Fermentation enables cells to produce chemical energy from the breakdown of sugar
In the large rainfall is some water remains in the top of the soil the rest of this water is seeped into the ground.
<u>Explanation:</u>
- Mainly the absorption of water by the ground depends upon the nature and the fertility of the soil.
- When the ground receives the water it mainly accounts for the absorption and then there will be a runoff. The absorption helps to raise the level of groundwater for future usage.
- The amount of water that can get into the soil mainly depends upon the permeability of the soil surface. The water which can't infiltrate in the soil runs off into the water bodies.
- The water is an essential requirement for survival and the existence of biological organisms.
1. Scientific method is the techniques that scientists used to carry out investigation process. It is made up of five steps, which are:
a. Observation: this is the stage in which a scientist make an observation to which he did not have an explanation.
b. Formation of a research question: in accordance to observation made, the scientist form a question on which his experiment will be based
c. Formation of hypothesis: at this stage the scientist offers a proposed explanation for the observation which he had made and state what he expects at the end of the experiment.
d. Conduction of the experiment: at this stage the scientist carry out the experiment using appropriate means.
e. Analysis of data and drawing of conclusion: this is last stage of the investigation, at this stage, the scientist analysis the results he obtained and draw a conclusion based on the results of the data.
2. Scientists used scientific method to carry out scientific investigations because the method minimize the influence of bias and prejudice in the experiments that they carry out. The method provides an objective, standardized approach to scientific investigation; this result in reproducible results which can be achieved by other scientists in every parts of the world. The method also helps to minimize errors during investigation.
The answer is c because of science
