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.
The answer would be <span>B) </span>Sternomastoid and trapezius :)
Answer:
<u>Chloroplast</u>
The chloroplast is where photosynthesis occurs in plant cells. During photosynthesis, sunlight energy, carbon dioxide, and water are converted into simple sugars (glucose). These simple sugars are cell's version of food.
<u>Mitochondria</u>
The mitochondria is where cellular respiration occurs. During the process of cellular respiration, glucose, which is produced through photosynthesis in the chloroplasts, is broken down into cellular energy that can be used by the cell.
- Both chloroplasts and mitochondria are organelles that generate metabolic energy.

Answer:
staw or straw? But, never the less, normal insulation hurts the environment. while being manufactured, the factory's blow smoke. while straw/staw do not have to be built, so there for wont hurt the environment.
Explanation:
Ammonoids are good as index fossils because of the following characteristics;
<span>1.
</span>Their abundance and vast distribution across most shallow
marine waters during the periods
<span>2.
</span>They have easily recognizable
features, such as shells and the highly crenulated and complex suture, that are well preserved in rocks
<span>3.
</span>Their rapid
evolution that can assist determine changes and variations in the then environment
