Living Things
What are the 5 basic needs of living things?
Food, water, energy, certain gases and space.
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulfur.
According to Cell Theory, where do all new cells come from?
Preexisting cells.
What does ATP stand for?
Adenosine Triphosphate
What does PMAT stand for?
Prophase, Metaphase, Anaphase, Telophase
A person begins to sweat when their body gets too hot. What response of living things does this demonstrate?
Homeostasis
Which major organic compound includes fats and oils?
Lipids
Which cell structure acts as the control center of the cell and contains DNA?
The nucleus.
What is the chemical formula for glucose?
C6 H12 O6
During which phase of mitosis do the chromosomes line up in the middle of the cell?
Metaphase
What is the difference between homeostasis and metabolism?
Homeostasis is maintaining stable internal conditions. Metabolism is all the chemical activities taking place in an organism.
Which major organic compound contains genetic information?
Nucleic acids.
What are the three parts of a DNA nucleotide?
A sugar, a phosphate and a nitrogen base.
What is the difference between aerobic and anaerobic respiration?
Aerobic respiration uses oxygen; anaerobic respiration does not.
During which phase of mitosis do the chromosome copies move apart towards opposite sides of the cell?
Anaphase
A plant bends toward a light source. Which characteristic of living things does this demonstrate?
Responding to the environment.
Which major organic compound helps build and repair cells and tssues?
In DNA, which nitrogen base pairs with cytosine?
Guanine
Water moves across a cell membrane. What process is occuring?
Osmosis
During which phase of mitosis do two new nuclei begin to form?
Telophase
What is the difference between science and technology?
Science helps us understand the natural world; technology applies what scientists learn.
What major organic compound is body's main source of energy?
Carbohydrates
If one DNA strand has the sequence A-C-G-T, what is the complementary DNA sequence?
T-G-C-A
A cell uses ATP to move particles from an area of low concentration to high concentration. What type of transport is occurrring?
Active transport
One parent cell completes mitosis. How many daughter cells are produced, and how does their chromosome number compare with the parent cell?
Two daughter cells are produced, and each has the same chromosome number as the parent cell.
