B. natural selection
C. emergent evolution
D. divergent evolution
Answer:
The correct answer is option A, that is, convergent evolution.
Explanation:
The convergent evolution in evolutionary biology refers to the phenomenon in which the organisms that are not closely associated, that is, not monophyletic, autonomously evolve identical characteristics as a consequence of having to amend to ecological niches or identical surroundings.
For example, the evolution of lungs and gills that serves similar functions in distant organisms is an illustration of convergent evolution.
Answer:
A. Convergent evolution
Explanation:
If analogous or structurally different oragns performing similar function.. We call that convergent evolution.
B. Vacuole
C. Chloroplast
D. Nuclues
Answer:
A. Centriole.
Explanation:
The centriole is the thing at each side of a cell that "pulls" chromosomes apart to the other side of the cell. Here is a photo:
Thank you!
Answer:
I think it`s simplify because of plant cell has more parts that animal
Plant cell = 8
Animal cell= 5
koalas that eat only eucalyptus leaves C. would least likely survive in a change of ecosystem.
The koala or koala bear refer to arboreal herbivorous marsupial that are majorly found in Australia. It is the only remaining representative of the family Phascolarctidae and its closest living relatives are the wombats.
They survive in most climate.
Therefore, koalas that eat only eucalyptus leaves C. would least likely survive in a change of ecosystem.

effect.
B. Disruptive selection divides a population into two new species.
C. Selective breeding creates a new species of dog.
D. A mutation spreads rapidly through a small population.
The example of genetic drift is A. The allele frequency of a population changes due to a bottleneck effect.
Genetic drift refers to random fluctuations in the frequency of alleles (variants of a gene) in a population over time. This can occur due to various factors, such as a reduction in population size or migration of individuals between populations.
The bottleneck effect is a type of genetic drift that occurs when a population experiences a sharp reduction in size, which can reduce the genetic diversity of the population. This can result in certain alleles becoming more common or being lost altogether, even if they were not necessarily more advantageous or disadvantageous for survival.
Disruptive selection (option B) and selective breeding (option C) are mechanisms of natural and artificial selection, respectively, and do not necessarily involve random fluctuations in allele frequencies.
Hence, A mutation spreading rapidly through a small population (option D) could be an example of genetic drift if it results in a change in allele frequency, but the fact that it spreads rapidly suggests that it may be under the influence of natural selection instead.
