Characteristics of Life
Why are viruses considered non-living?
What is they must use the cell from a host to divide and reproduce
What does the human body do to maintain homeostasis when it is cold outside?
What is shiver
What process takes the sun's energy, splits water and makes oxygen, and takes in Carbon Dioxide and makes carbohydrates?
What is photosynthesis
What are the pairs of bases in the DNA molecule?
What is Guanine/Cytosine, Adenine/Thymine
How much energy is kept as energy moves up the food chain?
10%
What is the function of the following macromolecules?
a. Carbohydrate
b. Lipid
What is
a. Provide quick energy
b. Store energy
A red blood cell is specialized to carry oxygen; which is needed for the life of the cells. Which organelle does it not contain to make more room for oxygen?
a. Ribosome
b. Nucleus
C. Golgi Apparatus
What is nucleus
What process must take in glucose and oxygen, and then releases carbon dioxide and water as its product?
Cellular respiration
What are the base pairs of RNA?
What is Adenine/Uracil, Guanine/cytosine
What will happen if nitrogen fixing bacteria are removed from an area
Plant growth will slow or stop
What two parts are always included in a good experiment
What is a control and a variable
This type of transport goes against the concentration gradient and uses energy
What is Active Transport
Why does the Kreb's Cycle (Citric Acid Cycle) and Electron Transport Chain release so much more energy than Glycolysis?
What is oxygen is added
What is the product of DNA Replication?
Two identical DNA molecules to be used in the new cells in cell division
If a trait helps an organism survive in its environment, what is it called?
An adaptation
What is the function of a control in an experiment?
To provide a baseline to gauge the effect of a variable
If a cell has a 20% amount of solutes in it, and is in a solution of 40% solutes, which way will the water from inside the cell move?
To the outside of the cell
Would aerobic or anaerobic respiration be more efficient and why?
Aerobic- oxygen
What are the stages in RNA Protein Synthesis?
What is Transcription, Translation, Protein synthesis
Organisms with homologous structures are said to have an...
Common ancestor
What specialized organelle would be missing from a nerve cell, and why?
a. nucleus
b. mitochondria
c. centriole
What is a centriole, because they play a part in cell division. A nerve cell divides the least frequently of any other cell in the body
A cell is placed into a solution of distilled water; the amount of solutes in the solution is much lower than the cell. What will the end result of the cell be?
What is it will swell and possibly burst
What causes the burn we feel after running a long time, especially in sports?
Lactic acid
Where does DNA Transcription and RNA Translation and Protein Synthesis take place in the cell?
What is:
Transcription:Nucleus
Translation: Cytoplasm/Ribosome
Protein synthesis: On the ribosome
If nature selects a trait because it gives an advantage in its environment, the method of selection is called...
Natural selection
