Choose one animal species to study and write a summary of how they reproduce. Include the animal's age at puberty, recommended age for breeding, length of estrus cycle, length of ovulation, and length of pregnancy. Then write a one-page summary on this species' recommended breeding program and all the different things an animal producer must consider in breeding this animal over its lifetime.

Finally, list the barriers to fertility in this species and how they can be overcome.

Explanation:

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
