Answer:
Requires additional labor
Explanation:
The pros are the positive points and cos are the negative points.
Cons of recycling bottle
Cons of recycling bottle will include all those factors which are affecting the nature or cost in some or the other way.
Out of all the given options, requires additional labor is a negative point as it points out the limitation of recycling of plastic. Plastic cannot be recycled if it requires extensively large labor force. Also large labor force will lead to higher cost.
Rest all other option are in support to the practice of plastic recycling.
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
The correct answer is: b. the removal of introns and alternative splicing of exons
Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail, RNA editing.
RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).
Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
Answer : A model that helps explain the results of Mendel's crosses is called a (Punnett square).
