Answer:
C
Explanation:
Meiosis create four genetically different haploid cells (this cells are gametes or sex cells)
The most important role of lipids is to store energy.
Answer:
it's D
Explanation:
When weather conditions are ideal, some ferns, algae, moss and even fungi, release spores into the air, often carried by the wind, by insects or birds until they land. Spores contain both male and female reproductive organs, which allows these plants to replicate themselves in a form of cloning.
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
Answer:
A. Water
Explanation:
Van Helmont concluded that most of the mass the plant gained had come from water, because that was the only thing that he had added to the pot. Van Helmont's experiment accounts for the "hydrate," or water, portion of the carbohydrate produced by photosynthesis.
