<u>Answer:</u>
<em>The correct option is Option B i.e. a mutation that leads to individuals with genetic differences.
</em>
<em></em>
<u>Explanation:</u>
The phenotype is the morphological character of an organism. Phenotype of a species depend on the genetic characteristics of the species itself, because all the characteristics are actually results of the genetic setup of the species.
So, a change in the genotype of the organism can bring massive changes in its phenotype. These genetic modifications are made up by the mutations.
The correct answer is hydrogen bond

<h2>The Cardiac cycle</h2>
Explanation:
Correct order is: 3,5,6,4,2,1,8,7
The cycle of events that happen in a single heart beat is called Cardiac cycle. Basically, it refers to repeated pattern of contraction and relaxation of the heart.The contraction of heart is called systole and the relaxation of heart is called diastole. The cardiac cycle includes systole and diastole of atria as well as systole and diastole of the ventricles. When heart rate is about 75 beats per minute, a cardiac cycle takes 0.8 seconds.
The order of events is cardiac cycle is :
- beginning of atrial systole
- completion of ventricular filling.
- beginning of ventricular systole.
- closure of AV valve.
- isovolumic contraction.
- opening of semilunar valve.
- ventricular ejection.
- ventricular relaxation.
