BSC 2085 WEATHERS LTIPLE CHOICE. Choose the one alternative that best completes the statement or answer tion. 1) Which of the following structures function in holding organelles in place, maintaining 1 cell shape and rigidity, and directing organelle movement? A) Cilia B) Centrioles C) Flagella D) Golgi apparatus E) Microtubules 2) The building blocks that form the DNA double helix are called A) steroid bases. B) nucleoli C) nitrogenous acids. D) nucleotides. E) muclear pores. 3) The smallest structural unit that exhibits the characteristics of living things is A) an individual. B) a cell C) tissue. D) a system E) an organ. 4) Which anatomical term describes the wrist region? A) Carpal B) Tarsal C) Digital D) Perineal E) O?ecraal are responsible for synthesizing most of a human body cell's AT. 5) Thea A) nucleoli B) ribosomesExplanation / Answer
1) Cilia and flagella help in locomotion. Centrioles help in cell division. Golgi apparatus helps in secretion and sorting of proteins. Microtubules help in holding organelles in place, maintaining cell shape and rigidity, and directing organelle movement. So, the answer for this question is microtubules (option E).
2) The building blocks that form the double helix of DNA are called as nucleotides (option D). Nucleoli is seen inside the nucleus. Steroid bases are required for hormone synthesis and nuclear pores are seen in nuclear membrane.
3) The smallest structural unit that exhibits characteristics of living things is a cell (option B). Cells combine together to form tissues. Tissues together form organs. Several organs constitute organ systems.
4) The anatomical term that describes the wrist region is carpal (option A). Tarsal represents foot region. Digital represents finger region.
