In the sentence "The F2 generation phenotypes resulting from the
monohybrid cross of purebreds display a ratio of _____" the word that
correctly completes the sentence is 3:1. In the monohybrid cross of
purebreds, F1 generation will consist of heterozygotes with dominant
phenotype. When F1 generation cross, the F2 generation phenotypes will
be as following: 3 dominant phenotypes (1 dominant homozygote and 2
heterozygotes) and 1 recessive phenotype (1 recessive homozygote).
Explanation:
As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.
- Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
- Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
- Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
- High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.

Answer:
You are correct it's the earth!
Explanation:
The reason why is because, the term "elliptical orbit" is used in astrophysics and astronomy to describe an oval-shaped path of a celestial body. The Earth, as well as all the other planets in the Solar System, follow this type of orbit around the Sun. The shape is created by the varying pull of forces, such as gravity, on two objects, such as the Sun and a planet.
