pyrrophyta

Fourth option is correct.

Step-by-step explanation:

Pyrrophyta is the algae which is responsible for causing red tides that can kill thousands of fish.

As we know that Pyrrophyta is a division category of algae consisting yellowish green to golden brown algae.

They are mostly unicellular which form starch and its compounds, and oil as food reserves.

And it includes dinoflagellates which actually cause red tides that kill so many fish.

Hence, fourth option is correct.

the data of the detroit pistons in numerical order from least to greatest is 0.30, 0.37, 0.55, 0.62, 0.69, 0.72, 0.73, 0.75, 0.77, 0.78, 0.80, 0.81, 0.81, 0.83, 0.84, 0.89

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05

first one because it can't have a fraction in it
