Which of the following describes the function of ligaments?
A. Ligaments atach skeletal muscles to bone
B. Ligaments atach two bones
C. Ligaments atach bones to tendons
D. Ligaments atach skeletal muscles to tendons
Ligaments are tough bands of fibrous ssue that connect two bones together in a joint. They provide stability and support to the joint, prevenng excessive movement and helping to maintain proper alignment of the bones.
Therefore, the Correct Answer is B.

Q #1: Which of the following is an example of an exothermic reaction?
A. Melting ice
B. Burning wood
C. Cooking an egg
D. Dissolving sugar in water
Answer Explanation
Exothermic reactions are reactions that release energy in the form of heat, light, or sound. Burning wood is an example of an exothermic reaction because it releases heat and light. As the wood reacts with oxygen in the air, it undergoes a combustion reaction that releases energy in the form of heat and light. Melting ice is an endothermic reaction because it requires energy input to melt the solid ice into liquid water. Cooking an egg is a chemical reaction that involves denaturing the proteins in the egg, but it is not necessarily exothermic or endothermic. Dissolving sugar in water is also not an example of an exothermic reaction because it does not release energy in the form of heat, light, or sound.

Q #2: Which of the following types of RNA carries amino acids to the ribosome during protein synthesis?
A. Messenger RNA
B. Ribosomal RNA
C. Transfer RNA
D. Small nuclear RNA
Answer Explanation
Transfer RNA (tRNA) is a type of RNA molecule that carries amino acids to the ribosome during protein synthesis. Each tRNA molecule has a specific sequence of three nucleotides called an anticodon, which pairs with a complementary codon in the messenger RNA (mRNA) sequence. Each tRNA also carries a specific amino acid that corresponds to the codon it recognizes, allowing the ribosome to link the amino acids together in the correct order to form a protein.
In contrast, messenger RNA (mRNA) carries the genetic information from the DNA to the ribosome, where it serves as a template for protein synthesis. Ribosomal RNA (rRNA) is a component of the ribosome itself, where it helps to catalyze the formation of peptide bonds between amino acids. Small nuclear RNA (snRNA) is involved in splicing of pre-mRNA molecules during post-transcriptional processing.

A. Epithelial
B. Nervous
C. Connective
D. Exocrine glandular
Answer Explanation
Exocrine glandular is not one of the four primary ssue types found in the human body. The four primary ssue types are epithelial, nervous, connective, and muscle.
