Answer 3

The extremophile that produces enzymes used in the production of detergents is alkaliphiles.

Answer 4

Which organism provides evidence that matter and energy can be cycled through an ecosystem without sunlight?(1 point)
Responses

a bison in a North American prairie
a bison in a North American prairie

a tree in a South American rain forest
a tree in a South American rain forest

a lion in an African savanna
a lion in an African savanna

a lanternfish on the Atlantic Ocean floor

Answer 5

The organism that provides evidence that matter and energy can be cycled through an ecosystem without sunlight is a lanternfish on the Atlantic Ocean floor. This example demonstrates that ecosystems, such as those found in deep-sea environments, can thrive using chemosynthesis or other energy sources independent of sunlight.

Answer 6

Suppose you are an exterminator of organisms that undergo chemosynthesis. Which technique will prove most effective to eliminate the greatest number of organisms?(1 point)
Responses

remove methane and hydrogen sulfide
remove methane and hydrogen sulfide

block sunlight
block sunlight

decrease the temperature
decrease the temperature

remove oxygen and carbon dioxide

Answer 7

The technique that will prove most effective to eliminate the greatest number of organisms that undergo chemosynthesis is to remove methane and hydrogen sulfide. These compounds are key energy sources for many chemosynthetic organisms, and their removal would disrupt their ability to produce energy and survive.

Answer 8

With liquid water underneath its icy surface, Jupiter’s moon Europa is often cited as a potential site for extraterrestrial life. What other compounds would indicate that chemosynthesis supports life on the planet?(1 point)
Responses

methane
methane

hydrogen peroxide
hydrogen peroxide

glucose
glucose

oxygen

Answer 9

The compound that would indicate that chemosynthesis supports life on the planet is methane. Methane can be a byproduct of microbial activity and is often associated with environments where chemosynthesis might occur, particularly in the presence of other compounds like hydrogen sulfide.
