Answer:
Respiratory disease high above the national average.
Explanation:
Particulate pollution also known as particulate matter is a mixture of liquid and solid droplets that is suspended in the air. These particles include dust, dirt, soot, smoke, and liquid droplets.
Particulate matter is derived from cars, factories, construction sites, unpaved roads, and also burning of wood and fossil fuels.
Particulate pollution have harmful effects on the human body. It could lead to respiratory symptoms such as irritation of the airways, coughing or difficulty breathing.
Answer:
DNA vaccines consist of DNA vectors or plasmids (small double-stranded DNA rings originally derived from bacteria, but unable to cause infection) into which the genes encoding one or more immunizing proteins of the infectious agent have been inserted causing the disease to be prevented.
Explanation:
Vectors are the functional unit of naked DNA vaccines. Genes that encode the proteins of interest and are of bacterial origin are inserted into these vectors. Bacterial plasmids are circular DNA molecules that self-replicate extrachromosomally in bacteria. The genes encoded in these plasmids are under the control of promoters, almost always of viral origin. When a plasmid is introduced into the cell it translocates to the nucleus, where transcription of the transgene begins; the transcripts are then taken to the cytoplasm and translated there. The newly synthesized proteins are degraded in the proteasome to 8-10 amino acid peptides, which are transported to the endoplasmic reticulum. Peptides of high affinity with their respective MHC I molecule stabilize and enter the secretory pathway, thus reaching the cell surface, where they are coupled with the T-lymphocyte receptor (TcR) present on the surface of T lymphocytes cytotoxic drugs (CD8 +) to induce their activation.
The heterozygous birds phenotype would therefore be black and white because both parent genes are dominant so they would be fully expressed,none would overpower the other(no dominant or recessive) this is known as Codominance and and example of this is with the blood types.
