Answer:
C
Explanation:
According to the trend line graph the temperature is 20°C after 45 minutes
Answer:
I agree with her.
Explanation:
ATP definitely is the most widely used high energy molecule - especially for cells. But, it is not absolutely necessary for some "passive" cellular mechanics. We can look at passive diffusion of cellular processes which may include; passive diffusion of water, or sugar molecular across a cellular membrane.
1)
To feel an impulse, the receptor must be sent a signal to the brain where it could be interpreted. The signal should be caught by the receptor, send into the spinal cord, then arrives at the brain.
1. Object touch the heel
2. impulses generated in the receptor cells
3. impulses transmitted through a sensory neuron
4. impulses transmitted through neurons in the spinal cord
5. impulses reach the brain
6. brain process the impulses
7. you feel the object touching your heel
2)
Nerves
Spinal cord
Brain
The nervous system is made of central nervous system and peripheral nervous system. The peripheral nervous system is made of the network of nerves. The central nervous system is the brain and spinal cord that will receive impulse and send a response afterward. While brain could send the various signal, spinal cord could only send responses for reflexes.
3)
a. the diagram is showing Neuron cell
The nervous system is made up of multiple neuron cells. The neuron cells are specialized in sending a signal. It has a long axon that could deliver the signal far away. The signal is only one way though, so you will need a different neuron for receiving receptor signal and sending a response signal.
b. Two missing labels in the picture would be: axon.
It seems both of the label pointing out to the axon of the nerve cell. Since both of it pointing the same neuron cell, it should have the same name. Axon has a role in delivering nutrient and signal across the body.
c. Myelin sheath will allow the signal to run faster. This will help in a process that needs speed like reflexes. The sheath will cover a part of the neuron and prevent the ion exchange. Myelin sheath stop in some part called node of Ranvier. This will allow the action potential to "leap" from node to node, make it travel much faster.
Answer:
D
Explanation:
With larger storage, a larger area in the cell is taken up. The other answers are irrelevant to the question.
Im pretty sure it is C because all living things consist of at least one or more cells
