In the logistic growth model, as a population approaches the carrying capacity, what happens to its growth rate?
A
becomes exponential
B
doubles
C
increases
D
slows to zero
Answers
In the logistic growth model, as a population approaches the carrying capacity, the growth rate of the population will slow down to zero. Thus, the correct option is D.
What is Logistic growth model?The logistic growth model is a parameter which represents the rate at which the population would grow if it were unencumbered by the environmental degradation. A second parameter, that is K, represents the carrying capacity of the system of species which are being studied.
In logistic growth, a population's per capita growth rate gets smaller and smaller as the population size when it approaches a maximum imposed by the limited resources in the environment, known as the carrying capacity (K). Exponential growth model produces a J-shaped curve, while logistic growth produces an S-shaped curve.
Therefore, the correct option is D.

The original base sequence of DNA is : CAG TTA CCA. If the amino acid sequence that results from translation of this DNA base sequence is: valine-tyrosine-glycine, what mutation occurred in the DNA? Explain
A. An addition mutation occurred
B. A deletion mutation occurred
C. A substitution mutation occurred
D. A mutation did not occur.
Answers
C
I think substitution, because the original translation of the original base sequence is glutamine-leucine-proline. The base sequence for valine-tyrosine-glycine is: GT# TA# GG# . of course the last codon is unclear, but the first two gives us enough to know too much change happened for a simple addition or deletion mutation. The bases were completely switched out, therefore it is a substitution mutation. I attached a codon chart.
A patient in the hospital is undergoing testing. The patient's brain is sending electrical signals to motor neurons, but the muscles are not moving in response. What could be a likely cause for this? Explain your answer using complete sentences.

A big, powerful male gorilla is much more likely than a smaller, weaker
gorilla to become the population's silverback, the pack's leader who mates
far more than the other males of the group. The pack leader will, therefore,
father more offspring, who share half of his genes, and are thus likely to also
grow bigger and stronger like their father. Over time, the genes for bigger
size will increase in frequency in the population, and the population will, as a
result, grow larger on average.
