Plants participate in both short- and long-distance signaling. Explain how nerve cells show these two functions, as well. (3 poi

nts)
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).


Nerve cells release hormones into the synapses between them (short distance). These hormones can also transverse the bloodstream (long distance).


Nerve cells release neurotransmitters into gap junctions between them (short distance). They also use electrochemical gradients that can travel the length of each cell quickly, along a network of cells (long distance).


Nerve cells use plasmodesmata to communicate between them individually (short distance). They also use ion-gated channels to create an electrochemical signal that can be propagated over long distances in their network (long distance).

Answer:

Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).

Explanation:

Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.

The perirhinal cortex is particularly important in ________ and receives more input from ________ than from ___________
dedylja [7]
The perirhinal cortex is particularly important in visual recognition and receives more input from the occipital lobe than from other cortical areas. In addition, the perirhinal cortex is a cortical region in the medial temporal lobe that is made up of Brodmann areas 35 and 36. It obtains highly administered sensory information from all sensory regions and is usually accepted to be a significant region for memory.

A population of kangaroos is growing at a rate of 2% per year, compounded continuously. If the growth rate continues, how many y
antoniya [11.8K]

Answer:

The correct answer is 20 years.

Explanation:

It is given that the growing rate is 2% or 2/100 = 0.02

This rate got increased to 150%

The formula for exponential growth is:  

A = Pe^rt

Let the initial population be 100%

150 = 100.e^0.02*t

3/2 = e^0.02t

1.5 = e^0.02t

After taking log from both the sides:  

ln(1.5) = 0.02t * ln(e) [ln(e) = 1]

ln(1.5) = 0.02t

t = ln(1.5)/0.02

t = 20.27

Thus, it will take around 20 years for the size of the population to reach 150 percent of its present size on the basis of the exponential growth function.

How does the changing pH affect animals that live in the ocean?
Nesterboy [21]

Answer

The ability of some fish, like clownfish, to detect predators is decreased in more acidic waters. A sudden drop in pH can as cause medical issues, such as comas and seizures in oceanic life. Fish's skeletons are also sensitive to acidity, so their development may be impacted as well.

2.265 kg is the weight for a small bag of sugar. You are baking cupcakes for a school fund drive. It takes 100 g of sugar to mak
katovenus [111]

The total batches of cupcakes that you make with one small bag of sugar will be 22 batches

From the question, we are given the following

Weight of a small bag of sugar = 2.265kg = 2265grams

Since 100g of sugar to make one batch of cupcakes, then:

100g = 1 batch ... 1

In order to get the number of batches of cupcakes can you make with one small bag of sugar, we can write:

2265g =  x ... 2

Divide both expressions;

100/2265 = 1/x

100x = 2265

x = 2265/100

x = 22.65 batches

Hence the batches of cupcakes that you make with one small bag of sugar will be 22 batches
