Answer:
<u>State</u> anxiety is the actual experience of apprehension and uncontrolled arousal and <u>trait</u> anxiety is a personality characteristic, which represents a latent disposition to perceive situations as threatening.
Explanation:
<u>State anxiety:</u> It is basically a "right now" feeling which changes from moment to moment, manifesting itself as an interruption of an individual's emotion state, leading to a sudden superversion of emotional equilibrium, caused by external factors of current state. e.g An atheletes emotional state at any given time that is variable from situation to situation.
<u>Trait anxiety:</u> It is a personality disposition which is stable over time. e.g An atheletes disposition to interpreting a situation as threatning and responding with an increase in state anxiety.
The answer is stabilizing selection.
<span>Sickle-cell anemia is a recessive disorder caused by the presence of two recessive alleles "s", so genotype is "ss". This disorder is characterized by sickle hemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle hemoglobin. But pathogen that causes malaria affect only normal hemoglobin, so heterozygous individuals will have half of the hemoglobin resistant to the pathogen and those individuals are resistant to malaria.</span>
Stabilizing selection favors heterozygotes Ss, disruptive selection favors dominant (SS) and recessive (ss) homozygotes, while directional selection favors dominant (SS) or recessive (ss) homozygote. Since in this example, people with genotype Ss (heterozygotes) are in advantage, then this is an example of stabilizing selection.
