Exam 7: Searching for Life in Our Solar System

Which kind of robotic space mission enables us to determine the chemical composition of a planet's surface and atmosphere remotely?

Venus may have been more Earth-like in the past because

Based on its distance from the Sun, we would expect the surface of Venus to be

Europa may have a subsurface ocean of liquid water due to

Which kind of robotic space mission enables us to determine the chemical composition of a solar system body in a laboratory?

Habitability generally refers to an environment capable of sustaining

Photosynthetic life existing on a planet much farther from the Sun than the Earth would most likely

The necessary elements of life should

What happens to the rate of most chemical reactions as the temperature decreases?

In searching for life in the solar system, which basic requirement of life is the most fundamental and the one we always look for?

Small bodies like asteroids and comets are unlikely to harbor life because they

Which of the following planets has not yet been studied with an orbiter

If life exists on Mars today, it will most likely be found

The search for life in the solar system is essentially a search for

The biggest obstacle to life being present in the atmospheres of Jupiter and Saturn is the

If we place living cells in a nonpolar solvent like methane or ethane,

Molecules like water in which electrons are distributed unevenly within the molecule are referred to as

The strong forces of attraction that exist between water molecules and are responsible for many of its unique properties as a solvent are called

Most of the carbon dioxide on the Earth

Since chemically based life requires biological molecules to come into contact with each other, this will require a planet with
