Traits & Reproduction
What is the difference between a feature and a trait?
Feature: all species members have it
Trait: specific to an individual
Energy always transfers from _____ to _______
hot to cold
Why do ocean currents near the equator carry more energy?
They receive more direct sunlight - more energy from the sun
Team A adds 1 cup of ice.
Team B adds 2 cups of ice.
Which water will be colder after 3 minutes?
Team B
Ocean currents near the equator are __________ and ocean currents near the poles are ___________.
Ocean currents near the equator are warmer and ocean currents near the poles are colder.
In a certain species of plant, the color red (R) is dominant to the color white (r). According to the Punnett Square, what is the probability of an offspring being red?
Plant 1: Rr
Plant 2: rr
50%
What happens to particle movement when heat is added?
They move faster
Which location receives more energy from the Sun: Florida or Alaska?
Florida
Which of the following options is a Mutation if the parents' genes are: S1S2 and S2S2
a. S2S2
b. S1S2
c. S2S3
c. S2S3
Traits are passed from __________________ to __________________ through __________________.
Traits are passed from parent to offspring through sexual reproduction.
What is a mutation?
A change in genes that may be beneficial, harmful, or neutral.
What will absorb heat faster?
a. metal
b. plastic
c. wood
a. metal
What is latitude?
How far north or south a location is from the equator
Which one of these would show the recessive trait for a feature?
Tt
TT
tt
tt
Genes are the _____________ for proteins and proteins determine an organism’s _____________
Genes are the instructions for proteins and proteins determine an organism’s traits
What is the difference between a dominant trait and a recessive trait
When an offspring inherits two different genes, the trait that shows up is called a dominant trait. The trait that doesn't show up is called a recessive trait.
Which material will trap the most heat?
a. bubble wrap
b. cotton fabric
c. duct tape
d. foam cup
d. foam cup
How is energy from the Sun transferred to the air?
Energy is transferred from the sun to the Earth’s surface first, and then to the air.
What happens when a cold spoon is placed into a bowl of hot soup?
The spoons particles will move faster because it is gaining energy from the soup
Climate is influenced by the __________________ and Earth’s __________________.
Climate is influenced by the Sun and Earth’s Rotation.
What are ALL the possible gene combinations for offspring if the parents' gene combinations are:
F1F2
F2F3
F1F2
F1F3
F2F2
F2F3
Why does warm air rise and cold air sink?
Warm air has more energy, so its molecules spread out, making it lighter and causing it to rise. Cold air has less energy, so its molecules stay close together, making it heavier and causing it to sink.
How do ocean currents affect climate?
They transport warm water from the equator and cold water from the poles to the locations it passes. If the water is warmer than the air, the air receives energy from the water and gets warmer. If the water is colder than the air, the water gains energy from the air and the air gets colder.
What is the Coriolis Effect?
The Coriolis Effect occurs when Earth's rotation causes wind and ocean currents to curve instead of moving in a straight line.
Family members can have different traits because they inherit different combinations of ________________________ from their parents.
Family members can have different traits because they inherit different combinations of genes from their parents.
