Information about the body and its surroundings is provided through the senses. Olfaction (smell), gustation (taste), equilibrium (balance and body posture), vision, and hearing are the five distinctive senses that only humans possess. We also have broad senses, sometimes known as somatosensation, that can react to stimuli including pressure, temperature, pain, and vibration. Somatosensation includes the sense of limb position used to monitor kinesthesia (limb movement), proprioception (the position of bones, joints, and muscles), and vestibular sensory, which is an organism's sense of spatial direction and balance. Although the sensory systems connected to these senses vary greatly, they all have the same purpose: to cause the nervous system to produce an electrical signal in response to a stimulus, such as light, sound, or body position.

<h3>What is Action potential ?</h3>

When a neuron transfers information away from the cell body and down an axon, it experiences an action potential. The action potential is also referred to as a "spike" or a "impulse" by neuroscientists. A depolarizing current causes an explosion of electrical activity known as the action potential.

Different ions crossing the neuron membrane result in action potentials. The sodium channels first open in response to a stimulus. Because the inside of the neuron is negative compared to the outside and there are much more sodium ions on the inside, sodium ions rush within the cell.

Depolarization, overshoot, and repolarization are the three phases of an action potential.

Giardia exists in two forms--cysts and trophozoites. While both are required for the life cycle of Giardia, only the cyst is con
hram777 [196]

Answer:

Because the trophozoites are unable to survive outside a host.

Explanation:

The term infectious is used for a disease or microorganism that can be transmitted from one organism to the other organism through the environment. If we look at the two forms of Giardia, we find that out of the two forms viz. cysts and trophozoites, only the cysts of Giardia have the ability to remain alive in the environment outside the host and thus they are able to be transmitted to the other organisms. On the other hand trophozoites are not able to survive in outside environment so there is no chance of transmission of trophozoites.

What does it mean for an environment to be isotonic?(1 point)
HACTEHA [7]

A solution to be isotonic refers to b) The concentration of solute in the environment and the concentration inside the cell are at equilibrium.

  • Isotonic solution is the solution that have equal concentration of solute on both sides of the solution separated by a membrane.
  • If a cell is kept in an isotonic solution that means the concentration of the solute inside the cell is the same as that of the outside then the movement of solvent does not occur between the cell and the external environment.
  • The osmotic pressure inside the cell and outside the cell across the semipermeable membrane of the cell becomes the same due to equal concentration of the solute on each side.

0.9% normal saline is an example of isotonic solution.

mojhsa [17]

Answer: Water as a universal solvent

Explanation:

Water is a universal solvent because of its property of dissolving a large number of molecules of different kind.  The water at the biological level forms the major body weight of the organisms. It helps in supporting the cell metabolism and function. It is the main component of the liquid component of blood that is plasma. The water dissolved in it various vitamins, minerals, fibers, and other components of the food and helps in digestion of food in the body. Thus in human and animal body water plays an important role in circulation and digestion process.
