Answer: Name the predominant fatty acid in each of the vegetable oil are given below:
1) The predominant fatty acid in groundnut oil is oleic acid. Its percentage in the groundnut oil is 46.8% on weight basis.
2)The predominant fatty acid in coconut oil is lauric acid acid. Its percentage in the coconut oil is 47 - 49% on weight basis.
3)The predominant fatty acid in palm oil is palmitic acid. Its percentage in the palm oil is 44% on weight basis.
Answer:
This question is asking to identify the variable in the experimental statement.
The eye chart is the CONTROL VARIABLE
Explanation:
An experiment consists of several variables to look out for in order to achieve any significant result. These variables are independent variables, dependent variables and control variables. Although independent and dependent variables are the major experimental variables, but control variables are also important.
A control variable is the variable that remains constant or unchanged throughout the experiment. Any change to the control variable will affect the dependent and independent variables. In this question, the eye chart is the CONTROL VARIABLE because it remains constant or unchanged. The same eye chart is used for the experiment.
N.B: The distance to the eye chart is the independent variable while the number of letters visible on the line is the dependent variable. Hence, changing the eye chart (control variable) will affect the distance and the number of letters visible.
Answer:
A. Uniformitarianism
Explanation:
The principle of Uniformitarianism was proposed by a Scottish Geologist, James Hutton.
The principle is simply stated as "the present is the key to the past".
The processes that have occurred in geologic past is still in play today. By looking at rock sequences in our present day, we can actually have a firm grasp of the processes they have undergone in the past.
