Question 1
What is solar energy?
-
AWindmills
-
BElectric cars
-
CRechargeable batteries
-
DEnergy from the sun
Energy from the sun
Solar energy is radiation from the sun capable of producing heat, causing chemical reactions, or generating electricity.
Question 2
A ____ is a tiny, one-cell thick blood vessel that carries blood between an artery and a vein.
-
AArtery
-
BPulmonary vein
-
CVena cava
-
DCapillary
Capillary
In the lungs, blood travels through many small, thin blood vessels called capillaries. It picks up more oxygen and transfers carbon dioxide to the lungs.
Question 3
Photosynthesis occurs in the chloroplasts of _____.
-
ARocks
-
BPlants
-
CDogs
-
DAnts
Plants
Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Question 4
What is the anatomical word for wrist?
-
ACrural
-
BCoxal
-
CCarpal
-
DOrbital
Carpal
Bones of the hand include the carpal bones (wrist bones), metacarpal bones (bones of the hand proper), and phalanges (finger bones).
Question 5
The structure of DNA is called a ____.
-
ADiamond
-
BLipid membrane
-
CSemi-circle
-
DDouble helix
Double helix
Deoxyribose sugar molecules and phosphate molecules form the outer edges of the DNA double helix, which resembles a spiral ladder, and base pairs bind the two strands to one another.
Question 6
Which system is responsible for the secretion of hormones?
-
ACardiovascular
-
BRespiratory
-
CEndocrine
-
DDigestive
Endocrine
The endocrine system includes eight major glands throughout the body. These glands make hormones, which are chemical messengers that travel through the bloodstream to tissues or organs and affect processes from growth and development to sexual function and mood.
Question 7
What is the main purpose of a microscope's illuminator?
-
AProvides a steady source of light
-
BMagnifies the sample
-
CHolds the eyepiece
-
DProvides stability
Provides a steady source of light
The most common microscope (and the first to be invented) is the optical microscope, which uses light to pass through a sample to produce an image.
Question 8
A renewable resource is a resource that _______.
-
AComes in a limited amount
-
BIs naturally reoccurring
-
CCan be easily made
-
DIs never used
Is naturally reoccurring
A renewable resource is a natural resource that cannot be used up or it is one that can be replaced within a human lifespan.
Question 9
What system plays a vital role in the existence of the human species?
-
ARespiratory
-
BCardiovascular
-
CAll of the above
-
DReproductive
All of the above
The human reproductive system is an organ system by which humans reproduce and bear live offspring.
Question 10
What is a light-year?
-
AThe distance that light travels in one year
-
BA shorter than average year
-
CThe time it takes light to travel from the sun to Earth
-
DA figurine in Toy Story
The distance that light travels in one year
A light-year in astronomy is the distance traveled by light moving in a vacuum in the course of one year. Astronomers use the light-year as a unit of length to measure the vast distances in space.
Question 11
Where is genetic material contained in the cell?
-
AWithin the nucleus
-
BWithin the ribosomes
-
CWithin the nucleolus
-
DWithin the cytoplasm
Within the nucleus
The nucleus of a eukaryotic cell contains the DNA, the genetic material of the cell. The DNA contains the information necessary for constructing the cell and directing the multitude of synthesis tasks performed by the cell in the process of life and reproduction.
Question 12
The first law of thermodynamics states:
-
AComponents of a system interact
-
BEnergy is conserved; it can be neither created nor destroyed
-
CThe entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero
-
DIn an isolated system, natural processes are spontaneous when they lead to an increase in disorder, or entropy
Energy is conserved; it can be neither created nor destroyed
The first law of thermodynamics describes how energy is conserved. It says that the change in the internal energy of a system is equal to the sum of the heat gained or lost by the system and the work done by or on the system.
Question 13
What connects muscle to bones?
-
ALigaments
-
BCartilage
-
CTendons
-
DJoints
Tendons
Tendons are the connective tissues that transmit the mechanical force of muscle contraction to the bones. The tendon is firmly connected to muscle fibers at one end and to components of the bone at its other end. Their great strength, which is necessary for withstanding the stresses generated by muscular contraction, is attributed to the hierarchical structure, parallel orientation, and tissue composition of tendon fibers.
Question 14
Which star is the hottest?
-
AOrange
-
BYellow
-
CBlue
-
DRed
Blue
Stars can range in temperature, from the relatively cool red dwarfs to superhot blue stars. The hotter the star, the further up the spectrum you go.
Question 15
Plate ____ are where most earthquakes occur.
-
ACenters
-
BInteriors
-
CMantles
-
DBoundaries
Boundaries
Most earthquakes occur along the edge of the oceanic and continental plates where two plates are running into or sliding past each other. Earthquakes can also occur far from the edges of plates, along faults. Faults are cracks in the earth where sections of a plate (or two plates) are moving in different directions.
Question 16
What is Earth's core made of?
-
ANickel and iron
-
BCarbon and iron
-
CHelium and hydrogen
-
DCarbon and helium
Nickel and iron
At the center of the Earth lies the core, which is nearly twice as dense as the mantle because its composition is metallic (iron-nickel alloy) rather than stony. Unlike the yolk of an egg, however, the Earth's core is actually made up of two distinct parts: a 2,200 km-thick liquid outer core and a 1,250 km-thick solid inner core. As the Earth rotates, the liquid outer core spins, creating the Earth's magnetic field.
Question 17
What system has the largest organ in the body?
-
ADigestive
-
BIntegumentary
-
CReproductive
-
DCardiovascular
Integumentary
The integument is a network of features in biology that forms the covering of an organism. Examples include the hard shield of an armadillo and the furry coat of an Arctic bear.
Question 18
What kind of wave is a sound wave?
-
AElectromagnetic
-
BLongitudinal
-
CRadiant
-
DTransverse
Longitudinal
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it spreads away from the source of the sound. The source is some object that causes a vibration such as a ringing telephone, or a person's vocal chords disturbs the particles in the surrounding medium.
Question 19
How do enzymes speed up reactions?
-
AThey raise activation energy
-
BThey lower activation energy
-
CThey supply extra reactants
-
DThey change the temperature
They lower activation energy
Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative pathway of lower activation energy.
Question 20
What is the smallest particle of soil?
-
ASilt
-
BClay
-
CLoam
-
DSand
Clay
Three categories for soil particles have been established - sand, silt and clay. These three groups are called soil separates. The three groups are divided by their particle size. Clay particles are the smallest, while sand particles are the largest.

@MilitaryindustrialAesthete no one gives a sh*t lol, gl in hiseschool
I’m a 5th grader and I got 9/20
O well. Guess I'm not much smarter than anything at all. Too bad everything before this has already let me know that. Thank you very much.
