Answer:
The answer is: option I, II and III (i.e I. increasing the turbidity and cloudiness of the water.II. reducing sunlight penetration and thereby decreasing productivity of aquatic plants. and, III. clogging gills of fish and bottom dwellers.
Explanation:
Activities such as road construction, building construction, logging, remove the protective vegetative covering from soils. As a natural part of the ecosystem, and, formed by the most common mineral that is found on or near the surface of the Earth, Sediments classified by origin are of four types: cosmogenous, hydrogenous, lithogenous and biogenous. Sediment is fine-grained particles like silt and clay that is broken down by processes of weathering and erosion. Wind, force of gravity acting on the particles, water and ice help carry these particles to rivers, lakes and streams.
Sediment increases the potential for flooding. Loose sediments are washed into the streams with surface water runoff during rain storms
Some of the ways sediment pollution affects the waterways is by:
- Making the water cloudy, thereby preventing visibility in water. Even, animals in the water are prevented from seeing food.
- Sediment can clog fish gills, affecting fish egg and larvae development.
- High levels of turbidity limit penetration of sunlight into the water, thereby depriving the aquatic plants from sunlight needed for optimum productivity.
Answer:
Here are four reasons someone may not be ready to be a parent, due to emotional immaturity.
1-no consistent income (not mature enough to stick with a job)
2-no steady relationship (this is not an ideal environment for a child)
3-selfishness (being a parent means giving up much of your life for your child. If someone is emotionally immature they may not be ready to take this on)
4-focus on appearances (being pregnant is not a beautiful look, and if someone is immature they may be concerned about their appearance)
You need a bachelors degree in any health related field, complete a doctor of physical therapy degree program, meet your state licensing requirements, complete a residency (optional), obtain board certification (optional)
Small pores called gastric pits contain many exocrine cells that secrete digestive enzymes and hydrochloric acid into the lumen, or hollow region, of the stomach. Mucous cells found throughout the stomach lining and gastric pits secrete mucus to protect the stomach from its own digestive secretions.
