Newton’s First Law of Motion states that objects in motion remain in motion unless acted upon by an outside force, and objects at rest stay at rest unless acted upon by an outside force. This statement is also referred to as the law of
Which atmospheric layer contains the ozone layer?
Humans can breed plants and animals to have useful traits. By selecting which animals are allowed to reproduce, humans can influence an organism’s genotype. What name did Darwin use to describe this process?
Survival of the fittest
Artificial selection, on the other hand, is the reproduction of organisms with beneficial traits resulting from the influence of humans.
Which of the following is equal to the atomic number of a chemical element?
Number of protons
Number of neutrons
Number of atoms
Which type of symbiotic relationship takes place when one member of the association benefits while the other is harmed?
Parasitism is a symbiotic relationship in which one organism benefits while the other is harmed. For example, tapeworms are parasitic to humans because they consume nutrients from the human host, depriving the host of these nutrients.
Mutualism is a symbiotic relationship in which both organisms benefit from the relationship.
Commensalism is a symbiotic relationship in which one organism benefits while the other is neither harmed nor helped.
In the field of genetics, an organism’s appearance is referred to as its:
The tilt of the Earth's rotational axis toward or away from the sun causes:
Daylight savings time
The Big Bang theory is a model used to explain the:
Reason the universe was created
Beginning of life
Origin of the universe
Law of gravity
Animals that feed exclusively on plants are called:
Which of the following biological classifications is the largest and most inclusive?
The energy of an object resulting solely from motion is:
Sara jumped off her row boat into the lake. As she pushed her body forward the boat moved backwards. Which of Newton’s laws best describes the motion of Sara and her boat?
Newton’s Law of Universal Gravitation
Newton’s First Law of Motion
Newton’s Second Law of Motion
Newton’s Third Law of Motion
Newton’s First Law of Motion states that objects in motion remain in motion unless acted upon by an outside force; objects at rest stay at rest unless acted upon by an outside force. For example, if a ball is sitting on the floor, it will stay on the floor until someone kicks it.
Newton’s Second Law of Motion states that the acceleration of an object is equal to the net force acting on it divided by an object’s mass. For example, when you throw a ball, the harder you throw, the more the ball accelerates.
Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction. The same force that Sara used to push forward made the boat move backwards.
A sudden intense brightening from a small area of the Sun's surface is called a:
Sunspots are temporary dark spots that sometimes appear on the surface of the Sun. Prominences are huge loops of gas that erupt from sunspot regions. Quasars are the very bright centers of distant galaxies.
Waves bend when they move around obstructions or pass through narrow openings. This type of bending is called:
Diffraction is the bending of waves as they pass through an opening or around a barrier in their path. We can hear around a corner because of the diffraction of sound waves.
Reflection is the change in direction of waves when they bounce off a barrier. Refraction is the change in direction of waves as they pass from one medium to another.
What is true of Meiosis?
It involves only one cell division
It is used to generate sex cells
It results in the formation of two diploid daughter cells
It produces genetically identical cells
Two objects on Earth are dropped from the top of a building that is 70 meters high. Object A has a mass of 12 g and object B has a mass of 6 kg. Assuming there is no air resistance, which object will hit the ground first?
Both objects will hit the ground at the same time
