DOE Middle School Science Bowl Set 4 Round 1

What process do autotrophs use to make their own food from sunlight?

What gas essential to human life do plants give off when they photosynthesize?

What is the name of the preserved remains, traces, or evidence of organisms that were formerly alive, often found in rocks?

Rounding your answer to the nearest whole number, what is 732.15 + 641.43?

Round 63,159.456 to the hundreds' place.

What is the additive inverse of 3?

What is the sum of the multiplicative inverse of 2 and the multiplicative inverse of 5 as a fraction in simplest form?

Which noble gas is most commonly used to make brightly-colored signs?

What type of charge results when you scrape electrons from your hair while brushing?

In a symbiotic relationship, what is the minimum number of organisms that benefits from the relationship?

The three components required for an oil reservoir to form are a source rock, a porous and permeable reservoir rock, and:

Deposition of primarily which compound leads to the formation of stalactites and stalagmites in caves?

Life Science

Autotrophs use photosynthesis to produce food from sunlight.
Plants release oxygen as a byproduct of photosynthesis.

Physical Science

Burning lamp oil is classified as a chemical reaction.
An engine that is 100% efficient contradicts the laws of thermodynamics.

Earth and Space Science

Fossils are preserved remains or traces of formerly alive organisms, commonly found in sedimentary rock.
Fossils are primarily located in sedimentary rock types.

Mathematics

Rounding 732.15 + 641.43 results in 1374.
63,159.456 rounded to the hundreds place is 63,200.
The additive inverse of 3 is -3.
The sum of the multiplicative inverses of 2 and 5 is 7/10.

General Science

The noble gas most commonly used for brightly-colored advertising signs is neon.
Bromine is NOT a noble gas among the options provided.
Scraping electrons from hair while brushing gives the hair a positive charge.
Hydrogen fuel cells can produce energy without using a turbine.

Symbiotic Relationships

In a symbiotic relationship, it's possible for zero organisms to benefit.

Toxins in Food Chains

Producers in a food chain will show the least accumulation of toxins compared to herbivores or predators.

Oil Reservoir Formation

An oil reservoir requires three components: source rock, porous and permeable reservoir rock, and a cap rock.

Cave Formation

Calcium carbonate deposition contributes to the formation of stalactites and stalagmites in caves.

Weathering

Chemical weathering is caused by acid rain.
Increased burning of fossil fuels can lead to a rise in acid rain.

Energy Production

Ethanol is produced by fermenting crops like corn and sugar cane, reducing dependence on fossil fuels.
Biodiesel is derived from food products, including vegetable oils and animal fats.
