Net energy expenditure is more important because it represents the energy that is actually available for the body to use after accounting for energy lost as heat during metabolism. Gross energy expenditure includes all energy expended, both useful and wasted, providing a less accurate picture of the body's true energy needs. Focusing on net energy expenditure helps in understanding how much energy is actually available to fuel physiological processes and activities.

What is energy balanced?
Energy balance can be described by this equation : Energy intake = internal heat produced + external work + energy stored.
What happens if you take in more energy than you use day after day?
If you consistently consume more energy (calories) than you expend, you may gain weight over time. This excess energy is stored as fat in the body, leading to weight gain and potentially contributing to health issues such as obesity or related conditions. It's important to maintain a balance between energy intake and expenditure for overall health.
Why would you use more kinetic energy running up a hill than walking up?
Running up a hill requires more force to overcome gravity and friction compared to walking, therefore more kinetic energy is needed. Running also involves larger muscle contractions and faster movements, leading to a greater expenditure of energy.
How does your bodies store unwanted energy?
The body stores unwanted energy in the form of fat. When we consume more calories than we burn through daily activities, the excess energy is stored in fat cells for later use. This can lead to weight gain and health issues if the energy intake consistently exceeds the energy expenditure.
Do you use more energy when you are hot or cold?
The body generally uses more energy when it is cold because it needs to work harder to maintain its core temperature. In cold conditions, the body must use energy to shiver and generate heat to stay warm, resulting in increased calorie expenditure.
Why is it important that your energy intake measures up with your energy expenditure?
Because if your intake is bigger than your expenditure you will begin to gain weight.On the other hand,?if you spend more energy than what you intake, you will be spending your body's energy reserves. If you are overweight, this may actually be desirable - for a while. But this is not something that can be sustained in the long term - eventually, you will finish up your reserves.

Which energy is more important electrical energy or chemical energy?
They are both very important!!!!

How do hogs fatten?
They are fed lots of food more calories in means fatter animals. It is also possible to reduce their energy expenditure by restricting their movements, for example by keeping them in small spaces. It is also possible to reduce their energy expenditure by keeping them warm for example in a heated indoor enclosure.
Given that a nonpolar substance is more concentrated outside of a cell how does it get across a cell's plasma membrane without the expenditure of energy?
Osmosis and diffusion.
What event makes the hypothalamus sense that body cells need more energy?
A decrease in glucose levels in the blood signals the hypothalamus that body cells need more energy. This triggers the release of hormones that regulate appetite, metabolism, and energy expenditure to maintain energy balance.
Where do heat get energy from?
For one thing, heat is a radiant form of energy. When atoms and molecules have energy, they oscillate at a certain rate. Due to this movement, there is energy expended, and one of the byproducts of this expenditure is thermal radiation, heat being of that category. The more energy in process within atoms and molecules, the more thermal radiation, i.e. more heat.
How does a polar substance get across a cells plasma membrane without the expenditure of energy assuming it is more concentrated outside of the cell?
it goes in straight lines
Why is it important to achieve a high gross margin?
The higher the gross margin the more profit you can make. Gross margin is the difference between cost and original sell price of a product. it is you the original conceived profit. Obviously the higher the gross margin the more profit possible. (That is as long as a customer will pay that price!!)
What is essential expenditure?
essential expenditure is the items you really need such as water, food, boiler and many more none essential expenditure are stuff like game consoles, expensive clothes, bikes, cars and many more.
Is depreciation revenue expenditure?
Yes depreciation is a revenue expenditure as it incurs every year to generate revenue and capital expenditure is that expenditure which is incurred for one time to earn revenue for more than one fiscal year.
