Answer:
HYDRA
Explanation:
The nerve cells are scattered in each layer of the body wall and these neurons send information from sensory organs. Based on the given choices above, the organism that has a nerve net that allows it to respond to a stimulus in a coordinated way is the HYDRA.
The seven major plates<span> are the African </span>plate<span>, Antarctic </span>plate<span>, Eurasian </span>plate<span>, Indo-Australian </span>plate<span>, North American </span>plate<span>, Pacific </span>plate<span>and South American </span><span>plate</span>
I believe this would be the cerebellum. This part of the brain is used for motor control like moving the fingers say and cognitive functions (to do with thinking) and also can affect the feelings of pain and pleasure.

In the study of Gigord and colleagues using Elderflower orchids, the allele frequencies of yellow and purple flowers varied such that when the yellow allele started to become rare, the reproductive success of purple flowers decreased and the reproductive success of yellow-flowered individuals increased in a process known as <u>frequency-dependent selection.</u>

Frequency-dependent selection is an evolutionary process in which the fitness of a phenotype or genotype is dependent on the frequency of that phenotype or genotype in a particular population.
- Positive frequency-dependent selection raises the fitness of a phenotype or genotype as it becomes more prevalent.
- In the case of negative frequency-dependent selection, the fitness of an increasingly prevalent phenotype or genotype diminishes.
In a broader sense, frequency-dependent selection involves biological interactions that make the fitness of an individual dependent on the frequencies of other genotypes or phenotypes within the population.
