Answer:
Maintaining diversity ensures that species can continue to depend on one another.
Explanation:
its the real answer
1. Phenotypic
A phenotype is the physical representation of a gene. (Think Ph = Physical. That's how I remember it!)
2. Genotypic?
A genotypenis the gene. It is not seen physically.
3. Genes
Alleles are variant forms of a singular gene.
Answer:
a. 4 R¹R²
b. 4 Pink flowers
c. 1 Red, 2 pink and 1 white phenotypes
d. 1R¹R¹ : 2R¹R² : 1R²R²
Explanation:
This question involves a single gene coding for flower color in petunia plants. However, the allele for red flower color (R¹) is incompletely dominant over the allele for white flower color (R²), hence, a pink intermediate phenotype (R¹R²) is formed.
According to these questions;
A. If a white-flowered plant (R²R²) is crossed with a red-flowered plant (R¹R¹), all of the F1 generation will have a genotype of R¹R² (see attached image for punnet square).
B. The F1 generation, which possess a genotype: R¹R² will express the pink flower phenotype because neither of the two alleles are truly dominant over the other i.e incomplete dominance.
C. If two of the F1 offspring were crossed i.e. R¹R² × R¹R², each parent will produce R¹ and R² gametes. Using these gametes in a punnet square (see attached image), the following phenotypes will be produced in the F2 generation: Red, pink and white phenotypes
D. The F2 generation will possess a genotypic ratio of 1R¹R¹ : 2R¹R² : 1R²R².
Answer:
1. All volcanic eruptions are explosive
False
2. Volcanoes change the Earths surface constantly
True
3. Magma forms in the mantle
True
4. Volcanos are randomly located across the earth surface
False
5. Many volcanoes exist under the oceans
True
6. Volcanoes are only found in our solar system
False
Explanation:
1. Volancoes can also have effusive eruptions.
2. Volcanoes constantly change the Earth's surface in many ways.
3. The upper part of the mantle is where magma is formed.
4. Volcanoes are <u>not</u> randomly distributed over the Earth's surface.
5. There are many volcanoes under the ocean. Some rise half a mile above sea level.
6. There are volcanoes on the moons of Jupiter, Saturn, and Neptune.
Answer:
a) Individual pieces to a puzzle.
c) Bricks that makeup a house.
Explanation:
As stated, monomers are considered as a building blocks. They are arranged in a specific way to make a full structure. From the given options, both A and C are correct.
In the option A, individual pieces of puzzles acts as monomers to make the complete puzzle. The are arranged in a specific way to establish the complete structure.
In the option C, a home is made with bricks following some pattern. Therefore, each brick can be considered as a monomer and a home as a macromolecule.
