If you wanted to try and identify or classify archaea or eubacteria, you would _____
study their habitat
study their genetic make-up
study their shape and arrangement
conduct Gram staining
study how they gain energy and nutrients
study how they move
Answer: study their habitat
study their genetic make-up
conduct Gram staining
Explanation:
Study their habitat: The members of domain Archea can be identified easily as these organisms are thermophiles and halophiles which means they can be found in extreme heat and extreme saline conditions. Eubacteria are prokaryotic organisms that can be found everywhere on planet Earth.
Study their genetic make-up: Although the members of domain Archea and domain Eubacteria are prokaryotes but they can be identified as separate organisms through their genetic-make up.
Conduct Gram staining: The cell membranes of the Archea do not possess peptidoglycan thus they take up the gram negative stain. The eubacteria may take up gram positive or gram negative stain.

Active transport requires energy because unlike osmosis and diffusion which are passive transport methods which sees where the particles are moving along the concentration gradient, in active transport, the particles are moving against the concentration gradient and as such energy through ATP is needed for the particles to be transported.
The answer is restriction enzymes. These staggered ends are important in recombination of DNA since they allow DNA strands with complementary sticky ends to be easily joined into one piece by DNA ligase. Other restriction enzymes produce blunt ends. These are harder to join by DNA ligase. An example of a restriction ezyme if EcoRI
Bromothymol blue is an indicator for weak acids and bases.It is used to observe photosynthetic acvtivities and for respiratory indication.
Blue Bromothymol indicator will turn to green then to yellow when CO2 is added.When O2 is added, no effect is noticed in the Blue Bromothymol because Oxygen doesnot affect the pH.
In a summary, the color indication follows;
- Yellow-to indicate acidic
- Green-for neutral solutions
- Blue-for alkaline solutions.
