tRNA and mRNA can leave the nucleus.
Explanation:
tRNA, when mature and correct, can leave the nucleus and enter the cytoplasm. mRNA can leave the nucleus through pores in the nuclear membrane. However, DNA cannot leave the nucleus, it has to be transcribed into RNA.
The correct statement describing environmental consequence of unsealed Landfills is : ( A ) Landfills can produce carbon dioxide that leak into the atmosphere
A landfill is composed of 4 essential components and some are ;
- bottom linear
- hydrogeologic component and
- A cover ( seal )
Given that a landfill constitutes of about 40 to 60 percent of C0₂ the environmental consequence of not providing a proper seal for the landfill will be the leakage of C0₂ into the atmosphere. while
The release of Heavy metals as leach ate into the surrounding can be controlled with the provision of a system in the landfill, materials in landfill undergo decomposition for a long period of time.
Hence we can conclude that Landfills can produce carbon dioxide that leak into the atmosphere.

Answer:
Biological: 2) not applicable for extinct species.
Morphological: 3) relies on similarities of structures. The morphology studies the structures.
Phylogenetic: based in the history of the specie
Morphological and phylogenetic : 1) acommodates asexual reproduction and 5) species acceptance criteria can be subjetive
all three: 4) used by scientists in classification
Calcium chloride is a salt, which is used in household and in industries. The calcium chloride is an ionic compound which can be split in ionic form such as one cation (Ca2+) and two anions (Cl-). Therefore, the cation in the CaCl compounds is Ca2+ ions.
