Answer:
The ecosystem with the greatest biodiversity is the one that has the greatest:
A : variety of living things
B :average annual rainfall
C :cover of land area
D :elevation above sea level
Answer is A : variety of living things
Explanation:
Biodiversity, also known as biological diversity is a term used to describe the variety of life on earth across different levels of biological groups. Some scientists have come up with some studies to show that there are over 10,000 species of birds, 200,000 species of flowering plants and almost one million species of insects in the world.
Any environment that is said to have attained the highest level of biological diversity is one that has the most variety of these species of birds, flowering plants and insects.
Answer: Neurons vary in size, shape, and structure depending on their role and location. However, nearly all neurons have three essential parts: a cell body, an axon, and dendrites.
This is false. Memories do not result in the formation of new memories, but the formation of new synapses and connections between the neurons of the nervous system. In order for a long-term memory to be formed, structural changes in the synapses between the neurons have to be accomplished.
