characteristics of life
What is a unicellular organism?
what are organisms made of one cell
What is the most basic unit of matter?
What is an atom?
What does the pH scale range from?
What is a range of 1 to 14
What are the four types of macromolecules?
What are lipids, nucleic acid, proteins, and carbohydrates
What is the monomer of carbohydrates?
What are monosaccharides?
How do organisms maintain homeostasis when they are hot or cold?
What is shivering when cold and sweating when hot?
What are the three types of subatomic particles?
What are electrons, neutrons, and protons?
What is the pH of water?
What is a pH level of 7
Why are the four major macromolecules considered organic?
Why do they they all have a carbon backbone
What are examples of common carbohydrates?
glycogen, cellulose, starches, and sugars
What is the difference between sexual and asexual reproduction?
Sexual reproduction mixes genetic information from two different organisms to create offspring and asexual reproduction produces an offspring with genetic information identical to the parent
What does the atomic number of an element on the periodic table indicate?
What is the number of protons in the element
What does a pH lower than seven indicate about a solution?
What is an indication that the solution is acidic
Why is carbon involved in all organic life?
Why does carbon have the ability to form four covalent bonds
What is the difference between a monosaccharide and a disaccharide?
Why are monosaccharides the monomer of carbohydrates and disaccharides the combination of two monosaccharides?
What is the importance of mutations to evolution?
Why do mutations give rise to adaptations giving, organisms an advantage over their peers in survival, and making them more likely to pass on their traits?
How do you calculate the number of neutrons in an isotope of a certain element, by using the numbers provided on the periodic table?
What is subtracting the atomic mass by the atomic number?
What are molecules which help to maintain an organism's internal pH?
What are buffers?
What is the difference between polymers and monomers?
Why are monomers small individual molecules, while polymers of a chain of a molecule stringed together
What is the difference between disaccharides and polysaccharides?
Why are disaccharides the combination of two monosaccharides and polysaccharides the combination of more than two
What is the singular cell homes develop from
what is a zygote
What is the difference between covalent and ionic bonds?
What is sharing electrons between two atoms in comparison to exchanging electrons?
What is the relationship between the pH and pOH scale?
What is an inversely proportional relationship
Why are lipids not polymers?
Why are lipids made up of a string of oxygen, and not attaching a sequence of the same monomer molcule
What is dehydration synthesis?
What is the process of forming a covalent bond between two molecules to form a macromolcule, creating water in the process
