Humans and apes have five fingers they can use to grasp objects. Do you think these are analogous or homologous structures
Ann [662]
Human and apes have 5 fingers that are used for grasping objects, so they have the same function, but they also have a common ancestor and are closely related, that means that this is an example of homologous structures. In evolutionary biology, the term homologous structures means that there are organs and skeletal elements of animals and organisms, that by virtue of their similarity, suggest their connection to a common ancestor.

The stimulation of an inadequate number of sodium channels for the generation of a positive sodium channel feedback loop is cons
diamong [38]

Answer:

Sub-threshold

Explanation:

If the stimulus is too small to generate the action potential, it is considered as subthreshold stimulus. Subthreshold stimulus causes the opening of small number of sodium channel i.e. not enough to generate action potential because action potential is generated by complete reversal of membrane polarity. Slight depolarization is caused by subthreshold stimulus by the opening of inadequate number of sodium channel but its magnitude is not enough to reach the threshold voltage. Consequently the action potential is not generated.

The response produced by subthreshold stimulus is called as local response or local depolarization because it could not travel further. The minimum stimulus required to generate the action potential is call as threshold stimulus and stimulus greater than threshold stimulus is called as suprathreshold stimulus. It changes the frequency of generated action potential.

What is “the balance of nature?” Please answer in 1-2 simple sentences Thank You!!
AnnZ [28]

Answer:

The balance of nature is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system

The _____ nervous system conserves energy, while the sympathetic nervous system consumes energy.
Fudgin [204]

The nervous system conserves energy, while the sympathetic nervous system consumes energy.

<h3>What is the nervous system?</h3>

The nervous system is an organ system that coordinates the activities of muscles, monitors organs, constructs and processes data received from the senses and initiates actions.

The nervous system can either be the following;

  • Sympathetic
  • Parasympathetic

The sympathetic nervous system is a part of the autonomic nervous system that raises blood pressure and heart rate, constricts blood vessels, and dilates the pupils when under stress.

On the other hand, the parasympathetic nervous system is one of the divisions of the autonomic nervous system, based between the brain and the spinal cord, that slows the heart and relaxes muscles.

This suggests that the parasympathetic nervous system conserves energy because it slows the heart while the sympathetic nervous system consumes energy.
