U1D6 : Kingdom Archaebacteria & Kingdom Eubacteria

Flashcards covering key concepts from the lecture on Kingdom Archaebacteria & Eubacteria, including taxonomy, cell types, diseases like Tuberculosis, extremophiles, deep-sea mining impact, and microscope usage.

What are the three main domains of life?

Archaea, Bacteria, and Eukarya.

Which two kingdoms are classified as prokaryotic?

Kingdom Archaeabacteria and Kingdom Eubacteria.

Which kingdoms are classified as eukaryotic?

Kingdom Protista, Kingdom Fungi, Kingdom Plantae, and Kingdom Animalia.

According to the six-kingdom classification system, what are the names of these kingdoms?

Archaeabacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.

Which specific bacterium is responsible for causing Tuberculosis (TB)?

Mycobacterium tuberculosis.

What was the second leading infectious killer worldwide in 2023, after COVID-19?

Tuberculosis (TB).

What group of organisms, belonging to the Domain Archaea, are known for living in extreme environments?

Extremophiles.

Name two types of extreme environments where extremophiles (Archaeabacteria) can be found.

Hydrothermal vents, terrestrial hot springs, highly saline environments, acidic environments, or anaerobic environments.

What human activity is currently threatening the biodiversity in Kingdom Archaeabacteria, particularly in deep-sea locations?

Deep sea mining.

Which international body, under the UN, is tasked with governing the mineral resources of the ocean floor in international waters?

The International Seabed Authority (ISA).

When first focusing a specimen under a microscope, what is the initial adjustment one should make?

Adjust the diaphragm.

Which adjustment knob should be used when focusing with the low power objective lens on a microscope?

The coarse adjustment.

When switching from a lower power to a higher power objective lens on a microscope, which adjustment knob should be used to refine the focus?

The fine adjustment.

Name three key parts of a microscope.

Base, diaphragm, stage, clips, objective lenses, nosepiece, body tube, arm, or eyepiece/ocular lens.

How is the total magnification of a microscope calculated for the observed specimen?

By multiplying the eyepiece/ocular lens magnification by the objective lens magnification.
