Answer:
Globular cluster
Explanation:
A globular cluster is a spherical collection of stars. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and high stellar densities toward their centers.
Answer:
generation 1
Explanation:
The allele frequency is a term that represents the frequency that an allele can appear in a given population. This term can help to develop conclusions about the genetic diversity that a region presents in relation to the individuals that compose it.
In relation to the question above, generation 1 had the highest frequency of having one of each allele. This is because this generation presents the maximum frequency of the dominant and recessive alleles in a coherent way, 0.60 and 0.40. However, the other generations showed a steady and progressive decrease in the recessive allele.
These include the chemical. cellular. tissue organ. organ system and the organism level
Perhaps the answer is "physical characteristics". I am simply making an educated guess, however I do know early philosophers classified organisms into two groups, Plants and Animals, and identified them based on physical characteristics.
