A male common tern catches a fish, carries it back to too its bird colony, and displays the fish to female common terns. The female common tern that accepts the fish will often form a pair with a male common tern who presented the fish. Why does the male tern show this behavior? PLEASE HELP ME NOW! thanks

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

b.

the accuracy of the data.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
