Assume there is a certain population of fish in a pond whose growth is described by the logistic equation. It is estimated that
eimsori [14]

Answer:

The correct answer is  p1 = 898 and p2 = 1020.

Explanation:

This is a logistic growth problem and will utilize the following formula:  

Pn = P_{n-1} + r (1- \frac{P_{n-1} }{k} ) P_{n-1}

Given ;

r = 1.7

k = 1500

Po = 400

then,

Pn = 400 + 1.7 (1- \frac{400 }{1500} ) 400

= 400 + 1.7 (293)

= 400+ 498

P₁= 898

Similarly,

P₂= P_{2-1} + r (1- \frac{P_{2-1} }{k} ) P_{2-1}

= Pn = 400 + 1.7 (1- \frac{898 }{1500} ) 400

= 1020

Thus, the correct answer is  p1 = 898 and p2 = 1020.

kirill [66]

Disruption of axonal transport would be a good target for his drug.

<h3>What is disruption of axonal transport?</h3>
  • Axonal transport defects are among the early molecular events leading to neurodegeneration in mouse models of amyotrophic lateral sclerosis (ALS).
  • Gene expression profiles indicate that dynactin-1 mRNA is downregulated in degenerating spinal motor neurons of autopsied patients with sporadic ALS.
  • Disruption of axonal transport also underlies the pathogenesis of spinal muscular atrophy and hereditary spastic paraplegias.
  • The neurotoxin β,β′-iminodipropionitrile (IDPN) selectively disrupts slow axonal transport without affecting fast anterograde or retrograde axonal transport.
  • Impairment of slow axonal transport causes a proximal accumulation of neurofilaments.
  • Because neurofilaments regulate axonal diameter, this accumulation leads to a marked swelling of the axon.
  • Acrylamide causes decreased axonal transport, also causing proximal accumulations of neurofilaments and swelling.
