Answer:
It is essential for all living things. Fixation: In order for organisms to use atmospheric nitrogen (N2), it must be “fixed” or converted into ammonia (NH3).
Explanation:
Answer:
Explanation:
The rate of pollination in the field (near the pond with no fish) will decrease exponentially. Because, as the fish population is removed from that ecosystem, the population of dragonflies and larva increases without check because, fish feeds on the dragonflies larva and kept there population in check. Due to this, the population of bees and other pollinators population decline becuase, they are major food source of dragonflies.
Honeybees are the keystone species because it's absence will lead to major changes in the ecosystem.
Answer:
Results are validated when other scientists performs the same experiment and conclude with the same result.
Explanation:
Experimental evidence gives confirmation especially in science.Scientists starts an experiment by following some protocols such as observation,hypothesis,collection of data literature review,methodology,Experiments (trial and tests) finally results and discussion.Results are validated as experimental evidence. Eventually come to a conclusion.
<span>The nucleolus is the structure within the nucleus of eukaryotic cells. It consists of RNA, DNA, and proteins. The nucleolus is involved in ribosome biogenesis which results in the synthesis of ribosomes. Ribosomal RNA (rRNA) is transcribed from DNA in the nucleolus. rRNA is processed into three mature RNAs and together with proteins form ribosomal subunits. After subunits form the ribosomes, they are transported out of the nucleus to the cytoplasm where they take place in translation.</span>
