Bonds
What bond joins atoms into molecules through electron sharing
covalent bond
What is the number on the top right of an element called?
Atomic number
polymers called polysaccharides made from monomers called monosaccharides
What is the structure of lipids
Lipids are grouped together with no full or partial charges (nonpolar) and are hydrophobic
What does the electronegativity of an atom mean
Hoe much an atom wants or pulls electrons
What bond transfers an electron to the other atom
Ionic Bond
What is the atomic weight of an element
the mass of protons + mass of neutrons
What are sugars
sugars like glucose are used by cells in all organisms to do cellular work, made by plants using photosynthesis
What fat has the maximum number of hydrogen bonded to their carbon chain
Saturated fats
What is artificial selection
Selecting the best one and breeding it
What type of bond is the equal sharing of electrons between atoms
Nonpolar covalent bond
What is the charge of a proton
Proton is positively charged
How are starches used
Starches are used by plants to store energy by liking together sugar monomers (glucose) into long chains
What fat has a double bond between carbon atoms
Unsaturated fats
What is natural selection
mechanism for evolution. (individuals with more favorable traits are selected, the next generation inherits those traits)
What type of bond is the unequal sharing of electrons between atoms
Polar covalent bond
What is the charge of a neutron
What is glycogen and what is it used for
a type of starch used by animals to store glucose in liver and muscle tissue
What fat has hydrogens on the opposite side of the carbon bonds
Trans fat
What is convergent evolution
When organisms who live in similar conditions evolve similar structures separartely
What bond is a weak bond characterized by a partially positive hydrogen on one molecule and a partially negative atom such as fluorine, oxygen, or nitrogen on another molecule
hydrogen bond
What is the charge of an electron
Electron is negatively charged
What is cellulose
is used by plants as structural support. Long chains of glucose are help together by glycosidic linkages.
Which fat is the worst to consume and why
Trans fat is the worst fat to consume because its structure chain can stack up and block blood flow
What is homologous structures
Features that often have different functions across species but are structurally similar
