Dead zones are low-oxygen areas that develop on the sea floor. scientists hypothesize that phytoplankton blooms cause these dead zones. phytoplankton blooms occur when excess nutrients are introduced by pollution from fertilizers, sewage plants and the burning of fossil fuels. which of the following would most likely cause an increase in these contributors to dead zones? rainfall patterns that increase freshwater runoff from terrestrial ecosystems replacing coal-fired power plants with windmills farming practices that reduce nitrate and phosphate applications constructing efficient water-recovery and treatment plants

this protocol provides a detailed procedure for nucleoprotein extraction from cultured cells and tissues in an efficient manner.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
