Answer: alternative C
Explanation: Aerobic bacteria are oxygen dependant, and because of that they gather in blue and red areas since those are the <u>light spectra in which algae photosynthethises</u> the most. The <u>photosynthesis product is oxygen</u>, being this the reason why blue and red areas attract aerobic bacteria.
Answer:
The skinfold method, the measurement of subcutaneous fat folds, is the most widely adopted field method for the assessment of body fat, especially in children.
It is based on the principle that fat is of a known density and by “summing” measurements of subcutaneous fat thickness across the body, total and regional fat can be estimated.
Skinfold thickness measurements are typically used to rank individuals in terms of relative total “fatness”, or to assess subcutaneous fat at various regions of the body.
Population specific equations are used to derive estimates of percent body fat.
In infancy, it might be the sole tool available for assessing body composition longitudinally as other methods may not be feasible, or may only be suitable for use at body sizes e.g. PEA POD, can only measure infants up to 10kg.
Biotite mica and muscovite mica have different chemical compositions. Compared to the magma from which biotite mica forms, the magma from which muscovite<span>mica forms is usually more felsic and less dense. </span>
It has meanwhile been shown that the most sensitive cells are those that areundifferentiated, well nourished, dividing quickly and highly active metabolically. Amongst the body cells, the most sensitive are spermatogoniaand erythroblasts, epidermal stem cells, gastrointestinal stem cells.

Answer: The correct option is A
Archae bacteria are extremophiles which thrive in extremely environment.
Explanation:
Extremophiles are organisms that inhabit extreme environments. They thrive in hot niches, ice, and salt solutions. Some of them grow in toxic waste, organic solvents and heavy metals. Extremophiles include members of all domains of life which are bacteria, archea,and eukaryotes. Out of these three members of extremophiles, archea are the main group of microorganisms to thrive in extreme environments. This is because the archea are skilled in adapting to different extreme conditions than bacteria and eukaryotes.
Archea are hyper thermophilic microorganisms.
