Lactase Persistence / Lab
This large sugar is within all dairy products (milk, cheese, etc.)
What is Lactose
This is a protein that is produced in fat cells during a meal
What is Leptin
This is a hormone that helps to regulate sleep-wake cycles in animals.
What is melatonin.
The preserved remains or traces of organisms that lived in the past.
What are fossils.
The scientific study of life and living things, from tiny bacteria and plants to giant whales and humans.
What is biology.
This protein helps the body break down lactose into glucose.
What is Lactase
The production of leptin makes a person ____ hungry.
What is LESS hungry.
This is the natural, internal process that regulates an organism’s day-night or sleep-wake cycle that repeats roughly every 24 hours.
What is the Circadian Rhythm.
the concept that different species evolved from a single, shared ancestor in the distant past.
What is Common Ancestry.
This dinosaur was on the first slide of the Common Ancestry slides?
(Hint: it was also on the last page of the worksheet)
What is a Spinosaurus.
These are the building blocks of proteins
What are Amino Acids
This is the process by which cells make proteins.
What is protein synthesis.
This is the role of light in melatonin production.
Bright light inhibits (hinders/stops) melatonin production
Give an example of two modern organisms who have a common ancestor.
Tiger, Lion: Saber Tooth Tiger
Alligator, Chicken: Tyrannosaurus Rex
African Elephant, Asian Elephant: Woolly Mammoth
What is the relationship between the independent and dependent variable?
Independent Variable: Cause, manipulated
Dependent Variable: Effect, measured
When DNA is transcribed into mRNA, the DNA base pairs match up as follows:
A:__ T:__ G:__ C:__
A:U T:A G:C C:G
This is where the first step of protein synthesis takes place.
What is the nucleus.
This is a small gland in the brain where melatonin is produced.
What is the Pineal Gland.
When traits that evolved for past environments are not well-suited for current environments.
What is Evolutionary Mismatch
Spell both Ms. T and Mr. T's names correctly.
Ms. Troncoso
Mr. Trifoli
The mRNA base sequence UUA would correspond to this amino acid.
What is Leu
This is what happens if the leptin receptor becomes over-stimulated.
What is Leptin Resistance.
The leptin no longer fits inside of the receptor and does not communicate to the hypothalamus to reduce appetite.
Provide ATLEAST 2 reasons why sleep is a crucial process for humans.
. reinforces the cardiovascular and immune systems and helps regulate metabolism.
. helps reinforce learning and memory.
. energy
Explain how evolution created mismatch problems?
Evolutionary mismatch happens when traits that were helpful in past environments are no longer useful or cause problems in modern environments, because the environment has changed faster than evolution.
What does "G.R.I.T" stand for in G.R.I.T Bucks?
Growth
Responsibility
Integrity
Thoughtful Communication
