Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars.

HELP ME PLZ :((( IM SOOOO STUCK

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.

Look at the ocean system below.
mash [69]

Answer:

B. Humans will have less salmon available to eat.

Explanation:

First off, you always want to be wary of choices that are kinda extreme. Take for example, choice A., which says All of the oxygen in the atmosphere will disappear. The problem doesn't say that the plankton population will go extinct, just decrease, so oxygen from the atmosphere won't completely disappear. There are also other sources of oxygen. Moving on, C. says that the shrimp will completely disappear from the sea. This is wrong because once again, plankton won't go extinct in the problem. The shrimp population will decrease but not go extinct. Next, D. Choice D is baloney because a decrease in plankton means less food for salmon, which means the salmon would die in the area. That leaves Choice B. Choice B. makes sense because of something called the bottom-up model, which states that an increase or decrease in the amount of organisms in a lower trophic level will affect the organisms in the above trophic levels. We can see that in action here; if the amount of plankton drop, the amount of shrimp salmon will drop, which means less salmon for humans.

Describe (in complete sentences) and give at least 3 examples of pioneer species. *
Sphinxa [80]

Answer:

Plankons, fungi, bacteria, lichens etc. are the pioneer species of ecological succession. Pioneer species are hardy species which are the first to colonize previously biodiverse steady-state ecosystems. Some lichens grow on rocks without soil, so may be among the first form of life the example includes bacteria, fungi, and lichens.
