He is a chemical substance released in inflammatory and allergic responses. the histamine h1 receptor on target cells is a g protein-coupled receptor that activates phospholipase c in response to the binding of histamine. which statements are true about the binding of histamine to the histamine h1 receptor? select all that apply. view available hint(s) which statements are true about the binding of histamine to the histamine h1 receptor? select all that apply. histamine diffuses across the plasma membrane to bind to the h1 receptor. histamine binds extracellularly to the h1 receptor. when histamine binds to the h1 receptor, the receptor undergoes a conformation change and binds the inactive g protein. histamine binds intracellularly to the inactive g protein, activating the g protein. once the g protein is active, it binds to the enzyme phospholipase c, activating it. histamine is likely hydrophilic.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

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.
