c. Facial expressions coupled with effective responses
Explanation:
Emotions are an important aspect of human life. Research on emotions has produced several discoveries which led to important real world applications.
- an emotion is the result of the arousal as experienced
- universal facial expressions of seven emotions
- anger, contempt, disgust, fear, joy, sadness, and surprise
- when emotions are experienced even a blind person produces the same facial expressions
Hiya,
Not sure how to answer this! Perhaps there is an image of the question or a lab you can attach to your question/comment so I can help you out?
Thanks.
Answer:
the variability in neuroticism is due partly to genetic variability in the population.
Explanation:
In population genetics, heritability (h) is defined as the amount of the phenotypic variation attributable to genetic factors rather than environmental factors.
Mathematically, h is calculated by using the following equation: H2 = Vg/Vp, where Vg is the variation in genotype, while Vp is the variation in phenotype.
An H value close to zero (0) indicates a very low heritability (i.e., the phenotype depends on the environmental differences between individuals), while an H close to one (1) indicates very high heritability (i.e., the phenotype is firstly dependent on genetic factors).
Euthrophication is caused by excess nutrient run off, such as nitrogen or phosphorus. A common chemical that generally cause euthrophication is fertilizers from farm, if there's heavy rainfall or floods, they're easily washed into the rivers and lakes to cause euthrophication.
Euthrophication generally cause a sudden large scale algao bloom, or other plants, and they may cover the whole surface of water. Once these plants die, decomposers such as bacteria decompose them and take in oxygen for respiration, such that animals from the river originally may die due to lack of oxygen.
