Widespread, intense coral bleaching and mortality occurred across the Ryukyu Islands, southern Japan, in the summer and autumn of 1998. All of the corals within the study area, dominated by arborescent Acropora, at Iriomote Island (Ryukyu Islands), had been bleached by October 1998, and were completely dead and covered by filamentous algae in October 1999. The adult fish assemblage in the area was monitored before (1995-1997), during (1998), and after (1999) the bleaching event, the monitored area during those intervals being termed ‘living’, ‘bleaching’, and ‘dead’ coral areas, respectively. The numbers of fish species and individuals were significantly greater in the living and bleaching coral areas than in the dead coral area, there being no differences in these variables between the former two areas. The reduction in numbers in the dead coral area was due to the complete disappearance of obligate corallivores. These results suggest that fishes other than corallivores have no particular response to coral bleaching and subsequent mortality as long as the high structural complexity of bleached corals is preserved.

How does the body of a 100m sprinter produce energy for this event?
mafiozo [28]
Its estimated that during sprint events approximately 95% of energy production comes via the anaerobic system (85% phosphate, 10% anaerobic glycolysis), and only 5% from aerobic oxygen. Thus, the 100m sprint is an anaerobic event relying heavily on energy supply from the ATP-PC system!

Vlad [161]

Answer:

  1. <u>The hours are the independent variable.</u>
  2. <u>The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .</u>
  3. <u>The domain is 0 to 30 </u>
  4. <u>The range is 0 to 330 </u>

Explanation:

<em>The hours are the independent variable and  should be plotted on the x-axis .</em>

<em>The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked )  and should be plotted on the y-axis </em>

<em>--------------- </em>

<em>Let +W+ = wages/wk earned </em>

<em></em>

<em>Let +h+ = hours/wk worked </em>

<em>The equation is: </em>

<em>+W+=+11h+ </em>

<em>The domain is 0 to 30 </em>

<em>( no hrs worked to 30 hrs worked ) </em>

<em>The range is 0 to 330 </em>

<em>( no wages eared to +11%2A30+=+330+ earned )</em>

ki77a [65]

<u>Answer</u>:

"Genetic Diversity" best explains why Caitlin has blue eyes and Jack has green eyes.

<u>Explanation</u>:

It can be known as the total genetic characteristic in the genetic make up of species. It can also be differentiated from the genetic variability, which explains the tendency of variation of genetic characteristic. It also serves as the way for various populations to adapt to environmental variation. It is an important phenomenon which further helps in maintaining the health of the population which includes the alleles which are important for resisting diseases.
