What is Life?
Introduction
In this chapter we will learn how living organisms change as they become better adapted to their environment. Over billions of years, these changes have produced a large number of different kinds of organisms.
12. A history of the acts and events of a life; a biography; as, Johnson wrote the life of milton.
13. Enjoyment in the right use of the powers; especially, a spiritual existence; happiness in the favor of God; heavenly felicity.
diploid life cycle -- Occurs when the only multicellular stage in an organism's life cycle is diploid.
Life is studied at the atomic and molecular scale in molecular biology, biochemistry, and to molecular genetics. At the level of the cell, it is studied in cell biology and at multicellular scales, it is examined in physiology, anatomy, and histology.
Life.
Look around you. What do you see? A classmate, a brother or sister? Look out the window, or go for a walk. You will see trees, grass, plants, dogs, cats, bugs, and many other forms of life.
Life insurance is essentially a contract in which the insurer agrees, in exchange for a specified premium, to pay a determined amount of money to designated beneficiaries upon the death of the insured.
"What is life?"
"When can we say that a system, or a subsystem, is alive?"
"What is the smallest system that we can consider alive?"
"Why is nature able to achieve an open-ended evolutionary system, while all human models seem to fall short of it?
The case for life on Mars — whether today or in the past — is neither proven nor disproven. Stay tuned! ...

Life Before a Nucleus
Not all cells have a nucleus. Biology breaks cell types into eukaryotic (those with a defined nucleus) and prokaryotic (those with no defined nucleus). You may have heard of chromatin and DNA.
life cycle
The entire sequence of stages in the life of an organisms, from the adults of one generation to the adults of the next.

Life in Water
Coral, decimated by Paleozoic extinctions, rebounded during the Triassic with the evolution of the scleractinian corals. Dinoflagellates made their first appearance as part of the phytoplankton.
life history The age at sexual maturity, age at death, and age at other events in an individual's lifetime that inþuence reproductive traits.
Life Cycle: The sequence of events that occurs during the lifetime of an individual organism.
Maggot: The immature form (larva) of a fly or wasp, lacking legs and a well-developed head.
Life table: A table summarizing statistics of a population, such as survival and reproduction, all broken down according to age classes.
Litter: Accumulations of dead leaves in various states of fragmentation and decomposition.
Charmed Life
The hoax had a charmed life. Features that might have exposed the hoax didn't get caught because of small errors in procedure.
Life is a delay of the spontaneous diffusion or dispersion of the internal energy of the biomolecules towards more potential microstates.
Life expectancy in Africa rose from 44 years in 1950 to 59 years by the late 80s, and is now expected to return to under 45 years.

Revised "tree of life" with all groups divided into their domains. Includes information about lateral gene transfer and the endosymbiosis of bacteria that became mitochondria and chloroplasts.
In early life it has a glandular structure which reaches its greatest development at about the seventh year. Later, especially after puberty, the glandular tissue gradually disappears and is replaced by connective tissue.

Taxonomy
Biomes
Biomes are the world's major habitats. These habitats are identified by the vegetation and animals that populate them.
Extremely small and simple life forms made merely of a protein shell and a genome. A virus reproduces by inserting its genome into the cells of other life forms. As those cells duplicate, so does the virus.

Cell: The lowest denomination of life thought to be possible. Most organisms consist of more than one cell which becomes specialized into particular functions to enable the whole organism to function properly.
The evolutionary development of similar external morphological traits in organisms which are unrelated (except through distant ancestors) as each adapts to a similar way of life and/or environment.
Biology the study of life

Bioluminescence production of light by living organisms
(bios = life; lumin = light) ...
photosynthesis - use of light to carry out reductive biochemical processes necessary for life. Pigments capture light energy in much the same way as an antenna captures a radio or tv signal. This drives biochemical reactions.
Interphase (IN-tur-faze) A period in a cell's life cycle when it is not undergoing mitosis.
Lipid (LIP-id) A fatty, waxy, or oily compound that will not dissolve in water. Lipids are a major part of biological membranes.
Lytic. A phase of the virus life cycle during which the vi- rus replicates within the host cell, releasing a new generation of viruses when the infected cell lyses.
M
Malignant. Having the properties of cancerous growth.
The relative reproductive success of a genotype as measured by survival, fecundity or other life history parameters. See Darwinian fitness and natural selection.
