receptor pigments.
