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.

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.[…]

On Monday, Anna starts pouring water into a bucket at a rate of 4 cubic meters per second. Twenty seconds later, Bella starts pouring water into the same bucket at a rate of 5.5 cubic meters per second. How many seconds after Anna starts will the amount of water in the bucket equal or exceed[…]

Sarah drives 55 miles at 60mph. Then she drives for 6 hours at 48mph. Find her average rate.

In a physics problem, rate is inversely related to time for a given distance. When time is 4 hours, rate is 42 miles per hour. Find the rate when time is 6. Now, find the time when rate is 54 mph.

Two numbers sum to 18. The sum of their squares is 212. Find the smaller number.
