Step 1: Understanding Evolutionary Terms
Homoplasy refers to similarity in traits due to convergent or parallel evolution, or secondary loss of traits, not due to common ancestry.
Step 2: Evaluating the Options
- Homoplasy: Correct, it describes traits that are similar due to independent evolutionary events.
- Homology: Refers to similarity due to common ancestry, not convergent evolution.
- Heteroplasy: Refers to variation in ploidy or organelle content, not relevant to evolutionary similarity.
- Heterogenecy: Not a standard term in evolutionary biology.
Step 3: Conclusion
Homoplasy describes traits that appear similar due to parallel or convergent evolution.
A closed-loop system has the characteristic equation given by: $ s^3 + k s^2 + (k+2) s + 3 = 0 $.
For the system to be stable, the value of $ k $ is:
A digital filter with impulse response $ h[n] = 2^n u[n] $ will have a transfer function with a region of convergence.
