The main structural difference between LDL and HDL is their compositions. Approximately 50% of the weight of an LDL particle is cholesterol and only 25% is protein. High-density lipoprotein particles, on the other hand, consist of 20% percent cholesterol by weight and 50% protein.
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.
