The probability that neither of them is a heavy smoker is 0.53 or 53%
<h3>What is genetic probability?</h3>
Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.
In this case:
Probability that selected one is heavy smoker is:
p=270/1000=0.27
Number of individuals selected is 2 and We know that:
P(X=x)=nc_x(1-p)^{n-x}(p)^x
We need to prove that X=0:
P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0
P=0.5329

Answer:
The current answer is a. Bacterial culture
Explanation:
Bacteria are used in epidemiology laboratory and bacteria can spread and cause disease if the correct lab procedures are not followed.
So according to the lab safety sheet bacterial culture is the potential hazard that will be present in the laboratory during the Epidemiology & Laboratory Techniques lab. There are different levels of biosafety according to the threat posed by the bacterial culture on which epidemiological study is going on.
The biosafety sheet helps in featuring the epidemiology of bacterial culture, transmission mode, availability of medical interventions, suggested biosafety levels, etc. So the right answer is a.
Answer:
Are all genes active at the same time?
Thanks to gene regulation, each cell type in your body has a different set of active genes—despite the fact that almost all the cells of your body contain the exact same DNA.

reason:
salt is not involved and no osmosis occurs
Answer:
A line of thunderstorms in the provides moisture and nitrogen to the crops. The energy in the lightning breaks the N2 molecules apart so they can combine with the oxygen to make nitrogen oxides that can be dissolved in the rain. These forms of nitrogen are essential nutrients for plants. Rain from these storms provide far more to the crops than an equal amount of irrigation can do.
