Answer: The correct answer is peripheral
Explanation:
The Peripheral nervous system consists of the following:
- sensory neurons, which leads all parts of the body to the central nervous system
- motor neurons that runs the central nervous system to all parts of the body.
Thus, Peripheral nervous system is the answer
Answer:
d. Populations have the potential to grow to very large numbers
Explanation:
Natural selection and artificial selection both cause changes in animals and plants. However, the natural selection happens naturally, but selective breeding (artificial selection) only occurs by humans interventions. Natural selection has four components:
- Variation.
- Inheritance.
- High rate of population growth. In artificial selection, selection itself diminishes the probability of adaptation. But in natural selection populations have more offspring and have more chance to alive in struggling for local resources.
- Differential survival and reproduction.
Answer:
Coelenterates are the first invertebrates to develop a true nervous system.
I think the correct answer from the choices listed above is option A. The first type of cell to differentiate is a neuron. The neurons are cells that process and transmits information through electrical and chemical signals. Hope this answers the question.
