How do cartographers apply to life in Antarctica

Biology
1 answer:
marshall27 [118]3 years ago
5 0
Okay. I think I know the answer, but I could be dramatically wrong. Cartographers are people that design and produce maps. In Antarctica, a cartographer can make maps to help understand location of certain important landmarks and discoveries made in certain areas.

How does the digestive system of poultry vary from other animals?
Vinvika [58]

Answer:

They digest without the use of teeth.

Explanation:

The food trickles from the crop into the bird's stomach (proventriculus or gizzard) where digestive enzymes are added to the mix and physical grinding of the food occurs. The gizzard is why chickens do not need teeth.

In a common reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, where does the sign
kobusy [5.1K]

In a reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron. The answer is motor neurons.

<h3>What is the reflex arc?</h3>

The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.

In general terms,

1) A stimulus of varying nature reaches the body.

2) The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-.

3) The CNS processes the information and sends another signal as a response to the stimulus.

Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.

The neurons involved in the mechanism are:

• Afferent or sensorial neurons

• Interneurons

• Efferent or motor neurons

Mode of Action:

  • <u>Ascending branch</u>

The stimulus reaches the body and is received by the specialized sensory receptors.

Afferent neurons, placed in the dermis and epidermis, receive this information from receptors, react and send it to the central nervous system as nerve impulses.

  • <u>Descending branch</u>

Interneurons in the CNS, process the information and send a motor response.  

Efferent neurons carry the response from the CNS to the effector organs, which might be either a muscle or a gland.

Finally, the target tissue responds to the stimulus as a contraction -muscle-,or as hormones release -gland-.

A motor neuron is formed by a cellular body, dendrites (cytoplasmic extensions that receive stimuli from other cells), and a long axon that is capable of conducting the electrochemical signals.

The axon brunches out into several extensions when it approaches the muscle.

At the end of each brunch, the axon is inserted in the muscle fiber surface, composing neuromuscular join.

This is the last part of the NS involved in the process before the muscle contracts.

After a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron, and from there to the effector.  

The corrct answer is motorneuron.
