Place the following statements that describe the 5 steps in an adaptive immune response in the order in which they occur. - Long lived-immune cells allow the second response to a given microbe to be stronger and faster than the first response - Adaptive immune cells are born in the bone marrow, then mature in either the bone marrow or the thymus - Adaptive immune cells use specific receptor proteins to bind to antigens very specifically - Intracellular signaling pathways are initiated, causing the adaptive immune cell to change cell division, gene expression, and protein translation - Adaptive immune cells kill invading microbes, either directly or indirectly

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

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.
