Since the two species co-inhabit the same habitat, habitat isolation can be disregarded as a factor keeping the two species separate. There are however some other broad categories of mechanisms for <span>reproductive isolation. One is behaviour. Many birds in particular have very specific mating rituals, including mating dances, particular bird song, the development of specific mating plumage, the release of specific pheromones and the building of a particular nest structure. Another broad category is mechanical isolation. You will find that the genital organs of particular species are very specific, and preclude other close species from successfully mating. Another broad category is gametic isolation. For most species combinations, it is not possible for the gametes to fuse successfully to form a hybrid. If hybrid games do fuse, in many cases, the hybrids are sterile, such as mules for example.     </span>

Lina20 [59]

Answer:option C= mRNA

Explanation:

MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.

The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.

mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.

valina [46]

Answer:

Mitochondria is known as the powerhouse of the cell as it provides energy to the cell for performing different functions.

If a toxin causes pore in the inner membrane of the mitochondria and  increases the permeability of the mitochondrial membranes. The permeability of mitochondrial membranes leads to mitochondrial swelling and causes cell death through necrosis and apoptosis.
