Answer:
I don't have the information from the text book but. People might more and more be using clean energy instead of fossil fuel is because fossil fuel is limited. It's a non-renewable, it takes millions of years to form. Also because global warming is making a big impact on our planet, using clean energy instead of fossil fuel can reduce slow green house emission.
Explanation:
Answer:
1. transfer of heat through direct contact
2. caused by current transferring heat in a fluid
3. transfer of thermal energy by electromagnetic waves
Answer:
1. Myelin sheath
2. Nodes of Ranvier
3. Speed up
Explanation:
A neuron is the fundamental unit of the nervous system and structured into the dendrites, the axons and the cell body.
1. The axons of the neuron are covered by a layer composed of the fatty acids and the proteins that is the constituents of the plasma membrane. This layer is known as the myelin sheath. The myelin sheath provides insulation and increases the speed of transmission.
2. Nodes of Ranvier: The myelin sheath around axons does not form continuous but have discontinuous structures due to the gaps in the sheath. These gaps are known as the Nodes of Ranvier.
3. The nodes of Ranvier increase the speed of the electrical impulse transmission through the neuron.
Answer:
Viruses can adapt to their environment, just as living things do
Explanation:
Sorry there's just one that's all I could come up with, however if I had to guess for no.2 I would say that they can reproduce but viruses can only reproduce with a host. Not on their own
