9) Identify the FALSE statement regarding sensory receptor cells. A) A graded potential is referred to as a receptor potential.
rjkz [21]

Answer:

<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>

<u></u>

Explanation:

Neurons,  specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.

Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:

  • photoreceptors
  • mechanoreceptors
  • chemoreceptors
  • thermoreceptors

Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.

A scientist discovers that a soil bacterium he has been studying produces an antimicrobial that kills Gram negative bacteria. Sh
nexus9112 [7]

The question is incomplete as it does not have the options which are:

resistant

semisynthetic

synthetic

natural

Answer:

Semisynthetic

Explanation:

Antibiotics are the microbial compounds which are obtained from the micro-organisms which are found effective against the bacteria as they act by inhibiting the activity of the bacteria which ultimately kills the bacteria.

These antibiotics can also be distinguished based on their synthesis: natural, semi-synthetic and synthetic antibiotics.

The semi-synthetic antibiotics are the antibiotics which are obtained from the microbes but are modified artificially by making chemical changes to increase the effectiveness of the antibiotic and making the antibiotic as broad-spectrum bacteria.

Since the properties of the antibiotics provided in the question are similar to the semi-synthetic antibiotics, therefore, is considered semi-synthetic bacteria.

Thus, Semisynthetic  is correct.

A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypoton
Tcecarenko [31]

Answer:

True

Explanation:

This process is called Chemiosmotic Theory.

Two different solutions with a semi-permeable barrier (it allows to pass throw just water or solute, not both) will try to get into equilibrium.

Then, if you allows to pass just water though the barrier, it will go from the solution with less solute to the solution with more solute, in order to reach the solution equilibrium.

ch. 4 After inhalation into the lungs, oxygen gas is more concentrated in the _____ and diffuses into the _____.
sertanlavr [38]

From what we know, we can confirm that after inhalation into the lungs, oxygen gas is more concentrated in the alveoli and diffuses into the blood.

<h3>Why does this happen?</h3>

The alveoli are the primary place for the interchanging of gases to take place. This means that oxygen enters the lungs and makes its way into the alveoli, where it diffuses into the bloodstream in exchange for <u>carbon dioxide </u>that is later expelled from the body during <u>exhalation</u>.

Therefore, we can confirm that after inhalation into the lungs, oxygen gas is more concentrated in the alveoli and diffuses into the blood.
