Muscle cells, also known as myocytes, contain numerous amounts of mitochondria inside of their cytoplasm. Mitochondria are organelles that are popularly known as the powerhouse of the cell because they function to process different biochemicals (such as glucose, oxygen, etc) and produce essentially Adenosine Triphosphate (ATP). Kreb's Cycle in particular talks about energy production, and the mitochondria is one of the main units where this cycle happens. You can think of ATP as the currency of the body in terms of energy. The more ATP one has, the more energy there is available for use by the different systems of the body. Muscles in particular have high demand for ATP.
The answer is <span>2.4 weeks
</span>
<span>x - the time in weeks
y - the heights of the plants in inches
</span><span>When both plants to reach the same height, then yA = yB
</span><span>y = 1.8x + 3.1
</span><span>y = 2.3x + 1.9
</span>2.3x + 1.9 = 1.8x + 3.1
2.3x - 1.8x = 3.1 - 1.9
0.5x = 1.2
x = 1.2 : 0.5
x = 2.4
The new hypotheses proposed by different scientists are often criticized by the others because these new hypotheses contradict the ideas and hypotheses that already exist. Adapting one's mind to a new hypotheses explaining a past event is often difficult when more clear hypotheses were already given earlier. Thus, the hypotheses suggesting the extinction of the dinosaurs are difficult for the scientific community to accept.
