Answer is A.
Archaea requires neither sunlight for photosynthesis as do plants, nor oxygen. Archaea absorbs CO2, N2, or H2S and gives off methane gas as a waste product the same way humans breathe in oxygen and breathe out carbon dioxide. An example is chemosynthetic bacteria by sea drifts. They use chemical energy to produce vital processes to live.
The answer to number 2 would be as the number of carbon carbon 2ble 2ble bonds increase, the melting point decreases
Answer: D
Explanation: i've taken bio
Answer:
Explanation:
Alkali metals (rarely 'Hydrogen and the alkali metals')
Alkaline earth metals (in old chemistry this name applied only to Ca and its congeners)
Icosagens (unofficial name; aka Boron group; rarely Earth metals)
Crystallogens (unofficial name; aka Carbon group; rarely Adamantogens[a] or Merylides[b])
Pnictogens
Chalcogens
Halogens
Noble gases (rarely Aerogens). The Group name may have to be changed to the “Helium group” since oganesson is not expected to be noble.
D. Evaluate
Explanation:
The team of ecologists failed to implement the evaluation stage of adaptive management approach as the didn't compare various possible methods that could be used for the managemenr process and evaluation refers to analysis of completed or ongoing activities related to the topic in consideration to determine the management effectiveness and efficiency. Since they forgot to evaluate the various possible methods, evaluation is the missed approach.
