The answer is D. An anion is a negatively charged ion, which means it has accepted an extra electron (s) from a donor ion (cation). To add an electron, energy has to be released so that the electron can be less excited and go back to its orbital level. The released energy is equivalent to the energy required to remove the electron from its orbital level.
When a stimulus is being detected, this stimulus is being sent to the brain through the sensory neuron, going to the spinal cord then to the brain. The brain then interprets these stimuli, and responds to it using the motor neurons. These are the neurons that are responsible in our actions depending on the stimuli we are exposed to. Hope this helps.
Answer:
Ferns
Explanation:
Ferns -
- These the species of plant , that are found in the shady and rainy areas .
- These classification of plant have a separate gametophyte, and sporophyte generations , where , the sporophyte is dominant .
- No seed plants .
Hence , the correct answer according to the information given in the question is , Ferns .
The correct answers are evolution, genetic mutation and selection.
The early ancestors of horses showed the pressence of digits and now the modern horses have hooves in their limbs. There could be many reasons for the pressence of hooves horses.
These could be due to the genetic mutations, which could have changed the shape of the digits in the limb. Sudden change in DNA can cause mutation and this mutation can change the phenotype of the horse.
There are chances that evolution took place over a period of time that changed the character in the horse.
Natural selection can also be one of the reason for the change in the phenotype of the digits on the limb of the horses.
You would the find the greatest diversity of species in a temperate kelp forest.
I hope this helps.
