Some organisms have genes that improve their ability to survive and reproduce. If the gene also help their offspring survive and reproduce, then frequency in gene in population get increase.
<h3>
What is gene?</h3>
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA and each chromosome contains many genes.
Throughout the individual lives, their genomes interact with their environments to cause variations in traits which help an organism to adapt better to the environment. These changes which help the organism's survival are selected and passed on to next generation. The genes help in increasing the fitness of the organism and thus the gene frequency changes. . The frequency of these gene increases as they are selected favourably.

Amino-acid racemization is primarily used to date samples of bones, applicable beyond the time of range of radiocarbon dating. Amino-acid Racemization, the AAR rates not only change of the temperature but also with the concurrent effects of pH changes. L-amino acid is an example of racemization which is the process <span>in which one enantiomer of a compound.</span>
Here is the complete statement: Linoleic acid is a polyunsaturated fatty acid found in PLANT OILS.
Linoleic acid is a polyunsaturated essential fatty acid that is used in the biosynthesis of prostaglandins and cell membranes. It can be found in plants glycosides (it is especially plentiful in canola oil) in natures and it is an essential fatty acid that humans need in their diets. In humans, linoleic acids are found majorly in the brain and in the retina. The acid is very important for brain growth and development especially in children.
The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
Biodiversity is the most complex feature of our planet and it is the most vital.
Two human actions that contribute to the loss of biodiversity are:
1. Forest clearing
2. Wetland filling
3. Stream channeling and rerouting
4. Road and building construction
These are often part of a systematic effort that produces a substantial change in the ecological trajectory of a landscape or a region. As human populations grow, the terrestrial and aquatic ecosystems they use may be transformed by the efforts of human beings to find and produce food, adapt the landscape to human settlement, and create opportunities for trading with other communities for the purposes of building wealth. Biodiversity losses typically accompany these processes.
