– 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[…]
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.
– 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 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.
Types of Electronic Bonds 1. Covalent bonds – 2 or more elements share electrons (ex: H2O) 2. Ionic bonds – strongest bonding. One element takes an electron from another molecule (ex: NaCl) 3. Hydrogen bonds – weakest form of bonding. Hydrogen atom interacts with an electronegative atom like nitrogen, oxygen, or fluorine
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.
x² + y² = 167 y = −3x Solve for x and y.
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?
The width of a rectangular floor is w feet. The length of the floor is 8 feet longer than its width. Write expressions for the area and perimeter of the floor in terms of w.
