Smallest stable unit of matter in creation
Two or more atoms linked together to make a substance with unique properties
The process where a plant uses sunlight and certain chemicals to make its own food
The process where a living organism takes energy from its surroundings and uses it to sustain itself, develop, and grow
Special structures or chemicals that allow living organisms to sense the conditions of their surroundings
The smallest unit of life in Creation
The four criteria for life
1) all life forms contain DNA; 2) all life forms take energy from their surroundings and convert it to energy to help them live; 3) all life forms can sense changes in their surroundings and respond to them; 4) all life forms reproduce
Compared to other molecules, is DNA big or small?
Does DNA store its information more efficiently or less efficiently than a computer?
DNA is made up of two basic parts: the backbone and the nucleotides. A) Which part stores the information? B) Which part forms the double helix structure?
A) Nucleotides; B) Backbone
Which nucleotide will link to adenine? Which will link to cystosince?
adenine links to thymine, and cystosine links to guanine
One half of a portion of DNA has the following sequence: cystosine, guanine, adenine, guanine, thymine, thymine. What is the sequence of nucleotides on the other half of this portion?
Guanine, cystosine, thymine, cystosine, adenine, adenine
One half of a portion of DNA has the following sequence: thymine, guanine, cystosine, adenine, thymine, guanine. What is the sequence of nucleotides on the other half of this portion?
adenine, cystosine, guanine, thyamine, adenine, cystosine
What is the name of the chemical that plants make for food?
What is the name of the chemical that plants store their food as?
What is a biosphere?
A living system that is isolated from its surroundings but continues to live and grow
Metabolism requires food and something else. What is that something else?
Metabolism produces energy, carbon dioxide, and what else?
An organism's receptors no longer work. Which one of the 4 criteria of life will the organism not be able to perform?
Number 3 - To sense changes in their surroundings and respond to them
Consider the difference between a shark and an anchovy. Both are fish. The first is a fierce hunter that rarely is eaten by another animal. The second is a major source of food for many other fish in the sea. Which would you expect to have more babies: two shark parents or two anchovy parents?
Two anchovy parents (because they are eaten more quickly and need to replace themselves)
Every once in a while, a female cat will be born sterile. This means that the cat cannot have kittens. Does this mean that the cat is not alive, since it cannot reproduce?
No! (It's alive and has reproduction organs, but they just don't function correctly.)
Is the population of people on this earth becoming a problem?
NO! It will stay slow and steady.
How many kinds of cells are there?
Three (plant cell, animal cell, and bacteria)
Where is DNA stored?
In the nucleus
If a scientist uses a microscope to examine a cell from a mouse, a cell from a leaf, and a cell from a cat, how many different basic kinds of cells will she have?
Two (plant and animal)
How is information stored in DNA?
In a coded series of the four nucleotides (adenine, thymine, cystosine, and guanine)
What does DNA provide to a living organism?
Information necessary to take lifeless chemicals and turn them into a living system
