Themes of Biology
Maintain a stable internal environment
What is homeostasis?
The repeating sequence of cellular growth and division
What is a cell cycle?
An enzyme ____________ the ___________ energy
What is lowers; activiation
This Protects DNA and act like a mayor of a city.
What is the nucleus?
This is when energy is required to move materials through a cell membrane.
What is active transport?
Make an observation, ask a question, form a hypothesis, test the prediction, draw a conclusion, retest experiment
What are the steps to the scientific method?
A sugar, a base and a phosphate group
What is are nucleotides?
Centromeres
What are the structures that hold chromosomes together?
An enzyme is known as
What is a biological catalyst?
This acts the post office and will process and sort proteins to be shipped.
What is the Golgi apparatus/body?
This causes the cell to shrivel up.
What is hypertonic?
The variable that is being observed; located on the Y-axis.
What is the dependent variable?
mutations in the cell cycle.
What is uncontrolled growth/cancer?
The starting materials for chemical reactions are called _________________, while the new substances that are formed are called _______________.
What are reactants; products?
This provides energy to the cells like FPL provide electricity to your house.
What is mitochondria?
This is when the cell membrane forms around another substance, to bring it inside the cell. For example, how the amoeba gets its food.
What is endocytosis?
When a molecule has a negative charge on one end and a positive charge on the opposite end.
What is a polar molecule?
This is the third phase of the cell cycle that occurs after mitosis.
What is cytokinesis?
This is when cells are programmed to die at a predetermined time in their life cycle or after a certain number of cell divisions.
What is apoptosis?
The energy needed to start a chemical reaction is called ______________ ___________.
What is activation energy?
These are the four things that Prokaryotic and Eukaryotic Cells have in common.
What are cell membrane, ribosomes, cytoplasm, and genetic material?
This type of passive transport ensures that every cell is oxygenated and goes from a high to low concentration.
what is diffusion?
Water molecules are able to move from the roots of a plant to the leaves.
What is adhesion and cohesion due to capillary action?
Cell growth, DNA synthesis, and preparation for mitosis occurs during this phase.
What is interphase?
The molecule on which an enzyme acts is called the ________________.
What is the substrate?
This organelle is responsible for protein synthesis.
What is ribosome?
In order to get rid of waste in the cell, the cell must go through this process.
What is exocytosis?
