The European green crab is an invasive species that has recently entered inland waters of Washington Once established, this crab can disrupt the natural ecosystem by outcompeting native species for food and habitat. A biologist is collecting data from local salt marshes and estuaries to evaluate the impact of the invasive crab on the populations of native organisms that live there. Which
experimental design will most efficiently provide accurate, reliable data for evidence?

climate change and pollution

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.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds

my answer is the prothallium.brainliest
