B because that doesn't have anything to do with structure

I believe the answer is B. Structural adaptations are characteristics that change over time. Some animals adjust over the years to live better in their environments, and this is what it was talking about.

Elephants have long trunks to reach leaves they couldn't get to if their trunks were small. Same with the humming bird and the rose bush. They are adapting. However, the dog is only getting a drink. The dog can do that without having to adapt to anything.

Neurons transmit signals to the central nervous system. The brain processes this information to initiate a response. Two neurons communicate with each other through the ( axon , dendrite, synapse) . The ( cerebrospinal cord, glial cell, neurotransmitter) is released at the site to initiate action potential and carry the signal through the body.

synapse

neurotransmitter

Explanation:

Neurons are the basic units for the transmission of signals to the central nervous system. The two neurons are connected through the syanpse. Synapse is the space or junction between two nerve cells, or neurons.

The neuron receives signals through dendrites and two neurons  communicate with each other through a chemical called neurotransmitter, which is released at the end of a nerve fibre and carry the signal through the body.

Hence, the correct answers are synapse and neurotransmitter.

How does nitrogen leave a food chain?
vitfil [10]

Answer: c

Explanation: Plants and animals need nitrogen to make proteins but they cannot take it in from the air. Because nitrogen is unreactive as a gas, it has to be transformed into a new molecule. When bacteria in the soil takes nitrogen from the air, it becomes nitrates. Finally, it can move through the food chain in this form.
