Answer:
Lungs.
Explanation:
Lungs are the organs that are responsible for gaseous exchange in humans. The lungs absorb oxygen from the air that is required for the process of respiration while on the other hand, carbon dioxide is transferred from the cells to the lungs through blood because carbondioxide gas is a waste material that is produced during respiration so it can be removed from the body with the help of lungs..

Answer:
E2F transcription factors
Explanation:
The E2F transcription factors (TFs) encode intracellular factors associated with the control of the cell cycle. E2F are TFs that bind to promoter consensus sequences in order to activate transcription. These TFs control the expression of target genes involved in cell proliferation including, among others, genes for DNA replication and mitotic activation. Moreover, the E2F proteins also may act as a link between cell fate and the cell cycle. The retinoblastoma (Rb) is a protein that modulates the activity of the E2F family of TFs, and it has been shown that the Rb/E2F pathway is a key molecular mechanism associated with cell proliferation.

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.
