The Article says:Together, they carry out research that might help future Mars missions. For example, one crew collected soil to study how to grow crops on Mars.Which means almost the same as collected?A.borrowedB.arrangedC.gatheredD.offeredSUBMITExtras

The Article says:Many of these volunteers are scientists and engineers. Others are college students. Together, they carry out research that might help future Mars missions. For example, one crew collected soil to study how to grow crops on Mars.The author uses this passage mostly to __________.A.question the usefulness of the work carried out at the MDRSB.point out that most of the scientists like the work they do at the MDRSC.show how difficult the MDRS research can be for the volunteersD.give the reason why crew members stay and do work at the MDRS

The reader can tell from the Article that __________.A.the people who work at the MDRS must be either scientists or engineersB.NASA chose some MDRS volunteers to take part in a real trip to MarsC.astronauts living on Mars might use the Martian soil to grow crops inD.the two rovers at the MDRS are just models and do not really workSUBMITExtras© 2024 Achieve3000 Inc. and its licensors.All Rights Reserved.

Which of the following is the most important rationale for the scientific study of Mars?Againing access to rare or exotic resourcesBinvestigating the existence of intelligent lifeCestablishing a colony for humansDunderstanding the evolution of the solar system

Soil may be compared to an open system as it exchanges both matter and energy with the surroundings. Choose the sequence which lists soil storages.Water, air, organic matter, organisms, nutrients and mineralsAir, water, nutrients and minerals, horizons, leaf litterPrecipitation, water, nutrients and minerals, parent material, plantsOrganisms, weathering, leaching, decomposition, water

While researching a topic, a student has taken the following notes:Researcher Emmanuel Mendoza has tried to make a pea plant bloom in soil meant to mimic Mars’s inhospitable regolith. Mendoza added a fertilizer called 'frass' to the inhospitable soil.Frass is the waste left behind by black soldier fly larvae.Gardening in space would require insects and microorganisms to keep ecological systems in working order.If astronomers are to live on a different planet for an extended period of time, they need to be able to grow their own food.The student wants to emphasize why astronomers need to bring bugs to Mars. Which choice most effectively uses relevant information from the notes to accomplish this goal?In order to sustain life in space, astronomers need to bring bugs to Mars to help maintain a working ecological system.eliminateTo garden in space, astronauts need frass, a fertilizer developed from the waste of fly larvae.eliminateScientists are investigating ways that inhospitable soil for growing, like Mars' regolith, can be made to sustain life.eliminateThe waste of black soldier fly larvae can be used to make frass, a fertilizer that can make inhospitable soil better for growing.
