A student sets up a controlled experiment to test the effect of a fertilizer on plant growth. They use 2 tomato plants, one is given 1 cup of water every day, 1 cup of fertilizer every week and daily sun and constant temperature. The second plant is given ½ cup of water every day, no fertilizer and sun every other day and constant temperature. Using your knowledge of the Scientific method why is this not a good experimental design? A.)The second plant should also be given some fertilizer. B.)The second plant had different controls and so it cannot be compared for just the effect of fertilizer C.)The second plant should have a change in temperature. D.)The second plant should not have that much water every day.

the eggs of the insects should be the first thing collected at the scene.

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.
