List one change in bug morphology that you would reasonably expect in bug populations that have been living on golden rain trees
marysya [2.9K]

Answer:

(a) In this case, small bugs are more likely to have relative fitness on the new food source.

(b) A change that will occur in bug morphology is that the female bugs will turn out to be the same size as the male bugs.

(c) In terms of behavior, the bugs will experience less competition towards reproducing early.

(d) Yes, the dispersing bug would have higher fitness as they will be able to easily get access to new resources once the previous one has run out, whereas the bugs with less developed fight muscles will not be able to do so.

Hope that answers the question, have a great day!

(also, please remember to give 'brainliest' if you found this answer helpful :)

A force of 5000n is applied outwardly to each end of a 5. 0-m long rod with a radius of 34. 0 cm and a young's modulus of 125 ×
Vitek1552 [10]

The elongation of the rod is 5.51 \times 10^{-4}m`

<h3>Young Modulus of a substance</h3>

The young modulus of a substance is the<u> ratio of stress to the strain</u> of material.

Modulus = \frac{Stress}{Strain}\\ Modulus =\frac{Fl}{Ae}

where:

  • F is the applied force = 5000N
  • l is the length of the rod = 5.0m
  • A is the cross-sectional area = \pi r^2 = 0.34^2 * 3.14 =0.362984m^2

Required

Extension of the rod "e"

Substitute the given parameters into the formula to have;

e=\frac{Fl}{A \gamma} \\e=\frac{5000 \times 5}{0.362984 \times 125,00,000}\\e=\frac{25000}{45,373,000}\\e=  5.51 \times 10^{-4}m

Hence the elongation of the rod is 5.51 \times 10^{-4}m`
