Answer:
Phenotype: 2:2 or 1:1 / Genotype: 2:2 or 1:1 / 50% probability for chestnut color
Explanation:
If we put the two horses' genotypes in a Punnett square:
<u> B b</u>
<u>b</u> Bb bb
<u>b</u> Bb bb
The phenotype is describing the ending color of the offspring, where 2 of the 4 will be brown (Bb) and 2 of the 4 will be chestnut (bb), resulting in a 2:2 ratio. Genotype only refers to the alleles, where 2 of the 4 will be hybrid (Bb) and 2 of the 4 will be homozygous recessive (bb), again resulting in a 2:2 ratio. There is only a 50% chance that the offspring's phenotype will be chestnut color (bb) because the chestnut allele is recessive.
Charles Darwin also was the first biologist to propose the use of the phylogenetic tree or the evolutionary tree. The phylogenetic tree illustrates how organisms are related, usually by traits. It also represents how organisms are related by common ancestors. Other scientists refer to the phylogenetic tree or parts of the tree as a cladogram.
Attached is an example of a simplified phylogenetic tree.
Hi
Guam is an unincorporated territory of the United States which means that the area donot posses its own municipal government. This lies within the administrative and political jurisdiction of own area. However, they still are the citizens of United States.
The indigenous people of the Guam Island are called Chamorros and mainly they speak English and Chamorro languages. The people are US citizens.
Because of being an unincorporated territory , the citizens are facing several problems that should be resolved. Such as:
- The social and legal rights of Indigenous people.
- Illegal usage of drugs because there are no proper established laws.
- Land ownership issues.
- Unrestricted immigration in the Island because of lack of laws.
- Domestic violence
Scientists face these issues when they want to study the life at island of Guam.
Hope it helps!

- is returned to the earth by decomposers
Explanation:
Animals do not possess any sort of cell wall since animals always move, they are not static in one particular place, therefore they need to be flexible.Animal cells lack the thick cell wall that plant cells have, so there is no need for a central vacuole to exert pressure on the surrounding cell
