Hemoglobin is the iron-bearing and oxygen-carrying component of red blood cells. The normal value for hemoglobin varies by age and gender. Anemia is generally considered when hemoglobin concentrations fall below 11 g/dL for pregnant women, 12 g/dL for non-pregnant women, and 13 g/dL for men.emoglobin is the iron-bearing and oxygen-carrying component of red blood cells.

A soil pipe is a PVC or cast iron pipe used in plumbing installations to remove soiled or contaminated water from toilets. Soil pipes differ from normal waste water removal pipes in that they are generally of a larger diameter and are designed specifically to remove solid waste from toilets.

Collect three samples of different local soils (or. make up âartificialâ soils). Aim for one clay-rich. soil, one sandy soil and one soil with larger. fragments like pebbles in it. Make three test funnels, by cutting three large (2. litre) plastic water bottles in half. Make a âsoil-fillâ. mark about 8cm from the neck of the bottle.
