Answer: i think, Endochondral ossification occurs at two distinct sites in the vertebrate long bone – the primary (diaphyseal) and the secondary (epiphyseal) sites of ossification. Bone development initiates at the primary site. The secondary (epiphyseal) site is under independent control and is ossified later (Figure 1b).
<span>The atmosphere of Venus is mostly carbon dioxide, 96.5% by volume. Most of the remaining 3.5% is nitrogen. Early evidence pointed to the sulfuric acid content in theatmosphere, but we now know that that is a rather minor constituent of theatmosphere.
T</span>he atmosphere of Neptune consists mainly of hydrogen and helium, but about 2.5-3% of the atmosphere is methane. Like Uranus, clouds in Neptune's atmosphere<span> are composed of crystals of methane.</span>
Answer:
Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. And most importantly decomposes make vital nutrients available to an ecosystem primary producers- usually plants and algae.
The ganglia are formed from the cell bodies of a group of neurons. The ANS or autonomic nervous system associates with the CNS (central nervous system) and the somatic nervous system with the help of ganglia. The ganglia accommodate the cell bodies of sensory (afferent) and motor (efferent) cell bodies of the ANS.
The sympathetic ganglia are situated near to the central nervous system. The two sympathetic ganglia, which locate the cell bodies of post-ganglionic cell bodies are sympathetic trunk ganglia (situated alongside the vertebral column) and collateral ganglia (anterior to the vertebral ganglia).
