Answer:
1.Observation and description of a phenomenon. The observations are made visually or with the aid of scientific equipment.
2.Formulation of a hypothesis to explain the phenomenon in the form of a causal mechanism or a mathematical relation.
3.Test the hypothesis by analyzing the results of observations or by predicting and observing the existence of new phenomena that follow from the hypothesis. If experiments do not confirm the hypothesis, the hypothesis must be rejected or modified (Go back to Step 2).
4.Establish a theory based on repeated verification of the results.
Explanation:
Photosynthesis takes place
<span>The answer is c, incomplete dominance. The dominate trait of the red petals is their red color. The dominate trait for the white petals is their white color. When their offspring have pink petals, neither parental phenotype trait is dominate over the other. Their colors are equally represented in the pink color of the offspring, which shows incomplete dominance - a case where neither parental phenotype is more visible than the other. The ratio of their colors represented in the offspring is one to one.</span>
Answer: After several days, a large bubble of gas collected in the upside-down beaker contains OXYGEN.
Explanation:
Plants are known to be be autotrophic (producers) through the use of inorganic substance such as water, carbondioxide and light energy from sunlight in a process known as photosynthesis.
An experiment was carried out by Latecia for investigation of the gas production of a water plant. It's therefore expected that OXYGEN gas which is the by-product given off during photosynthesis in green plants would be collected from the upside down beaker as gas bubbles.
