Lesson 3
what's the relationship between stimulus & receptor proteins?
stimulus is sensed by proteins which sends signals through the nerve
what is a nerve that sends signals from the face to the brain to sense taste?
facial nerve
if mom & dad have brown hair does that mean I'm defiantly going to have brown hair?
No, Not necessarily
what is a chemical code that contains the instructions to build proteins?
Genes
what's an allele?
different versions of the same gene
what's the connection between the function of a protein & the shape?
the shape of the protein determines how it functions
what is a physical characteristic of a person that can be passed down from a parent to a child?
Inherited trait
do they have a dominant trait? (dd)
No
what is the 20 different building blocks which make up all proteins in the body?
Amino Acids
how do we use our taste buds?
to get the signal to the brain & that let's use know what we're eating
how do proteins determine traits?
the shape of the protein or receptor protein determines the trait
what is Cells in the back of the eye that help us to see black and white?
Rods
what hair color do they have if brown is recessive and black dominant? (bB)
Black
what is a molecule made up of a chain of amino acids that performs tasks like sensing stimuli, signaling cells, causing chemical reactions, and regulating our bodies?
Proteins
how can we see?
because the light goes through your eye then through the signal to get to your brain
why do some humans see colors differently?
opsins can overlap other opsins that can cause you to see colors the same
what is a chemical reaction within a human cell that travels along a nerve cell to the brain?
Signal
if you have black hair and your mom & dad have brown does that mean your adopted?
No
what is the chemical building block that makes up genes?
DNA
what colors can Joe not see that well?
Red,Yellow,Green,and Purple
what can cause differences in how our senses work?
by different shaped protein receptors
what is Cells in the back of the eye that help us to see color?
Cones
if John's mom is having another offspring & John's eyes are Blue and mom's eyes are green, Because blue is dominant over green & the offspring has one dominant pair are they blue or green?
blue eyes
what is a Product of reproduction, a new organism produced by one or more parents
Offspring
are Joe's red and blue signals over lapping or red and green signals?
Red & green
