Water
This property of water explains why it floats when it freezes.
What is less dense?
Carbon is always bonded this many times
4
Hemoglobin is a protein that carries oxygen in the blood.
What is transport?
I am made out of a string of amino acids.
What is a protein?
A sunflower grows, uses energy, responds to sunlight, contains DNA, and reproduces. Alive or not alive?
Alive
Defined as the uneven distribution of charge
what is polar?
Plants take in carbon from the air in the form of this molecule.
What is CO2?
Lactase is a protein that chemically reacts with the sugar lactose - breaking it down.
What is an enzyme?
I am chitin - I make up the structure of many insects and mushrooms
What is a carbohydrate/polysaccharide?
A mule cannot reproduce, but we still consider it alive. Why doesn't its inability to reproduce disqualify it?
Not every individual must reproduce to be alive. Reproduction and evolution occur at the population level.
This property of water describes waters ability to stick to itself.
What is cohesion?
Carbon can bond repeatedly with itself to form these three types of structures.
What are chains, branches, and rings?
The sodium-potassium pump protein sits in the cell membrane and facilitates the movement of sodium and potassium ions in/out of the cell.
What is a transport protein?
I am generally made out of Carbon and Hydrogen chains.
What is a lipid?
A crystal can grow larger over time, but this alone does not make it alive. Explain why.
Growth by itself is not sufficient evidence of life. A crystal does not carry out the organized biological processes characteristic of living things
An animal basking in the sun is taking advantage of this property of water.
What is specific heat?
This element is always bound to carbon in an organic molecule.
What is hydrogen?
Insulin is a protein that tells the body that glucose is present.
What is signaling?
The building block of nucleic acids.
What are nucleotides?
Fire spreads, consumes fuel, releases energy, and can respond to its surroundings. Give one major reason we don't classify fire as alive.
It is not made of organized cells, does not contain inherited genetic instructions like DNA, and does not undergo biological reproduction/evolution.
This property of water allows for capillary action - water moving from the ground into the leaves of a plant.
What is adhesion?
Name at least four other elements commonly found bonded to carbon in biological molecules.
What are Hydrogen, Sulfur, Oxygen, Nitrogen, or Phosphorus.
Antibodies are a family of proteins that bind to foreign objects such as bacteria and viruses.
what is defense?
I am the product of transcription.
What is RNA?
Viruses contain genetic information and can evolve, but whether they are "alive" is controversial. What major characteristic of life do they lack when outside a host?
They cannot reproduce by themselves.
