Terms
undefined, object
copy deck
- it has uracil in the place of thymine
- What is different about the bases of RNA?
- birth, growth, reproduction, and death
- What are the steps of an organisms life span?
- mitochondria
- Where does most Cellular Respiration occur?
- other living cells
- Today, where do all new living things come from?
- inside the nucleus
- Where are chromosomes found?
- the result of an abundance of water inside a cell that has a rigid cell wall
- What is turgor pressure?
- 4
- How many cells are present at the end of meiosis?
- sugar
- What is the most common energy source?
- aerobic respiration
- sugar + oxygen ----> carbon dioxide + water + energy
- a twisted ladder
- What does the DNA model look like
- the cells of plants, bacteria, and algae
- What organisms have cell walls?
- walls of dead plant cells
- What were the boxlike structures that Robert Hooke first named cells?
- metaphase
- the chromosomes align by their centromeres across the middle of the spindle
- asexual reproduction
- Is mitosis a form of asexual reproduction or sexual reproduction?
- telophase
- when sister chromatids reach the end of the spindle and the nucleus reforms
- Anton van Leeuwenhoek
- Who ground his own lenses to look at tiny organisms?
- interphase
- Genes are copied during this phase
- carbohydrates, proteins, nucleic acids, and lipids
- What 4 molecules did we discuss in Chapter 3?
- cytokinesis
- the cytoplasm divides and forms daughter cells
- a substance that affects the rate of a reaction but is not changed in the reaction
- What is a catalyst?
- fully formed and reproduce after their own kind
- According to the Scripture, how did God create all living creatures?
- anaphase
- during this phase the sister chromatids move to opposite ends of the spindle
- anaerobic respiration
- sugar ----> carbon dioxide + alcohol + energy or lactic acid
- prophase
- Nuclear membrane disappears; chromosomes coil; sister chromatids still attached before separated
- photosynthesis
- carbon dioxide + water + light energy ----> sugar + oxygen
- mitosis and cytokinesis
- What are the two stages of cell division?
- active transport
- In what type of transport is the cell's own energy used?
- all cells come from preexisting cells, all living things are made of cells and of the product of cells, and the functions of living things are performed by the cells they are made of
- What does the cell theory state?
- cellular boundaries, the cytoplasm, and the genetic material
- What are the 3 basic parts of a cell?
- sexual reproduction
- Is meiosis a form of asexual reproduction or sexual reproduction?
- movement, response, growth, and reproduction
- What are 4 life processes that require energy?
