Answer:
1)The criteria pollutants are carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide. Criteria pollutants are the only air pollutants with national air quality standards that define allowable concentrations of these substances in ambient air.
2)Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with water.
3)By bringing national attention to water pollution issues, the Cuyahoga River fire was one of the events that led to the creation of the federal Environmental Protection Agency and the Ohio Environmental Protection Agency.
4)sry idk this one ☝️

Answer:
3. is activated immediately upon infection.
Explanation:
Innate immunity is the nonspecific immunity. These immune defenses are present at birth and do not involve specific recognition of a microbe. Being nonspecific in nature, it acts against all microbes. Innate immunity includes the first and second lines of defense.
Some of the examples of components of innate immunity among the first line of defenses are physical and chemical barriers of the skin and mucous membranes. Innate immune responses are the immunity’s early warning system that is generated immediately after the encounter with a pathogen to prevent them from entering the body and to help eliminate the ones that have entered the body.
Once a microbe has entered the body, secretion of antimicrobial substances and activities of natural killer cells, phagocytes, the process of inflammation, etc. serve to eliminate it from the body. All these responses are the components of innate immunity.
Probaly abiotic would be the most likely answer in my opinion.
Answer:
The type of treatment indicated to treat infertility due to blockage of the vas deferens is surgery to remove the obstruction (option C).
Explanation:
Blockage of the vas deferens is a known cause of obstructive azoospermia, which prevents the passage of sperm and causes infertility. This type of obstruction can be corrected by surgery, part of the treatment of infertility from this cause.
The vas deferens are in charge of conducting the sperm from the testicles to the ejaculatory ducts, which prevents these gametes from being expelled to fulfill their function in reproduction.
The other options are not correct because:
<em> A. </em><u><em>Medication to stimulate sperm production</em></u><em> does not resolve the blockage.
</em>
<em> B. </em><u><em>Hormone therapy to increase testosterone </em></u><em>could be considered for infertility treatment, but the obstructive problem continues.
</em>
<em> D. </em><u><em>Semen implantation in the testes</em></u><em> does not exist as a medical treatment.</em>
