Forces
An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.
What is Newton's first law of motion?
Crust, mantle, outer core, and inner core.
What are the layers of the Earth?
the basic unit of structure and function in all living things
What is a cell?
The combining of DNA and traits from two parents creating offspring with genetic variation.
What is sexual reproduction?
change over time
What is evolution?
A property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
What is inertia?
Heat and Pressure
Which steps are needed to form metamorphic rock?
Cell wall, chloroplasts, and a central vacuole.
Which organelles do plants have that animals don't?
a change or the process of change by which an organism or species becomes better suited to its environment, such as nest building, herding, schooling and flocking, bird song, and color patterns.
What is adaptation?
fossils found in lots of locations from the same time in history
What are index fossils?
By using a larger battery and wrapping more coils of wire around the nail.
How do you make an electromagnet stronger?
Weathering, erosion, deposition, compaction, and cementation
What are the steps required to form sedimentary rock?
Cells throughout an organism develop in different ways to perform different tasks.
What is cell specialization? OR What is cell differentiation?
Creates slightly different versions of the same genes, called alleles. These small differences in DNA sequence make every individual unique. They account for the variation we see in individual organisms.
What is mutation?
when very different animals have bones that appear very similar in form or function and seem to be related.
What are homologous structures?
The quantity of matter that an object is composed of.
What is mass?
When tectonic plates move away from each other.
What is a divergent plate boundary?
They circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
How do the circulatory and respiratory systems interact?
A rancher chooses to breed only the chickens that lay big eggs. Eventually the only chickens the rancher has are chickens that lay big eggs.
What is artificial selection? OR What is animal husbandry?
An organism's ability to survive and reproduce in a particular environment. Such as, if sharp teeth increase organisms ability to survive and reproduce, then genes causing teeth to be sharp will increase in frequency.
What is fitness?
Every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. (i.e. more mass=more force and greater distance = less force)
What is Newton's law of universal gravitation?
When one tectonic plate gets pushed back down into the mantle.
What is subduction?
Leaf, stem, root, and flowers.
What organs do plants have?
A scientist inserts a gene into a corn plants DNA that makes it so that the plant doesn't die when sprayed with poison. This lets farmers spray their fields with poison to kill the weeds without harming the corn plants.
What is genetic modification? OR What is a genetically modified organism (GMO)?
an anatomical feature or behavior that no longer seems to have a purpose in the current form of an organism of the given species.
What are vestigial structures (vestigial organs)?
