Question

2 multiple choice 2 points identify the statement below: the bacteria are round. hypothesis quantitative observation conclusion qualitative observation 3 multiple choice 2 points what are the three main types of rna? coding rna, transfer rna, regulatory rna messenger rna, transfer rna, regulatory rna messenger rna, transfer rna, ribosomal rna coding rna, transfer rna, ribosomal rna 4 multiple choice 2 points what are the types of nucleic acids? proteins and lipids carbohydrates and nucleotides dna and rna enzymes and hormones

Explanation:

• For question 2, "The bacteria are round" describes a quality (shape) of bacteria, which is a qualitative observation. A hypothesis is a proposed explanation, a quantitative observation involves numbers, and a conclusion is a final judgment after analysis.
• For question 3, the three main types of RNA are messenger RNA (mRNA) which carries genetic information from DNA to ribosomes, transfer RNA (tRNA) which brings amino - acids to the ribosome during protein synthesis, and ribosomal RNA (rRNA) which is a component of ribosomes.
• For question 4, nucleic acids are macromolecules, and the two main types are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Proteins, lipids, carbohydrates, enzymes, and hormones are different types of biological molecules, and nucleotides are the building blocks of nucleic acids.

Answer:

1. qualitative observation
2. messenger RNA, transfer RNA, ribosomal RNA
3. DNA and RNA
