RNA molecules attach to codons when the ribosome reaches the start codon.
Explanation:
The start codon initiates translation of the mRNA by the ribosome into a polypeptide. When the ribosome finds the start codon, it attaches to the mRNA and the first amino acid, methionine, is recruited. The ribosome then continues translating the rest of the mRNA until it encounters a stop codon that initiates the ‘knocking off of the ribosome from the mRNA.

Answer:
B) realized niche
Explanation:
The ecological niche refers to all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species. The term ecological niche refers to the fundamental niche or the realized niche.
- The fundamental niche refers<u> only</u> to factors or physical conditions under which a species can live and survive in the <u>absence of any interaction with other species.
</u>
- The realized niche refers to the restricted conditions in which a species can live and survive as a result of <u>environmental conditions and the interaction with other species</u><u>.
</u>
When an inferior competitor is excluded by the superior competitor, this is known as competitive exclusion. This occurs when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective or realized niche of the dominant species completely occupies the fundamental niche of the inferior competitor.
In the exposed example the organism is able to occupy a niche in the presence of competitors, which is the clue for us to classify this niche as a realized niche. The organism needs to interact in a certain way with its competitors. There is an interaction between taxonomic groups, or between individuals.

Let's go back to "Darwin's" evolution theory. mice can be smarter than the average hawk, they are fast, have underground protection from cold,heat, rain,ECT..and they scavenge during p.m. hours, not all hawks are nocturnal, that's why owls are nocturnal. This cycle ensures enough food source for all predators. A hawk can consume at least 6 mice per day/night. rodents are natural prey for all preditors., even coyote. hope this helps, plus mice reproduce quickly compared to preditors.
hope this helps..
Answer:
Gap Junctions.
Explanation:
Gap junctions are intercellular channels that allows the cell transfer of molecules, ions and electric impulses.
They are connected through the protein channel and are found in many parts of vertebrate and invertebrate nervous systems.
Its most important function is to control the activities of adjacent cells.
