Answer:
C) esophagus - moves air from the nose into the lungs
Explanation:
The oesophagus is a muscular tube with a sphincter valve at each end. Its main function is to transport food and fluid, after being swallowed, from the mouth to the stomach.This is propelled from the pharynx into the oesophagus, and towards the stomach in a peristaltic waves. The peristalsis also pushes food along the alimentary canal
By water and eggs took the test on edge it’s B
Answer:
Cytokines made by other innate cells, such as macrophages or dendritic cells
Explanation:
Innate Pattern Recognition Receptors (PRRs) on Dendritic cells and macrophages sense and respond to PAMPs and produce cytokines. Cytokines start the innate immune response.
The cytokines are produced in response to pathogen-associated molecular patterns (PAMPs) such as peptidoglycan monomers or CpG sequences on bacterial and viral genomes. Cytokines produced in response to pathogen receptors on cell surfaces, such as the inflammatory cytokines IL-1, IL-6, IL-8, and TNF-alpha, chemokines and type I interferons that act on leukocytes so as to promote and control early inflammatory responses.

Answer:
The relationship between an organism's DNA and protein specificity is that DNA determines the amino acid sequence of each protein (option D).
Explanation:
Each organism's DNA molecule is formed by a specific sequence of nitrogenous bases that not only determine the amino acids that a synthesized protein will have, but also the order in which these amino acids will form the protein structure.
The steps in which this occurs can be summarized as follows:
- <em>The sequence of nitrogenous bases of a DNA strand is transcribed into the mRNA, which will go into the cytoplasm.
</em>
- <em>The sequence of bases in the mRNA is organized into triplets of bases, called codons, each of which encodes a specific amino acid.
</em>
- <em>During translation, each codon will indicate the amino acid that will be coupled to a protein molecule in a specific order.
</em>
According to this, the<u> DNA </u><u>determines the </u><u>amino acids sequence</u><u> that will be in a </u><u>specific protein</u><u> molecule</u>.
