<span>This is avoidance conditioning. Brenda has been able to successfully link the over-the-counter heartburn medicine to an avoidance of discomfort. By taking the pill, she has received a negative reinforcement due to the removal of the indigestion. The reinforcement will likely lead to Brenda continuing to take the medicine until she habituates to it and does not receive the same benefit(s).</span>

zimovet [89]
I believe if her hypothesis was incorrect the percentage of the large lobsters with large pincers would decrease. The large pincers help the lobsters to quickly catch their pray efficiently. This would mean the survival of the lobsters with large pincers. A wrong hypothesis would mean that the large pincer lobsters would die and decrease in number.

When voltage-gated sodium ion channels are inactivated, the neuron is _________________. in the absolute refractory period below
Ymorist [56]

Answer:

depolarizing

Explanation:

According to my research on studies by different medical professionals, I can say that based on the information provided within the question the neuron is depolarizing. This is what happens when voltage-gated sodium ion channels are inactivated causing an increas in the neuron's membrane conductance for sodium ions.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

A boy threw a small bundle toward his girlfriend on a balcony 10. meters above him. The bundle stopped rising in 1.5 seconds. Ho
Alisiya [41]

Hi!


We know that the boy must have thrown the bundle with some initial velocity 'v', and that the bundle stops after 1.5 seconds at a height 's' with a final velocity 'u' -which would be 0.

Our known values thus are:

Time (t) = 1.5 s

Final velocity (u) = 0 m/s

Gravitational acceleration (g) = -9.8 m/s^(2)

<em>Note: that the acceleration is negative as it is opposing the direction of motion (acting  down on the object, causing deceleration)</em>

We will be using <em>equations of motion for an accelerating object</em> to solve first for initial velocity, in order to find the distance.

<h3>Initial Velocity using     <u>v = u + at</u></h3>

Rearranging the equation, and using the value 'g' as our acceleration, we get,<em> u = v - at</em>

u = 0 - (-9.8)(1.5) = 14.7m/s

<h3>Distance Travelled using   <u>v^2 = u^2 + 2as</u></h3>

Rearranging the equation, we get, <em>s= v^(2) - u^(2) / 2a</em>

s = 0^(2) - 14^(2) / 2(-9.8)                          

<em>Note: the negative sign is not a part of the initial velocity, but a part of the equation </em>

s = - 216.09 / -19.6 = 11.025 m


The distance traveled by the bundle is hence, ~ 11 meters, which is high enough for the girl to catch.


Hope this helps!

Compared with fraternal twins, identical twins are ________ similar in physical appearance. Compared with unrelated look-alike p
zvonat [6]

Answer;

-No more; no more

Compared with fraternal twins, identical twins are no more similar in physical appearance. Compared with unrelated look-alike pairs of individuals, identical twins report no more similar personalities.

Explanation;

-Compared with fraternal twins, identical twins are much more similar in extraversion, neuroticism and temperament.

-Since fraternal twins are 2 separate fertilized eggs, they usually develop two separate amniotic sacs, placentas, and supporting structures. Identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into two.

Which of the following characteristics, structures, or processes is common to both bacteria and viruses? A. Metabolism B. Riboso
Darina [25.2K]

Answer:

C. Genetic material composed of nucleic acid

Explanation:

The information needed by every organism to perform life functions like reproduction, growth etc are held in the genetic material that the organism carries in its genome. Every genetic material of organisms is composed of nucleic acids, which are only two in nature i.e. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). This is a common feature of all organisms including bacteria and viruses that they contain genetic material which must be in form of a nucleic acid.

The viruses do not undergo a cell division, neither do they contain protein synthesis structures called Ribosomes because they do not have the ability to reproduce or perform any living process outside a living host cell. This means that they strictly depend on another organism's transcriptional, translational, replicational ability to survive.
