Answer:
A RISK is the chance that someone or something could be harmed by a hazard.
Explanation:
Risk is the <u>probability of experiencing harm or an adverse side effect from exposure to a hazard</u>, may it be from the workplace, environment, or property.
Hazard is anything that may be a <u>source of possible harm or damage</u> to an individual or property.
Risks within the workplace are assessed to prevent workers from possible exposure or damage, this is called <u>Risk Assessment Control</u>. Here, the <u>likelihood of a hazard occurring is determined</u>.
An example is medication errors when the nurse/s are overworked.
<em>"Overworked nurses are 15 times (for example) more likely to commit medication errors than fully-rested nurses."</em>
The likelihood of developing such errors depends on multiple factors like:
<em>"Too much work load"</em>
<em>"Huge number of patients"</em>
<em>"Lack of manpower"</em>
tRNA-precursors were smaller than the modern tRNA and their primary function was to participate in the formation of new structures by joining two or more RNA molecules.
The adaptor hypothesis is the explanation of how information could be extracted from a nucleic acid into a string of amino acids in a specific sequence. The proposed explanation involved recognition between the adaptor (today tRNA) and the template nucleic acid .
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.
Bacteria cells have no nuclei.
hope this helps :)
