Answer:
It is a season in which fish reproduce.
Explanation:
Piracema is not name of the fish, its the name given to the period of the year when fish reproduce within the Paraguay River. The season of reproduction started from October till March, during this period the fish swim upstream to lay their eggs and reproduce. Thus the season is critical for the maintenance of fish populations in the waters of the rivers and lakes. Brazilian states prohibit fishing during this period in order to maintain fish population in the river.
It does take several years yes.... However this is if the disease progresses far enough. The patient however could die from trauma or other such things as the dementia may alter their alert and awareness.
Answer:
Ammonia
Explanation:
Nitrogen fixing bacteria turn nitrogen into ammonia and plants can absorb it
Hope this helps :)
Answer: start codon AUG of mRNA
Explanation:
The ribosomal assembly consist of two receptor sites, the P and A sites. The P site carries the peptidyl-tRNA, the growing peptide chain while the A site carries the new incoming tRNA with the amino acid to be added next.
The mRNA signal the initiation process with it start codon AUG. Because the start codon AUG codes for the amino acid methionine. A tRNA attach to methionine (tRNA-Met) binds to the start codon. The anti-codon UAC of the met-tRNA is correctly base pairing with the AUG codon on mRNA.
Answer: Evidence of a natural selection in action.
Explanation: Wallace and Darwin both observed similar patterns in other organisms and they independently developed the same explanation for how and why these changes could take place. However, Darwin called this mechanism natural selection. Natural selection, is also known as "survival of the fittest." is more prolific reproduction of indivduals with favorable traits that survive environmental change just because of those traits. This is what leads to evolutionary change. Darwin believed that the finches because the finches had different beak sizes among species that they came from the mainland species.
