A neutron is combined in a nuclear reaction with a proton to make a heavy hydrogen nucleus. This nucleus then acquires _____ ele

sergeinik [125]

Answer:

This nucleus then acquires <u><em>one </em></u>electron to become electrically neutral.

Explanation:

Fusion :It is nuclear reaction which two or more than smaller nuclei combines together to form heavy nuclear.

A neutron combines with proton in order to make heavy electron that is fusion reaction is taking place.

$^{1}\textrm{n}+^{1}_{1}\textrm{H}\rightarrow ^{2}_1\textrm{H}+$

The overall charge in the nucleus will be +1.And in order to neutralize this positive charge the nucleus will acquire single electron to become electrically neutral.

How is the end result of spherocytosis similar to sickle cell disease?

Nikolay [14]

A geneticist is studying two genes. each gene can be either dominant or recessive. a sample of 100 individuals is categorized as

Aleksandr-060686 [28]

Attached is a table. I found the exercise on another page on the internet and the sample of 100 individuals was categorised on a table - easier to understand than as it is presented here.
<span>"(a) what is the probability that a random sampled individual, gene 1 is dominant" - We should first add up all of the individuals that are dominant for gene 1 (56+24) and then divide it by the total number of individuals (100).
</span> $\frac{56+24}{100}$ =0.8
<span>The probability is of 8 in 10 individuals.
"</span><span>(b) what is the probability that a random sampled individual, gene 2 is dominant" - Follow the same logic as in the previous question.
</span> $\frac{56+14}{100}$ =0.7
<span>The probability is of 7 in 10 individuals.
</span>"<span>(c) given that gene 1 is dominant, what is the probability that gene 2 is dominant" - Because we are considering those that are dominant for gene 1, our total number of individuals is the total individuals that are dominant for gene 1 and not the whole 100. Once we have this restriction, and we want to know the probability that gene 2 is dominant in these individuals, we should also only consider those that are dominant for gene 2.
</span> $\frac{56}{56+24}$ =0.7
The probability that gene 2 is dominant, given that that gene 1 is dominant, is of 7 in 10 individuals.
