Astudent is investigating the question “which increases a person’s breathing rate more after three minutes, lifting five-pound weights or lifting ten-pound weights? ” she designs an experiment to test the question. which statement most likely describes the dependent variable in her experiment? the breathing rate is the dependent variable because it can be affected by varying weights. she cannot measure the dependent variable until she finishes the experiment. the time of exercising is the dependent variable because it can be measured. the five- and ten-pound weights are the dependent variable because they can affect the breathing rate.

we would need to see the picture to answer it

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.
