<span>Most organisms, including humans, can't use the free gaseous form of nitrogen found in the air. We need other organisms and natural processes to "fix" nitrogen into a solid form that plants and animals can use. Most of the nitrogen that plants and animals use is made by bacteria.</span>
Answer:
cell wall provides protection and structural support
Some skeletal traits that define modern homo sapiens are a small face, high rounded skull, small jaws, bony chin , vertical and high forehead, a narrow nasal aperture, narrow upper body and long legs is known as mental eminence.
<h3>
What are skeletal traits?</h3>
- The morphological diversity of the domestic dog serves as an example of how mammalian skeletal traits may evolve quickly and undergo significant modifications.
- Here, we employ principal component analysis to identify systems of features characterizing skeletal traits in a population of Portuguese Water Dogs.
- Through this research, phenotypic variation is divided into separate parts that can be utilized to analyze the genetic networks controlling intricate skeletal traits.
- We demonstrate that unlinked quantitative trait loci associated with these major components separately support both inverse correlations between structures and correlations within skeletal traits (for example, within the skull or among the bones of the limbs) (e.g., skull vs. limb bones).

The west Nile Virus is pathogen which caused the West Nile fever and encephalitis. The pathogen was introduced in 1999 in the Western Hemisphere and infected a major population in new york. It then expanded to 12 states and district of columbia. The major carrier of the pathogen was Avian and Mosquitoes species. In between 1999 to 2008, nearly 2500000 people were infected and nearly 1500 people died. Also there were thousands of cases of encephalitis or meningitis.
