Assessing biodiversity:

(a) requires an approach that completely ignores personal bias and interests.
(b) is not a concern of conservation biology.
(c) is not completely objective.
(d) requires counting all of the microscopic prokaryotes in a habitat.
(e) requires counting all of the eukaryotic organisms in a habitat.

The correct answer will be option-A

Explanation:

Biodiversity refers to the diversity of the biological entities present in an ecosystem. Biodiversity has a wide spectrum which not only includes the number of the diversity of the organism but also the interaction between them.

The biodiversity is assessed to study the changes that are taking place in an ecosystem, to study the causes and how the changes affect the human well being.

The assessment decisions ignore the personal interests and the biasness as the aim of the approach is not fulfil the personal needs but to maintain sustainable management of the ecosystem.

Thus, option-A is the correct answer.

european union policies. the eu's long-term objective is to achieve levels of air quality that do not result in unacceptable impacts on, and risks to, human health and the environment. eu policies aim to reduce exposure to air pollution by reducing emissions and setting limits and target values for air quality.

the main environmental problems in western europe were: energy production/acid rain, nuclear power/waste, air pollution/climate, heavy metals, pesticides, water pollution, solid waste, and unforeseen accidents. many environmental problems are common to most european countries.
