Answer:
Water expands when it freezes making it less dense than the water from which it freezes. In fact, its volume is a little over 9% greater (or density ca.
This must be a riddle, I’m a genius when it come to riddles. It’s time.
There are choices for this question namely:
1 Cesarean section
2 Vaginal delivery with forceps extraction
3 Vaginal delivery with vacuum extraction
4 <span>Fetal scalp electrode
</span>
The correct answer is "cesarean section". In cesarean section, we are preventing the vertical transfer of the virus from the mother to the baby by bypassing the vaginal mucosa (which has secretions, potentially with high viral load). Fetal scalp electrode, on the other hand, is not a method of delivery.
Answer:
This question is incomplete, it is asking to identify the following variables in the question:
Independent Variable: DIFFERENT AMOUNTS OF OIL
Dependent Variables: NUMBER OF KERNELS THAT POPPED
Controlled Variables: TIME FOR POPPING, SAME BRAND OF KERNEL, SAME COOKING TIME
Explanation:
The independent variable of an experiment refers to the variable that the experimenter intentionally manipulates or changes for the purpose of effecting a measurable response in another variable (dependent variable). In this experiment, the independent variable is DIFFERENT AMOUNTS OF OIL used because this is what Jason changes in the experiment.
Contrarily, the dependent variable is the variable that the experimenter measures in response to the independent variable. In this experiment, Jason measures the NUMBER OF KERNELS THAT POPPED from using different amounts of oil. Hence, the NUMBER OF KERNELS THAT POPPED is the dependent variable.
Controlled variables or constants are those variables that must be kept constant or unchanged throughout the experiment in order not to influence the findings of the experiment. In this case, the following variables were kept constant for all the groups: TIME FOR POPPING , SAME BRAND OF KERNEL (Pop rite), SAME COOKING TIME (4 mins).
