Answer:

The variability in marine salinity between habitats will have an impact on the fish living there as the change in the salt level can affect fish life cycle. It depends on the salt tolerance levels of fish. Fishes which adapt to the change   salt conditions will survive.

What are polygenic traits controlled by
STALIN [3.7K]

Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of other animals

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.

What is the pattern in the structures between cytosine and guanine and adenine and thymine.
Scilla [17]
I am not quite sure what you are asking, but I hope this helps! Cytosine, Guanine, Adenine, and Thymine are nitrogenous bases in DNA. Cytosine and Guanine pair up together, and Adenine and Thymine pair up. Adenine and Guanine are purines and Thymine and Cytosine are pyrimidines.
