Biodiversity
What system do scientists use to name organisms?
Binomial nomenclature (genus + species)
What is the shape of a DNA molecule called?
Double helix
Which system is responsible for breaking down food into nutrients?
Digestive system
What pigment allows plants to capture light energy for photosynthesis?
Chlorophyll
What is Miss Oliveira's heritage?
Portuguese
What are the three domains of life?
Bacteria, Archaea, Eukarya
What are the base-pairing rules of DNA?
A pairs with T; C pairs with G
What is the function of alveoli in the respiratory system?
Gas exchange (oxygen in, carbon dioxide out)
What are the two main types of vascular tissue in plants and their functions?
Xylem (transports water/minerals) and Phloem (transports sugars/food).
What teams does Coach Kevin coach?
Aerials, Girls/Boys Basketball
Name two differences between prokaryotic and eukaryotic cells.
Prokaryotes lack a nucleus and membrane-bound organelles; eukaryotes have both
What is the difference between mitosis and meiosis?
Mitosis = produces two identical diploid cells for growth/repair; Meiosis = produces four genetically unique haploid gametes
How do the circulatory and respiratory systems work together to maintain homeostasis?
Respiratory system supplies oxygen to blood; circulatory system delivers oxygen and removes carbon dioxide from cells.
How do guard cells control the opening and closing of stomata?
They swell with water to open the stomata and shrink (lose water) to close it.
How many siblings does Miss Oliveira have?
One sister
Which kingdom contains organisms that are eukaryotic, multicellular, and autotrophic?
Plants
In a monohybrid cross Tt × Tt, what is the genotypic ratio of the offspring?
1 TT : 2 Tt : 1 tt
Trace the path of blood through the heart starting from the right atrium
Right atrium → right ventricle → lungs → left atrium → left ventricle → body.
Compare phototropism and gravitropism in plants.
Phototropism = growth in response to light; Gravitropism = growth in response to gravity.
When did the Toronto Maple Leafs win their last Stanley Cup?
1967
Explain how phylogenetic trees show evolutionary relationships among species.
They show branching patterns based on common ancestry; closer branches = more recent common ancestors.
Explain how crossing over during meiosis increases genetic variation
Homologous chromosomes exchange DNA segments in prophase I, producing new allele combinations.
Explain how the digestive, circulatory, and excretory systems are interconnected in maintaining homeostasis
Digestive system breaks down food into nutrients → circulatory system transports nutrients/wastes → excretory system filters blood and removes waste, maintaining balance.
Explain the process of transpiration and how it helps move water through a plant.
Water evaporates from leaves → creates negative pressure → pulls water upward through xylem (transpiration pull).
Who is the greatest soccer player of all time?
Cristiano Ronaldo SIUUUUUUUU
