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
Hello! Your answer is the bottleneck effect.
Speaking more broadly, genetic drift is when a population becomes smaller, and there are fewer genotypes in the gene pool. There are two types of genetic drift: the bottleneck effect and the founder effect.
The bottleneck effect is when an environmental change / human activity causes many members of the population to die, which means that the gene pool is now represented by just a few organisms. This is correct in this scenario, as an environmental change caused the gene pool to be reduced.
The founder effect is when a new colony is established elsewhere, so only alleles in the smaller founder group will be reproduced.
Hope this helps!
I believe the answer is c)
Look at the Stamen since thats the part of the flower that produces pollen
Answer;
-Cochlea; rods and cones; retina
Making an analogy between hearing and vision, the auditory hair cells in the cochlea are similar to the rods and cones in the retina.
Explanation;
-There are two types of photoreceptors in the human retina, rods and cones. Rods are responsible for vision at low light levels (scotopic vision). They do not mediate color vision, and have a low spatial acuity.
-Cones are active at higher light levels (photopic vision), are capable of color vision and are responsible for high spatial acuity. The central fovea is populated exclusively by cones.
The cochlea is a portion of the inner ear that looks like a snail shell. It receives sound in the form of vibrations, which cause the stereocilia to move. The stereocilia then convert these vibrations into nerve impulses which are taken up to the brain to be interpreted.
