Question

graph 1 title
% hatched
salinity ( % )
what can you correctly say based on the graph above? check all correct options:
as the salinity increases from.65% to 2.5%, the % of eggs that hatch increases.
overall, % eggs hatching increases with increasing % salinity.
the highest % of eggs hatch at 2.5% salinity.
as the salinity increases from 2.5% to 5%, the % of eggs that hatch increases.
as the salinity increases from 2.5% to 5%, the % of eggs that hatch decreases.
the highest % of eggs hatch at 5% salinity.

Explanation:

1. For salinity 0.65% (≈40% hatched) to 2.5% (60% hatched), the hatching percentage rises.
2. Overall, hatching % rises then falls with salinity, so the overall increase claim is false.
3. The highest hatching value (60%) is at 2.5% salinity.
4. From 2.5% (60%) to 5% (≈7% hatched), hatching percentage drops, so the increase claim is false.
5. From 2.5% to 5%, the hatching percentage clearly decreases.
6. The lowest hatching value is at 5% salinity, so this claim is false.

Answer:

• As the salinity increases from.65% to 2.5%, the % of eggs that hatch increases.
• The highest % of eggs hatch at 2.5% salinity.
• As the salinity increases from 2.5% to 5%, the % of eggs that hatch decreases.
