Answer:
The letter B is the right answer.
Explanation:
The main objective of the hardin and Weinberg equilibrium is to determine how the allelic frequencies change within a population.
In 1908, Godfrey H. Hardy (1877-1947) and the German physician, Wilhem Weinberg, proposed that if no evolutionary factors act on a given population, the frequencies of their alleles would remain unchanged for several generations. This proposal became known as Hardy-Weinberg's Law (or theorem) or principle of gene balance.
According to this law, the necessary conditions for a population to reach equilibrium are:
a) The population must be large, so that all possible intersections occur.
b) The population must be panmatic (from the Greek pan, all, and from the Latin miscere, mix), that is, the crossings must be carried out randomly, without preconditions.
Within these conditions, without mutation, migration or selection, there will be a genetic balance. Over the generations, genes will not change.
there will be changes in the number of chromosomes
Answer:
As we move down the taxonomy ladder the group gets smaller and more specific.
Explanation:
- Taxonomy hierarchy is the classification system of organism developed by the Linnaeus.
- Linnaeus gave every organism its genus and species, forming a binomial nomenclature.
- The taxonomy ladder comprises of 8 ranks (domain, kingdom, phylum, class, order, family, genus, and species) that include the section from general to specific ones.
- So as we move down in the ladder system we can find more specific species in its classification.
Answer:
this is called reflect action
<span>The gas which was not prevalent in Earth’s atmosphere during the Hadean Eon is CO2. If you are going to see the composition of the Earth's atmosphere, Carbon Dioxide has the least percentage.
</span>This is because after the hydrogen and helium had escaped, Earth's Hadean atmosphere was left with methane, ammonia, water vapor, and small percentages of nitrogen and carbon dioxide.
See attached file for further information about the Earth's atmosphere during the Haedan Period.
