Scientific Terms to Know for Standardized Tests
– Peduncle: the stalk of a flower – Receptacle: the part of a flower stalk where the parts of the flower are attached – Sepal: the outer parts of the flower (often green and leaf-like) that enclose a developing bud – Stamen: the pollen producing part of a flower, usually with a slender filament supporting[…]
Know the Parts of the Cell
– Cell wall: surrounds/protects cell (only in plant cells) – Cell membrane: controls movement of materials into and out of the cell (active/passive transport) – Cytoplasm: watery area of movement – Mitochondria: produces/supplies energy – Chloroplasts: contain chlorophyll (capture sunlight) [only in plants] – Vacuoles: store food/water/chemicals – Nucleus: regulars.controls cell activities – Nuclear membrane:[…]
Facts About the Cell – ACT Science
What is mitosis? Mitosis is the process of cell division. One cell becomes two cells with full chromosomal identity. Stages of mitosis: 1. Prophase 2. Metaphase 3. Anaphase 4. Telephase Cytokinesis begins in anaphase or telephase. Cytokinesis is the division of the cytoplasm into 2 new cells.
Chem + Bio for ACT Science Section
– Higher temperatures will (usually) increase reaction rate, colder temperatures will (usually) decrease reaction rate. – Amoebas: unicellular, have a nucleus, lack cell wall – Trophic level: the higher in a food chain an organism is, the higher its trophic level is. Producers have a lower trophic level than consumers. – Accuracy vs. Precision in[…]
DNA Info for Science Section on Standardized Tests
– DNA undergoes transcription to become RNA. RNA undergoes translation to become protein. – Ribosomes contain RNA – Proteins are large molecules with smaller amino acids in them. – The nucleus of a cell contains chromosomes. The chromosomes have DNA wrapped in proteins.
The Structure of a Molecule – ACT Prep
The center of an atom is a nucleus. In the nucleus, there are 2 subatomic particles: protons (positive charge) and neutrons (neutral charge). Outside of the nucleus are electrons. The energy of an electron is in shells. An atom is a single nucleus with a positive charge surrounded by a cloud of negatively charged electrons.[…]
Practice Math Problems for ACT + SAT
Sally is staying at a hotel that charges $88.50 per night plus tax. A 6% tax is applied to the room rate, and an additional onetime untaxed fee of $7.00 is charged by the hotel. Write an expression for Sally’s total charge, in dollars, for staying x nights.
SAT & ACT Math Practice
The function h is defined by h(x) = 6x³ + 9x² + 3cx + 24, where c is a constant. If (-4, 0) is one of the x-intercepts of h, what is the value of c?
SAT/ACT Math Practice
