If the cell body of a pns neuron survives when an axon is damaged, axon filaments can extend peripherally from the injured site

toward the original target.

Julli [10]3 years ago

The statement above is TRUE.
The peripheral extension of an axon filament from an injured site toward an original target is an example of axonal regeneration. Axon regeneration in the matured mammalian central nervous system is very limited after injury. But axonal regeneration is still possible in some instances such as the one given in this question.

Question 1- Name 2 ways that humans affect land ecosystems.
lora16 [44]
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Also Humans may destroy natural landscapes as they mine resources and urbanize areas. This is detrimental, as it displaces residing species, reducing available habitats and food sources. ... This can negatively effect an ecosystem because the introduced species may outcompete native organisms and displace them.

30% of B-A=18% OF B+A <br>THEN A:B?
dlinn [17]

Answer:

1:4

Explanation:

30%= \frac{30}{100}

18%= \frac{18}{100}

<em>Rewrite the given information:</em>

\frac{30}{100} (B - A) =  \frac{18}{100}(B + A)

<em>Multiply by 100 throughout:</em>

30(B -A)= 18(B+A)

<em>Divide by 6 throughout,</em>

5(B -A)= 3(B +A)

<em>Expand</em>

5B -5A= 3B +3A

<em>Bring</em><em> </em><em>A</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em> </em><em>and</em><em> </em><em>B</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>another</em><em>:</em>

5B -3B= 5A +3A

<em>Simplify</em>

2B= 8A

<em>Divide by 2 throughout:</em>

B= 4A

Now, we have to find the ratio of A to B.

B= 4A

<em>Divide by 4 throughout:</em>

A = =  \frac{1}{4} B

<em>Divide by B on both sides:</em>

\frac{A}{B}  =  \frac{1}{4}

Thus, A:B= 1:4
