O bottom-up processing
o facial feedback
selective encoding
O justification of effort
o facial feedback
When someone replicates a emotion, they tend to feel it
Nick is smiling even though he does not feel happy and after a short time he feels happier too. This change in mood is due to facial feedback. Therefore, the correct statement is option B.
What is the facial feedback mechanism?Facial feedback is a psychological theory that suggests that the expression on a face of a person can influence their emotions and mood also. Therefore, when a person smiles even when they are not feeling happy, it can trigger positive emotions in the brain that change in mood.
Nick is smiling even though he is not feeling happy. Therefore, this act of smiling can trigger positive emotions in his brain and changes his mood because of the facial feedback mechanism.
However, bottom-up processing is the processing of sensory information from the environment to create a perception, while selective encoding is a process of selectively attending to and encoding certain aspects of a stimulus while ignoring others.
Therefore, Nick is smiling even though he does not feel happy and feels happy after a short time due to facial feedback.

Answer: b. fossil fuels are nonrenewable, so humans will run out of them eventually. burning fossil fuels also contributes to global climate change by releasing carbon dioxide into the atmosphere.
Explanation:
Fossil fuels are limited and we will run out of them eventually. They cannot be replenished in a single human's lifespan. Fossil fuels contribute to the destruction of ecosystems, but not only that. They release carbon dioxide into the atmosphere that warms the Earth. Therefore, anything other than B. would be incorrect.

What best explains the observations?
A. White flowers increase the plant's fitness, so the population is under directional selection.
B.Yellow flowers increase the plant's fitness, so the population is under directional selection.
C.Yellow flowers increase the plant's fitness, so the population is under disruptive selection.
D.White flowers increase the plant's fitness, so the population is under disruptive selection.
Thebest explanation for the observation is that white flowers increase the plant's fitness, so the population is under directional selection.
What is genetic variation?Genetic variation refers to the differences that exists in the genes of organisms of the same species or different species.
The gene for flower color in the plants has two alleles for yellow and white flower color.
Over time, the proportion plants with white-colored flower increased while that of yellow decreased.
