Procedure: Get two identical loaves or broad. Put them individually in jars containers with cover Label them A
and B. Bread A is to be exposed in sunlight while Bread B is to be placed in a dark area.
Put 0.5 ml of water on each bread daily. Observe them using hand lens. Do it after a day of
application Record your observation

Observation:
Fill the table.
Development of Bread Molds in a bread
bread sample
A
B
Molds development ( color quantity)

Process Questions:
1 Analyze the data by answering the following questions:
1. Compare the molds developed in Bread A with that of Bread B.
a. How does the volume of water dropped into the bread affect the growth of mold?

b. How does the exposure to light affect the growth of mold?

c. What are the variables (Independent, dependent,
controlled variables) present in the experiment?

2. Formulate the conclusion by answering this question

a. How can you verify your conclusion by performing the same activity using another kind of bread?

b. Formulate a recommendation on how to avoid spoilage of bread

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 !

they dont have any evidence
