1

Elements that belong to the same period in the Periodic Table of the Elements have the same number of:

50% Answer Correctly

protons

electrons

electron shells

atomic mass units
Solution

The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number. 

2

Which of the following members of the food chain are most alike?

65% Answer Correctly

primary consumers and omnivores

scavengers and decomposers

herbivores and autotrophs

producers and tertiary consumers
Solution

Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.

3

During the water cycle, water enters the atmosphere as a gas through which process?

26% Answer Correctly

both evaporation and transpiration

evaporation

precipitation

transpiration
Solution

The water (hydrologic) cycle describes the movement of water from Earth through the atmosphere and back to Earth. The cycle starts when water evaporates into a gas from bodies of water like rivers, lakes and oceans or transpirates from the leaves of plants.

4

Poor balance could indicate an issue with which part of the nervous system?

64% Answer Correctly

cerebellum

medulla

spinal cord

cerebrum
Solution

The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.

5

In the heart, blood flows from the right __________ to the lungs then back to the heart via the left __________.

55% Answer Correctly

ventricle, ventricle

atrium, ventricle

ventricle, atrium

atrium, atrium
Solution

The two largest veins in the body, the venae cavae, pass blood to the right ventricle which pumps the blood to the lungs through the pulmonary artery. Blood picks up oxygen in the lungs and returns it to the left atrium via the pulmonary vein.
