Select the two terms that correctly complete this statement. Observable traits exhibited by an organism do not always indicate the exact genetic makeup of
that organism because of recessive alleles and <span>polygenic traits</span>.
The answer would be B i believe<span>(a protease) begins the chemical digestion of protein</span>
<span>Sponges have cellular-level organization, meaning that that their cells are specialized so that different cells perform different functions, but similar cells are not organized into tissues and bodies are a sort of loose aggregation of different kinds of cells. This is the simplest kind of cellular organization found among parazoans.

Answer choice: [C]:
_________________________________________
V = d / t = 1800 mi / 40 min = 180 mi / 40 min = 45 mi / min .
Which very well could be "Answer choice: [C]: 45 m/min" ; except, this answer choice may have been written incorrectly—and should read:
"45 m/min."
________________________________________________________
Now, notice that all the answer choices given are in "meters" per (unit time—seconds or mins.
So, we need to convert:
45 mi. to "meters", or "m".
______________________________________
Note the following conversions:
_______________________________________
1 mi. = 1750 yd
______________________________________
3 ft. = 1 yd.
____________________________________
1 m = 3.2 ft.
_____________________
So, 1 mi. = ? m ;
_____________________
1 mi * ( 1760 yd/ mi) * (3 ft / 1 yd) * ( 1m / 3.2 ft) = _?_ m ?
_____________________________________________________
On the "left hand side" , the units of "mi", "yd", and "ft" ; cancel to "1" ;
____________________________________________________
and we are left with:
______________________________________
[(1760 * 3)] / [(3)*(3.2)] m = (5280 / 9.6) m = 550 m .
______________________________________________
So, we have: 550 m / min ; which match NONE of the answer choices.
However, it is possible that choices A or B, which are given in "m/sec" (meters per second); are among the correct choices.
____________________________________________
So, we convert: 550 m / min to: "m / sec " ;
______________________________________
( 550 m/ min)*(1 min/ 60 sec) = (550/60) m/sec = (55/6) m/ sec
= 9 1/6 m / sec .
_____________________________________________________
which is: None of the above.
______________________________________________________
Unless the answer choices were written incorrectly.
