Can someone me with this?

connor & miguel want to investigate if the type of fertilizer changes the color of their hydrangea flowers. they select 10 hydrangea bushes & plant them in the same yard with the same type of soil. every bush gets 3 cups of fertilizer, but each receiving a different brand. one bush gets no fertilizer. all bushes receive morning sunlight and no afternoon sunlight. all bushes are watered the same amount every other morning. after 4 weeks, the boys observe the color of the blooms on each bush.

1. independent variable:

2. dependent variable:

3. hypothesis:

4. control group:

5. experimental group:

6. constants:

1. Independent variable: type of fertilizer

2. Dependent variable: color of hydrangea flowers

3. Hypothesis:  The type of fertilizer changes the color of their hydrangea flowers.

4. Control group: One bush gets no fertilizer.

This bush is their basis of comparison on what changes the type of fertilizer have on different bushes.

5. Experimental group: 9 bushes where every bush gets 3 cups of fertilizer, but each receiving a different brand.

Since there are 10 hydrangea bushes and 1 of these is the control group, the rest are experimental groups.

6. Constants: - Variables that are the same all throughout the experiment.

* Planted in the same yard with the same type of soil.

* All bushes receive morning sunlight and no afternoon sunlight

* All bushes are watered the same amount every other morning.

what's the

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
