Answer:
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
The best answer is C.
Chloroplasts are not found in all eukaryotic cells but only in plant cells. Animal cells are eukaryotic in nature but animals do not have chloroplasts in their cells because they do not engage in photosynthesis.
Photosynthesis is the process by which plants make their own food. Chloroplasts contain chlorophyll which is essential in t trapping sunlight from which supplies the energy for photosynthesis.
Animals do not make their own food like plants but eat ready made food so their cells lack mechanisms for food manufacture.
p53 protein is involved in control of cell cycle, which explains it role in tumor/ cancer suppressor
Photosynthesis is the process that plants use to make food, Which requires sun light, minerals from the soil, water, and carbon dioxide. (They turn carbon dioxide to oxygen).
Answer:
the three-base sequence of mRNA
Explanation:
Translation is the process of formation of proteins. Translation process is achieved with the help of ribosome, which links amino acids in the order defined by messenger RNA (mRNA), using RNA (tRNA) transfer molecules to hold amino acids and read three nucleotides at a time of the mRNA.
The three-base sequence are present in mRNA called codons or mRNA nucleotide triplet sequences are specific to a amino acids for proper function. For exmaple: AUG codon , specifies the amino acid methionine which acts as starts codon and initiate the process of translation.
Hence, during translation, the characteristic that represents the three base sequences of mRNA is related to the coding of single amino acid.
