In a rooted phylogenetic tree, each node ... phylogenetic tree that explicitly represents evolutionary time through its branch spans. A spindle diagram (often called
Iron, oxygen and water react with the iron creating a substance known to us as rust.
Hope this helps.
Answer:
C) an interneuron
Explanation:
A reflex arc is a neural pathway that controls a reflex action. In a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through an interneuron because an interneuron enables communications (i.e a pathway for information passage) between a sensory neuron and motor neuron. They play vital roles in reflex actions, neuronal oscillations, neurogenesis in an adult mammalian vertebrate brain.
The correct answer is option b. higher levels of hemoglobin.
The partial pressure of the oxygen decrease as the height from the sea level is increased. Due to the decrease in the partial pressure, the amount of the oxygen delivered by the hemoglobin to cell decrease. So, in order to cope up the condition, the amount of the hemoglobin in the blood is increased. the increased amount of the hemoglobin delivers more oxygen than the normal amount of hemoglobin can do, so, it help in survival at low oxygen levels.
