You are camping in a canyon when a flash flood occurs and you are only able to grab some food before everything else washes away
. Hiking out of the canyon is your best chance for survival, so you need to pack light. You have waffle mix, maple syrup, cooking oil, candy, and a dehydrated sausage. In terms of caloric yield, which should you take to maximize your chance of reaching civilization before dying of starvation?
If the concept is to pack light then the way to go in order is
Waffle mix/candy
Sausage
Maple syrup/cooking oil
However this is not calorie efficient. If we were to pack in order of calories then we would have to consider the following
Waffle mix/candy: Carbohydrates provide 4 calories per gram
Sausage: Protein provides 4 calories per gram; fats provides 9 calories per gram
Maple syrup: Carbohydrates provide 4 calories per gram
Cooking oil: Fat provides 9 calories per gram
The most calorie dense is the oil and the sausage. Now we can eliminate the waffle mix and candy and maple syrup. Finally we are left with the dehydrated sausage and oil. While oil is more calorie dense it is heavier than the sausage. The dehydrated sausage also has more protein that will be needed to support muscle and tissue maintenance during the hike. Best choice under the circumstance is the dehydrated sausage.
Mitochondria are considered as the powerhouse of cell because they perform function cellular respiration process in a cell.
Cellular respiration is a process of converting the chemical energy present in nutrients into ATP which gives energy to organisms to carry out movement and physical actions.
Mitochondria performs cellular respiration process from which they can release energy present in food and nutrients.
Due to those reasons, mitochondria is called as powerhouse of cell.
The finches Darwin discovered are genetically different from other finches of the same species because of differences in habitat climate and the habitat itself.
