<h2>B) is the correct option </h2>
Explanation:
- Collagen is a hard, insoluble, and fibrous protein that makes up one-third of the protein in the human body
- Molecules in collagen are packed together to form long and thin fibrils
- These act as supporting structures and anchor cells to each other and also give the skin strength and elasticity
- Collagen is the most abundant protein found in bones, tendons and muscle skin
- Collagen forms a scaffold to provide strength and structure
Because of these characteristics, genes associated with collagen is the best choice to base the phylogeny, rest all other options are not much diverse and specific to particular group of animal kingdom
Answer:
population mating structure and culture. hopefully I'm right.
Nitrogen Cycle steps:
N molecules breaking apart via nitrogen-fixing bacteria.
Animals ingest nitrogen in nitrate-containing food after plants use nitrogen-containing compounds.
The organic matter decays via decomposers
N2 is formed via denitrifying bacteria.
Explanation:
The nitrogen-fixing bacteria removes atmospheric nitrogen by fixing nitrogen through nitrification. The atmospheric nitrogen cannot be absorbed by plants and hence has to be converted into nitrates. This conversion takes place by nitrifying bacteria present in leguminous plants.
Animals (herbivores) consume the plants that have absorbed nitrogen/
When these animals die, decomposing bacteria acts on the dead organic matter, decomposition takes place through ammonification, converting the organic nitrates into ammonia
The nitrates are converted back again to nitrogen by the action of denitrifying bacteria.
The nitrogen thus formed is released to the atmosphere
