AEST Exam Questions and Answers Fully Solved Latest Version 2025-2026
Opportunities applicable for the use of using biotechnology to promote animal health. -
AnswersAnimal welfare can increase livestock productivity, and the impact on the environment.
With the bio-tech advancements of ability to detect, treat and prevent diseases.
What equipment is used to maintain the aseptic technique for a tissue culture facility? -
AnswersMaintaining PPE, transfer hood, filtered tips, and sterilized media.
What are the negative and positive effects of agricultural practices on the environment? -
AnswersThe environment can positively be affected by giving a positive effect to the organisms
that follow; birds and predatory insect; and earthworms and flora. Negatively affecting the
environment by increasing the amount of trapped green house gasses, decreasing the amount
of biodiversity, and the accumulation of pesticides.
Methods for bio-treatment of biological and chemical wastes? - AnswersWhen discarding
biological waste bacterium and other microorganisms are used to break down the organic
material. When disposing of chemicals, they must be disposed of through the EHS Hazardous
waste program.
What are the negative aspects of the technologies used to create bio-fuels from biomass? -
AnswersA negative aspect to the use of biomass pertains to the amount of space that is
needed for the technological conversion of organic material to an energy source.
What are the positive aspects of the technologies used to create bio-fuels from biomass? -
AnswersA positive aspect would be due to how biomass in its self is widely available as a
renewable resource of energy, which is carbon friendly and reduces the over-reliance of fossil
fuels.
How are bio-fuels created with biomass? - AnswersWhen biomass is heated in the absence of
air, the organic material releases an energy that was gained prior, from the sun. Which can then
be burnt like a fuel or refined into chemicals used as fuel.
Risks applicable for the use of using biotechnology to promote animal health. - AnswersRisks
on animal health are horizontal gene transfer, the disruption of ecosystems, and native species
extinctions.
Benefits applicable for the use of using biotechnology to promote animal health. -
AnswersGenetic technology can be used for cloning which can increase the growth rate and
improve the quality of the animal in the sense of; leaner meat, disease resistant, and increased
muscle mass.
Biomass - AnswersTotal amount of living tissue within a given trophic level.
