Organizing the Embryo: The Central Nervous System
In the embryonic development of a zygote, gradients of mRNAs and proteins, deposited in the egg by the mother as she formed it, give rise to cells of diverse fates despite their identical genomes.
Any foods grown without the use of chemical fertilisers or pesticides, in soil made rich by composting and mulching. Pertaining to carbon-based compounds produced by living plants, animals or by synthetic processes.
Organic compounds are compounds composed of carbon, hydrogen and often oxygen or nitrogen. Organic compounds are named so because they are associated with living organisms.

[Gr. organon - organ; Gr. genesis - origin, descent]. Formation of organs in the developing embryo.
An organ is part of the body which, forms a structurally and functionally separate unit and is made up of more than one type of tissue. Examples of plant organs are leaves, roots and stems.
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body.
The major organ systems of the body and their functions are the (1) integumentary system for protection, excretion, receipt of external stimuli (outer covering of skin); (2) muscular system for movement, posture, heat production; ...
(Organa Genitalia Muliebria)
The female genital organs consist of an internal and an external group. The internal organs are situated within the pelvis, and consist of the ovaries, the uterine tubes, the uterus, and the vagina.
A base is a chemical compound which can neutralize an acid. It can combine with a hydrogen from an acid. Organic bases are bases witha carbone backbone. Purines and pyrimidines are organic bases.
Organic molecules are those that: 1) formed by the actions of living things; and/or 2) have a carbon backbone. Methane (CH4) is an example of this.

The cell is a unit of organization
Cells are classified by fundamental units of structure and by the way they obtain energy.
centimorgan (cM) The metric used to describe linkage distances. A centimorgan is the distance between two genes that will recombine with a frequency of exactly one percent.
Beyond the role they play in internal cell movement, microtubules also work together to form larger structures that work on the outside of the cells.
A unit of measure of recombination frequency. One centimorgan is equal to a 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossing over in a single generation.
Organic compounds are compounds that are found in living organisms and contain carbon. Inorganic compounds are the ones that don’t contain carbon.

Organisms are physicochemical systems with a history shaped by evolutionary processes over the course of billions of years.
Even processes as amazing as dreaming and laughing are based on natural systems, and so can be studied scientifically.
Organisms get oxygen from their environment in a variety of ways. Many land animals breath oxygen directly from the air, while ocean bearing animals often use the oxygen dissolved in the water to survive.

Organisms are not passive targets of their environment. Each species modifies its own environment. At the least, organisms remove nutrients from and add waste to their surroundings. Often, waste products benefit other species.
organic Living or once living material; compounds containing carbon formed by living organisms.
organic compound A molecule that contains carbon, hydrogen, and usually oxygen.
ORGANIZATION: The living beings present a functional and structural organization. Both, structure and function, are narrowly interrelated.
Organ a structure within a multicellular organism that is made up different types of tissues working together to perorm a particular function, e.g. the stomach in a human or a leaf in a plant.
All organisms begin as a single cell, but multicellular organisms have programming to produce cells that have considerably different characteristics, even though the DNA is presumably identical. Kim, et al.
A central organizing concept in biology is that life changes and develops through evolution, and that all life-forms known have a common origin.

Mature male or female reproductive cell (sperm or ovum) with a haploid set of chromosomes (23 for humans).
Chromosome organized in nucleosomes composed of histones and other protein factors.
A group of organisms is said to have common descent if they have a common ancestor. All existing organisms on Earth are descended from a common ancestor or ancestral gene pool.
Genome: The total DNA contained in each cell of an organism. Mammalian genomic DNA (including that of humans) contains 6x109 base pairs of DNA per diploid cell.
Microbes are extremely small organisms that cannot be see without a microscope. Microbes are all around us. They can survive under some of the most extreme conditions, they are sometimes harmful to us, and they are essential to our survival.
Bacteria: Tiny one-celled organisms.
