Overfishing is when humans overfish an area of fish, and cause it’s population to decline, it is not sustainable because this can make species extinct in certain regions of the ocean.
<span>The question is 'organisms interact with each other and their environment in different ways. What is an organism's niche. A particular organism ecological niche is defined as that organisms roles in its particular environment. It covers all the ways in which the organism affect its physical environment and the other organisms that are cohabiting the environment with it, that is, the function of the organism in its environment and its interrelationships with all the biotic and abiotic factors present in its environment.</span>
This can be done through the Transcription and Translation process.
Long story short: DNA -> messenger RNA (mRNA) -> amino acids -> polypeptide chain -> protein
Step 1: Transcription
1) DNA loop is open
2) RNA polymerase (enzyme in nucleus) catalyze reaction of “unzipping” DNA
3) free RNA nucleotides in nucleus will be added to that strand of DNA
4) messenger RNA moves across nuclear membrane to cytoplasm (our nucleus)
Step 2: Translation
1) messenger RNA attaches to ribosome
2) mRNA determines which amino acid to place on protein
3) uses codons (triplet) on mRNA. Codon on mRNA and anticodon on tRNA have to match, which places true amino acid in ribosome, then it detached and finds another amino acid in cytoplasm.
4) “AUG” starts translation, and keeps going until reaching “stop codon”.
5) completed polypeptide chain results to protein being synthesized
Your teacher should explain this process more in depth hopefully
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds. Their paths typically have a meandering shape.
