The process of heart contraction stimulates by the initiation of an electrical impulse. This electrical impulse starts in the SA node.
<h3>What is the Heart contraction?</h3>
Heart contraction may be defined as a type of physiological activity that stimulates electrical impulses which are initiated by the sinoatrial node. Systole is significantly the contraction phase of the cardiac cycle.
The SA node is a small bundle of specialized cells that is remarkably located in the right atrium. The electrical activity escalates through the walls of the atria and induces them to contract. This action finally forces blood into the ventricles.
Therefore, the SA node is responsible for the initiation of impulses that stimulates heart contraction.

Explanation:
Assuming her weight loss is going to happen through nutrition alone. This question can be answered if we make apparent a few points. One pound is equal to 3500kcals. Jackie needs to lose 15lbs in 3 months. Therefore, she really needs to lose 52,500kcals (15lbs x3500kcals). In 3 months this equates to a caloric deficit of approx 584kcals/day (52,500kcals divided by 90days). So in order to reach her target goals she’s needs to be in a caloric deficit of 584kcals a day for 3 months from her current caloric intake that permits the maintenance of her body weight.
Answer:
The reason for the lack of expression might be as follows:
- The difference in the presence of promoter in case of prokaryotes and eukaryotes might result in the gene expression. The RNA polymerase present in prokaryotes cannot recognise the sequence of the eukaryotes.
- The lack of kozak sequence also lacks in the result of the gene expression.
- The difference in the transcription factors in prokaryotes and eukaryotes results in lack of gene expression.
- The termination process is also different in prokaryotes and eukaryotes.
