Theories
Charles Darwin proposed which theory?
Name 3 organ systems of the body.
They can be: integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems.
Name the two types of cells.
Prokaryotic and Eukaryotic cells
Process used by plants and other organisms to convert light energy into chemical energy.
Photosynthesis
This is the reason giant alga is an exception to the cell theory
it lacks subdivision into separate cells
According to the cell theory, the genetic code is?
Universal
What are the tiny air sacs in the lungs called?
Aleveoli
Name of the double layer of phospholipids that makes up a plasma membrane.
Phospholipid bilayer
Name the two types of cellular respiration.
Aerobic and anaerobic respiration.
Are viruses living things? Explain.
Viruses are not living things, this is because they depend on cells in order to live.
The origin of eukaryotic cells can be explained by which theory?
Endosymbiotic theory
Explain the difference between arteries and veins when carrying the blood.
Arteries carry oxygenated blood to all body parts, whereas, veins carry the deoxygenated blood to the heart.
State the organelle responsible of regulating the entrance and exit of molecules into and out of the cell (transport across the cell).
Plasma membrane
What are the reactants of photosynthesis?
Water and carbon dioxide.
A group of cells with a common structure and function.
Tissue
Name the three statements of the Cell Theory.
1. All living things are composed of one or more cells
2. The cell is the basic unit of life
3. New cells arise from existing cells.
What does the liver do to help digestion?
Bile helps to break down fats, preparing them for further digestion and absorption. All of the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates nutrients for the body to use.
State three organelles only found on plant cells.
A cell wall, a large central vacuole, and plastids such as chloroplasts.
This wavelength is the shortest wavelength absorbed by green plants
what is blue
These trap long wave radiation from earths surface
Greenhouse gases
Explain what Pasteur's experiment about the spontaneous generation was about?
Pasteur invented the swan-necked flask to create an environment known not to grow microorganisms. After sterilizing a nutrient broth in these flasks, he removed the swan necks of the controls. Microorganisms grew only in the controls, refuting spontaneous generation.
This seals the blood clot, final step
Fibrin
Difference between the Rough endoplasmic reticulum and the Smooth endoplasmic reticulum.
Rough endoplasmic reticulum:Has ribosomes attached and creates proteins.
Smooth endoplasmic reticulum:No ribosomes attached and makes phospholipids.
Explain the difference between anabolism and catabolism.
Anabolism creates molecules the body needs for functionality and it uses energy in the process. Catabolism, on the other hand, breaks down complex molecules and releases energy which is available for the body to use
An inherited characteristic that enables an organism to survive and reproduce successfully in its environment is called?
Adaptation
