Answer:
The tiles can be arranged as follows:
- make an observation
- ask questions
- construct a hypothesis
- test the hypothesis
- analyze the results and make conclusions
- communicate the result
Explanation
A scientific investigation begins with certain observations. By seeing these observations, a question is made. To answer the question, a hypothesis is generated. A hypothesis is a tentative statement that can either be stated s correct or wrong. To test the hypothesis, experiments are made and results are deduced from the experiments. Based on these results, a hypothesis can be proved as correct or wrong. These results are then communicated to check for their authenticity.
The Characteristics of life are growth, reproduction, homeostasis, sense and respond to stimuli, obtain and use energy, made of cells, adapt and evolve.
Answer:
The photosynthetic organisms of the water can survive at a depth of 100 meters due to the presence of blue light.
Explanation:
There are two colors which are responsible for the process of photosynthesis. These two colors are red and blue. Red and blue light of solar radiation is absorbed and green light is reflected back by the green pigment called chlorophyll. So in the depth of 100 meters in the water, blue light is present so plants can make their own food during photosynthesis.
