The number of species on Earth tagged at 8.7 million as of 2011.
Solution:
Nitrogen is important because, it helps us grow crops, and it produces grass for animal. It comes from lightning and is named nitrogen fixation
By which free nitrogen (N2) is extracted from the atmosphere and converted (fixed) into nitrogen compounds which are plant nutrients (fertilizer). In nature, this process is carried out by certain bacteria (present in the root nodules of legumes such as beans and peas), blue-green algae, and the lightning flash.
Thus the Nitrogen form the atmosphere the biotic part to the ecosystem converted into the biotic part.
Answer:
Transcription & translation (Ans. A)
Explanation:
Prokaryotic organisms do not have membrane-bound organelles such as the nucleus, thus the process of transcription & translation occurs in the cytoplasm. Also because of the need for rapid life cycle, the mRNA molecules start to be made, & their ribosomes are ready to start making proteins more rapidly than Eukaryote, thus the process of the couple is quicker.
In eukaryotic organisms, transcription process start (happens) inside the nucleus of the cell and translation process can't start until the mRNA is transported out from the nucleus into the cytoplasm.
Answer:
both permeable
Explanation:
the cell wall is fully permable however the the cell membrane is selectively permable, there's little to no similarities between them, mainly differences as they're from two different cells completely
Answer:
D. they are usually dominant or recessive.
Explanation:
alleles are pairs of genes found on a particular spot a chromosome. If one is dominant over the other it give rise to a particular trait.
