The four symptoms in the human body caused due to air pollution are:
•Itching and redness in eyes: This is a very common symptom easily seen in the people as an effect of air pollution. Redness and itching is caused due to inflammation in eyes.
•Coughing: Coughing is also caused due to inflammation in the bronchi. The mucosa secreted encounters some foreign materials and as a result of this coughing starts.
•Sneezing: The nasal passage has some mucosal secretion which when encounters the dust particles starts sneezing.
•Nausea: Some people feel nausea due to gases that causes air pollution
The four different symptoms in the human body that may be caused by air pollution are coughing, sneezing, nausea, redness and itching in eyes.
Further Explanation:
The addition of any harmful substance or gases mainly referred as pollutant into the air so as to change the natural composition of air is called air pollution. In this various solid, gases, or liquid particles releases in the environment. These pollutants are release into environment in the high concentration that affect health, aesthetic or economic effects.

Answer:
The correct answer would be 1) a person with AB blood type.
Codominance is the condition in which both the alleles of the gene express themselves completely in the heterozygous condition.
AB blood group can be a perfect example of the codominance. Both the alleles (A and B) express themselves completely and lead to the formation of protein A (or antigen A) and protein B (antigen B) on the surface of the red blood cells.
Statement 1 is true, Statement 2 is false, Statement 3 is false
1) Statement 1 is true. The fantasin gene will be transcribed at a high level when activators specific for control elements A, B, and C are present in the cell. These activators bind to the control elements and enhance the transcription of the fantasin gene.
2) Statement 2 is false. While general transcription factors are necessary for transcription in general, the specific control elements for each gene determine the level of transcription. So, the presence of general transcription factors alone does not guarantee high levels of transcription for the fantasin and imaginin genes.
3) Statement 3 is false. The imaginin gene will not be transcribed at a high level when repressors specific for the imaginin gene are present in the cell. Repressors bind to control elements and inhibit transcription, leading to reduced levels of transcription for the imaginin gene.

plz help. need this answered 4 science.
Answer:
Most ocean pollution begins on land.
Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff.
Answer:
Plastic pollution: The ocean is estimated to contain millions of tons of plastic debris, much of which comes from land-based sources.Chemical pollution: The ocean is also contaminated with a wide range of chemicals, including pesticides, herbicides, and industrial and household chemicals.Nutrient pollution: Excess nutrients, such as nitrogen and phosphorus, can enter the ocean from agricultural and urban runoff and contribute to the growth of harmful algal blooms.Oil pollution: Oil spills and other oil discharges into the water can have a negative effect on the animals and marine ecosystems there.
