True because it makes since and it’s a better answer than false
Answer:
Frequency of dominant allele is 0.9029
Explanation:
Total number of organisms = 12,845
Number of organisms representing dominant trait = 11,596. These organisms might have heterozygotes with one dominant allele and one recessive allele.
Hence, Number of organisms with recessive alleles = 12845 – 11596 = 1249
Frequency of recessive allele (q) = 1249/12845 = 0.0971
Frequency of dominant allele (p) = 1- q = 1- 0.0971 = 0.9029
Viruses cannot reproduce. they instead copy themselves with the help of a host cell. a cell can reproduce and doesn’t need help from other cells

The question is incomplete. Th ecomplete question is as following:
All of the following protect the skin and mucous membranes from infection EXCEPT
A) multiple layers of cells.
B) tears.
C) saliva.
D) HCl.
E) the "ciliary escalator."
Answer: D) HCl.
Explanation:
- The epidermis, the outer layer of the skin provides waterproofing and serves as a barrier to infection and other laers also sustain any type of injury.
- Tears wash out foreign bodies which enter the eye. In addition, tears contain a substance called lysozyme which has an antibacterial function and works to prevent microbial invasion and infection.
- Saliva protects against infection, especially via the innate immune system. This mechanism is an important first-line protection against bacterial and viral infection
- The mucociliar escalator is within the conducting airways and is composed of mucus and cilia that transfer the mucus up and out of the lungs where it can be removed by coughing or swallowing,
Whereas HCL helps in the digestion process.
Hence, the correct option is D.
