Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population.
Usually it is expressed as a proportion or a percentage.
In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool.
The frequencies of all the alleles of a given gene often are graphed together as an allele frequency distribution histogram.
Population genetics studies the different "forces" that might lead to changes in the distribution and frequencies of alleles - in other words, to evolution.
Besides selection, these forces include genetic drift, mutation and migration.
Phoresy is a smaller creatures that uses larger creatures to move large distances. Altruism is the behavior where an animal puts another's needs before their own. Commensalism is a beneficial relationship for one party and nutral to the other. Mutualism is beneficial to both parties.
The answer is Altruism.
Answer:B. is false
Explanation:
Once RNA polymerase and its related transcription factors are in place, the single-stranded DNA is exposed and ready for transcription. ... Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA.
1. Attraction for other polar molecules.
2. Stores heat, High specific heat!
3. Stores hear, High heat of Vaporization
4. Low density of Ice
5. HIGH POLARITY!
6. Water has high surface tension
7. Water has the ability to carry ELECTRIC current
8. Is a UNIVERSAL solvent= has the ability to dissolve so many substances
9. Water occurs naturally on earth in three forms; solid, liquid, and gas.
Answer:
D) It would contain less nitrogen.
Explanation:
In an investigation of the cycling of environmental gases, a student placed water and bromthymol blue in each of four test tubes as shown in the diagrams below. No additional items were placed in tube 1, a snail was placed in tube 2, an aquatic plant (elodea) was placed in tube 3, and both a snail and an elodea were placed in tube 4. The tubes were then stoppered and placed in bright light for 24 hours. The solution in tube 3 changes after 24 hours because it would contain less nitrogen.
The dfferent tubes are shown in the picture that I uploaded.
