How do I fill a cell closest to break even without a deficit?
I am working on a homework assignment in excel. The directions on one of the steps says, "Apply a Red, Accent 2, Lighter 60% fill color to the cells closest to break-even without creating a deficit." How do I do this?
How long does it take for the human body to start breaking down fat for energy, while fasting?
Before you can start burning stored body fat, you need to deplete the liver’s glycogen stores as to signal the requirement for burning more energy.How fast you’re going to start burning body fat depends on the overall energetic demands and how fast you’re going to burn through that liver glycogen.There are 100–150 grams of glycogen in the liver which takes about 18–24 hours of fasting to be depletedExercising on an empty stomach makes you burn through liver glycogen faster thus allowing you to tap into your body fat stores faster as well. If you do fasted cardio in the morning you can start burning body fat within 12 hours of not eatingEating a low carb ketogenic diet allows you to deplete your liver glycogen while still eating. To lose body fat you’d still have to be eating at a caloric deficit but keto helps the liver tap into body fat fasterYour body starts breaking down stored fat for energy when it needs to compensate for a caloric deficit. That can happen by consuming fewer calories or burning more than needed for maintaining daily energetic requirements.That’s why you’ll be burning primarily your own body fat while fasting - you’re not eating (at a caloric deficit) and your liver glycogen is empty (take energy from body fat)My personal strategy includes:Eating a low carb ketogenic diet that maintains relatively low liver glycogen thus enabling me to start burning body fat faster.I also do intermittent fasting with one meal a day as to keep me in this fat burning more most of the dayLow intensity cardio and walking around throughout the day create a larger caloric deficit by simply moving aroundWorking out in a fasted state has a tremendous hormonal response for fat burning and longevityIn general, if I were to be eating a nice large meal the night before, I’d be burning body fat by the end of the next day.Here’s an article about - How Long Does it Take to Enter into a Fasted State After Eating - Siim LandStay EmpoweredSiim
How do trees carry water from the soil around their roots to the leaves at the top?
Trees do NOT get water to their leaves using cappilary action alone. Cappilary action could lift water to maybe 10 metres maximum. The tallest trees are over 8 times that height. Cappilary action plays only a small, albeit vital, role in lifting water in trees. The simple answer is that the tree uses the equivalent of a siphon effect to lift the water. A siphon works because water is cohesive, IOW water sticks to water. That cohesiveness of water in a siphon tube means that as water at one end falls it is able to suck more water up from the other end. Provided that the fall is greater than the rise you are trying to overcome you can use a siphon to lift water to significant heights. A tree trunk is basically composed of masses of siphon tubes filled with water, but it doesn't have any physical 'fall' component. Instead what the tree uses is the force generated by evaporation. As water enters a leaf it is exposed to the air and allowed to evaporate. Because water is cohesive that loss of water creates a negative pressure that pulls more water into the leaf within the leaf, and that in turn creates a negative pressure that pulls water into the vessel elements of the branch and the trunk. That pressure is sufficiently high to lift water to the tops of the tallest trees. Which is why trees use such massive quantities of water. Even a small tree will use over 100 litres of water a day and less than 1% of that will be used physiologically. The rest is simply evaporated off to draw more water up the stem. It's an incredibly wasteful process. This is also the reason why trees in dry environments are invariably shorter than plants in wetter environments. Because the system functions like a siphon the water column in the trunk can never be allowed to break or the pressure inside will immediately drop to zero. It's like getting vapour lock in a fuel line and plants can't re-prime the line. There has to always be sufficient water in the ground to feed the negative pressure required in the column. The taller the tree the greater pressure required and hence the more water required. As a result the maximum height of tree is determined in large part by the amount of water available.
