The molecule that does not enter the cell via facilitated diffusion is :
( A ) Fats
<h3>Facilitated diffusion</h3>
Facilitated diffusion is a type of spontaneous transport system ( passive ) in which charged and polar molecules such as carbohydrates, Amino acids, Nucleotides and ions move across a biological membrane. with the aid of a specific transmembrane integral proteins while
Fats ( fatty acid ) enters the enterocyte through simple diffusion process via the plasma membrane.
Hence we can conclude that The molecule that does not enter the cell via facilitated diffusion is Fats.

Science is an organized way of using evidence to learn about the natural world.
The goal of science is to investigate and understand the natural world, to explain events in thenatural world, and to use those explanations to make useful predictions.
The Scientific Method Itself:
I. Observations:
Whether they start with a problem or not, scientists make careful observations.
Observations are a way to collect data (recorded observations or information) about events or processes in a careful, orderly way, using the senses (sight, hearing, touch, taste and smell).
Two types of data include:
a) Quantitative data: Are observations which collect data that can be directly measured or counted.
b) Qualitative data: Are observations involve making careful descriptions or drawings and do not involve numbers.
Inference: A logical interpretation of an observation based on prior knowlege. An educated guess as to what is occurring.
II. Hypothesis:
A proposed scientific explanation for a set of observations. Scientists devise hypotheses based on logical inferences, prior knowledge and informed, creative imagination.
Hypotheses may be tested by controlled experiments, or by collecting additional data.
III. Controlled Experiment:
A way to test a hypothesis by testing a single variable by changing it while keeping all other variables the same.
Variable: Any factor during an experiment that could change and affect the results (Examples: Temperature, pressure, amount of light, color of light, human error, etc......)
Manipulated variable: The factor in an experiment that is deliberately changed to test the hypothesis.
Controlled variable: any factor during an experiment that a scientist purposely keeps the same.
During the experiment, a scientist divides the tests into 2 groups, the control setup and the experimental setup.
Experimental setup: The part of the experiment that contains the manipulated variable.
Control setup: The part of the experiment that does not contain the manipulated variable. It may be called the placebo.
Explanation:
the scientific method is the process that involves various steps to develop knowledge about the natural world that has characterized the development of science
Steps of the scientific method
•ask a question
•do background research
•construct a hypothesis
•Test your hypothesis by doing experiment
• Analyze your data and draw conclusion
•communicate your results
Light dependent reactions require an actual source of light, and this is from the sun, for energy to carry out the first stage of photosynthesis. They need solar energy to split a water molecule in order to obtain electrons from hydrogen to be used in fueling photosynthesis.
Light independent reactions do not require a light source for energy but rather they use energy that was created by the light dependent reactions to complete the process of photosynthesis in which different carbohydrates for the plant are made.
