TEAS 2022 SCIENCE SECTION Question Fully solved 2024/2025.

Biological Hierarchy - correct answer chemicals (smallest most specific) -- cells -- tissues -- organs -- organ system -- organism (biggest most broad) key macromolecules for living things - correct answer - carbohydrates - proteins - lipids - nucleic acids Four basic types of cells - correct answer - epithelial (skin) cells - connective - nervous - muscular tissues - correct answer cells with the same function that are collected into larger groups. can form organs organs - correct answer carry out a single task. ex: lungs (an organ) have to deliver oxygen to the bloodstream organ system - correct answer organs work together in an organ system, which performs coordinated large scale functions. ex: in the nervous system, nerves and the brain work together to collect and process information. Nervous System sends signals to musculoskeletal system to create movement. Basic parts of a cell - correct answer - nucleus - plasma membrane - cytoplasm (which contains organelles) organelles - correct answer - cell wall - chloroplasts - cytoskeleton - golgi apparatus - lysosomes - ribosomes - mitochondria - nucleus - plasma membrane - Rough endoplasmic reticulum (rough er) - smooth endoplasmic reticulum (smooth er) -vacuoles cell wall - correct answer (an organelle) provides structural support and protection for the cell Chloroplast - correct answer (an organelle) uses photosynthesis to produce ATP (energy) and other sugars Cytoskeleton - correct answer (an organelle) helps in the transferring of materials and movements of whole cells Golgi apparatus - correct answer (an organelle) PROCESSES proteins Lysosomes - correct answer (an organelle) helps in the digestion and recycling of old cell materials Mitochondria - correct answer (an organelle) makes ATP so that the body can function. aka the powerhouse of the cell Nucleus - correct answer (an organelle) holds all genetic information (DNA), chromosomes, and builds ribosomes. Plasma membrane - correct answer (an organelle) maintains the cells environment (homeostasis) through the process of selective permeability Ribosomes - correct answer (an organelle) MAKES proteins Rough Endoplasmic Reticulum (Rough ER) - correct answer (an organelle) processes PROTEINS in the cell
