Which TWO descriptions of plants explain how they contributed to the carbon cycle?
denpristay [2]

Plants stored carbon in their tissues to use as energy and plants took in carbon dioxide and released oxygen through photosynthesis. Thus, the correct option is A and D.

<h3>What is carbon cycle?</h3>

The carbon cycle is the ongoing process through which carbon atoms move back and forth between the atmosphere and the Earth. The amount of carbon in this system does not fluctuate because our planet and its atmosphere are a closed environment. The location of the carbon, whether it is on Earth or in the atmosphere, is continually changing.

Plants use photosynthesis to transport carbon from the atmosphere into the biosphere and move it up the food chain. They make sugar molecules by chemically combining carbon dioxide with oxygen and hydrogen from water using solar energy.

Ribosomes provide the scaffolding on which tRNAs interact with mRNA during translation of an mRNA sequence to a chain of amino a
vampirchik [111]

Answer:

a. True

Explanation:

Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
