A !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
b. Even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.
Explanation:
There is redundancy in the genetic code. That means that different codons can code for the same amino acids, so some mutations do not change the amino acid sequence of the protein.
Here, the amino acid is unchanged with the mutation.
If the amino acid sequence of the protein is the same, then the protein is not changed, so there will be no change in the phenotype
D. Lymph nodes are the filtering points throughout the body... found in the lymphatic system
Answer:
Type II cells
Explanation:
Type II alveolar cells are the round-shaped or cuboidal epithelial cells. These cells have a free surface with microvilli. The function of the type II alveolar cells is to secrete the alveolar fluid to keep the surface of the cells moist.
A mixture of phospholipids and lipoproteins is present in the alveolar fluid that serves as surfactant and reduces the surface tension of the alveolar fluid. The overall effect of the presence of surfactant in alveolar fluid is to protect the alveoli against collapsing during exhalation.
