BSP 1-2 MIDTERM EXAMINATION - GENERAL ZOOLOGY

Which branch of Biology focuses on the study of animals?

• Botany

• Zoology

• Microbiology

• Ecology

You are labeling a cell diagram and need to identify the organelle that forms a network of membranes for protein transport. You label the:

• Vesicles

• Rough endoplasmic reticulum

• Smooth endoplasmic reticulum

• Ribosome

Evaluate why errors in meiosis are more harmful than errors in mitosis.

• Because meiosis errors affect gametes and can be inherited

• Because mitosis errors occur only in plants

• Because meiosis doesn’t repair DNA

• Because mitosis affects genetic variation

What key difference distinguishes connective tissue from epithelial tissue?

• Connective tissue has tightly packed cells

• Connective tissue has abundant extracellular matrix

• Epithelial tissue contains more fibers

• Epithelial tissue is rich in blood vessels

The epithelial tissue that is a single layer of flat cells is called:

• Simple cuboidal

• Simple columnar

• Simple squamous

• Stratified squamous

During which stage of mitosis do the sister chromatids separate and move to opposite poles?

• Telophase

• Prophase

• Anaphase

• Metaphase

What is the role of the Golgi apparatus?

• Assembling ribosomes

• Packaging and distributing proteins

• Generating energy

• Breaking down waste

Which of the following best explains how Aristotle and Linnaeus both contributed to zoology?

• Both created theories of evolution

• Both developed classification systems for animals

• Both rejected taxonomy

• Both studied the anatomy of humans only

A scientist studies a cell with extensive rough endoplasmic reticulum. This suggests that the cell’s main function is:

• Energy production

• Protein synthesis

• Waste breakdown

• Lipid storage

Which structure controls the activities of the cell and contains genetic material?

• Cytoplasm

• Nucleus

• Ribosome

• Golgi apparatus
