The correct answer is directional selection
Explanation: Natural selection is one of the basic mechanisms of evolution proposed by Darwin and can be classified into three types: <u>directional, stabilizing and disruptive selection.</u>
Directional Selection is one of the simplest forms of natural selection. It selects one of the extreme phenotypes and is responsible for most of the phenotypic changes that occur during the evolutionary process.
Answer:The Cohen's d is 0.37
Explanation: Cohen's d is a difference used to determine the standard differences between two mean.
The Cohen's d formula is
d = (M1 - M2) ÷ Spooled ......(1)
M1 is the mean satisfaction of the first group = 9.1
M2 is the means satisfaction of the second group = 6.8
Spooled is the standard deviation pooled.
STEP1: Find Spooled
In statistics, the square root of variance gives standard deviation.
Therefore;
Standard pooled = √variance pooled
Spooled = √38 = 6.16
STEP2: Find Cohen's d
Using equation one
(9.1 - 6.8) = 2.3
2.3 ÷ 6.16 = 0.37
Therefore the Cohen's d for the research is 0.37

Answer: the correct answer is b. selective optimization with compensation
Explanation:
Selective Optimization With Compensation is a strategy for improving health and wellbeing in elderly and a model for successful aging. It is recommended that seniors select and optimize their best abilities and most intact functions while compensating for declines and losses. For example, an elderly person with diminishing eyesight who loves to sing could focus more time and attention on singing, perhaps by joining a new choir, while cutting back on time spent reading. Overall, this model suggests that seniors take an active approach in their aging process and set goals that are attainable and meaningful.
