Answer:
To maintain this balance, the Hardy-Weinberg Equilibrium Principle states that a population should meet five main assumptions. There should be random mating, large population size, no mutation, no selection on the gene in question, and no gene flow in or out of the population.
Explanation:
I am thinking the rock that forms from lava that cools quickly is D) Obsidian.
The correct answer is B. 1 red; 2 pink; 1 white
Explanation:
In genetics, the combination of alleles (genotype) determines the phenotype or physical features; for example, in this case, the color of the flowers in the snapdragon plants can be determined by the combination of dominant alleles (R) and recessive (r) alleles. Additionally, in the case presented, a dominant allele combined with a recessive allele (Rr) leads to pink snapdragon plants, while two dominant alleles (RR) lead to red snapdragon plants, and two recessive alleles (rr) lead to white snapdragon plants.
According to this, the generation F2 shown in the chart produced 1 red plant because there is only one plant with RR genotype; 2 pink plants because there are two plants with Rr genotype; and finally one white plant because the last plant has an rr genotype.
B. Cell wall and a central vacuole
The cell wall is a rigid structure that surrounds the cells and allows plants to stay upright. Animal cells are more fluid.
The central vacuole is a large region in the cell that stores nutrients and fluids. Many cells, including animal cells, contain vacuoles, but most are small, and only plant cells contain large central vacuoles.
Hope this helps!!
