The Earth is closest to the Sun, or at the Perihelion, about two weeks after the December Solstice, when it is winter in the Northern Hemisphere. Conversely, the Earth is farthest away from the Sun, at the Aphelion point, two weeks after the June Solstice, when the Northern Hemisphere is enjoying warm summer months.
Mitochondria are essential components of nearly all cells in the body. These organelles are the powerhouses for cells, providing energy to carry out biochemical reactions and other cellular processes.Mitochondria make energy for cells from the chemical energy stored in the food we eat.itochondria are essential components of nearly all cells in the body.

The organelle responsible for energy production inside a cell is called a Mitochondrion (Plural: Mitochondria). These pill shaped organelles take food and break it apart into water and carbon dioxide. As food is broken down, an enormous amount of energy is created. Think of the power generators that produce electricity for our cities. As these power generators break up fuel, they create electricity which is captured and transmitted throughout the city. Within living things, cells which are more active need more energy. As a result, these cells have more mitochondria.
