Solar System
What causes the tides on Earth?
The gravitational pull of the Moon and the Sun.
What is the primary source of energy for most ecosystems?
The Sun.
What term refers to the variety of living species in an ecosystem?
What is the molecule that carries genetic information in living organisms?
DNA
How are blood type and genetics related?
Blood type is inherited from parents based on combinations of alleles (A, B, or O) passed down.
True or False: Uranus is the second planet in the solar system.
False.
Which trophic level would only receive about 1% of the producers' energy?
Secondary consumers.
Give an example of an animal that evolved due to natural selection.
Any animal.
If one parent has type O blood and the other has type AB, what are the possible blood types of their child?
A and B.
What is the primary function of red blood cells?
Transporting oxygen using hemoglobin.
The seasons are demarcated by four special days in the year. What are the special names for each season?
Winter Solstice, Spring Equinox, Summer Solstice, Autumn Equinox.
Explain the role of decomposers in an ecosystem.
Breaking down dead organisms and recycling nutrients into the soil.
What evidence do fossils provide for evolution?
Fossils show changes in species over time and transitional forms.
What do we call a segment of DNA that codes for a specific protein?
What would happen if a person receives incompatible blood in a transfusion?
Their immune system would attack the donor blood, causing a potentially fatal reaction.
Why do we always see the same side of the Moon from Earth?
Because the Moon’s rotation and revolution periods are the same (synchronous rotation).
Which nutrient cycle includes condensation?
The water cycle.
Explain how mutations contribute to evolution.
Mutations create genetic variation, which can lead to new traits that may provide survival advantages.
What is the term for organisms that have two identical alleles for a trait?
Homozygous.
Which blood component is responsible for clotting?
Platelets.
Constellations serve these four functions.
As a map to navigate, as a book of stories, as a calendar, and as a specific region in the sky.
How does phosphorus typically enter ecosystems?
Through weathering of rocks and minerals.
How does the theory of common descent support the idea of evolution?
All species share a common ancestor, and evidence includes shared DNA and similar anatomical structures.
Explain the relationship between chromosomes, genes, and DNA
Chromosomes are made of DNA, and genes are segments of DNA that code for traits.
Determine the blood type of this sample.
Anti-A: no clumping. Anti-B: Clumping. Rh: No clumping.
B-
