Energy fuels your body's internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Water, your body's most important nutrient, helps facilitate the chemical reactions that produce energy from food. We need energy to perform functions such as growth, maintaining balance, repair, reproduction, movement and defense. This means all living organisms must obtain and use energy to live and survive.

Petrochemicals also called petroleum distillates are chemical products derived from petroleum and natural gas. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as corn or sugar cane.

Genetic traits can be passed through families in several distinct patterns. The most common patterns are the following:

Dominant genetic diseases are caused by a mutation in one copy of a gene. If a parent has a dominant genetic disease, then each of that person’s children has a 50% chance of inheriting the disease.Examples of dominant genetic diseases include Achondroplasia and Huntington disease

Recessive genetic diseases. When both parents are carriers of the same recessive disease, there is a 25% chance that the pregnancy will inherit the trait from both parents and have the disease, a 50% chance that the pregnancy will inherit the trait from only one parent and be a carrier, or a 25% chance that the pregnancy will not inherit the trait from either parent and will not be a carrier or have the disease.

Chromosome abnormalities can occur in any pregnancy. Sometimes these risks are related to the parent’s age and involve extra or missing chromosomes.

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells.In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Cell death are of two types: Necrotic and apoptotic.

Necrotic means the cell dies due to some sort of outside stimulus. Mechanical stress, lack of oxygen, etc. This is a more or less unregulated process, and so the cell bursts open and releases its cytoplasm, possibly causing damage around it. It's usually not entirely unregulated.

Apoptotic means that the cell was programmed to die, because it was part of a phase now gone in embryonic development, because it has been overproduced, because there aren't any growth factors around, etc.The cell starts dividing itself up into smaller "blebs", which can be digested by macrophages and the like without any tissue damage. It's an incredibly clean process, compared to necrosis.

Semi-synthetic fibers are fiber that are derived from originally naturally-occurring fibers, usually with the addition or treatment by synthetic chemicals. Examples of a semi synthetic fiber are Rayon(viscose),artificial silk,acetate etc.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy.It is the process by which green plants and some other organisms use sunlight to synthesize nutrients(carbohydrate) from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

The rule in neuroscience is "use it or lose it"
Brain is way too expensive to maintain unless it contributes to overall functioning. . So you use 100% of whatever you have

The myth of 10% originated with the studies of Karl Lashley, who was searching for the memory engram in the brain. He taught many rats to navigate a maze. In each group he removed a different potion of brain and then tested the rats on the maze.

If the rat could perform, he enlarged the size of the lesion

An organism of microscopic or submicroscopic size, especially a bacterium or protozoan.An organism that can be seen only with the aid of a microscope and that typically consists of only a single cell.
