Q: What causes cobalt chloride to turn pink? Read this paragraph and choose the correct option from the provided answers: A solution of cobalt chloride in water is pink due to the presence of the solvated Co 2+ ion. If sufficient HCl is added, the solution turns blue as the CoCl 4 2- ion forms. The reaction can be shifted back to the pink form if more water is added to the solution. Choices: - discussed 2 + ions - show 2 + ions - h20 + ions - co 2+ ions A:
co 2+ ions

Q: What are the organelles on which proteins are made during protein synthesis called? Read this paragraph and choose the correct option from the provided answers: Ribosomes are the organelles on which proteins are made during protein synthesis . Ribosomes are found throughout the cytosol of the cell and attached to the endoplasmic reticulum organelle. Ribosomes order amino acids using messenger RNA (mRNA) as a template in a process called translation. Ribosomes are made from complexes of ribosomal RNAs (rRNA) and proteins called ribonucleoproteins . Each ribosome is divided into two subunits. The smaller subunit binds to the mRNA pattern, while the larger subunit binds to the transfer RNA (tRNA) and the growing polypeptide chain. More about the ribosome will be discussed in the Cell Structures: Ribosomes (Advanced) concept. Choices: - mitochondria - lysosomes - fibroblasts - ribosomes A:
ribosomes
