The answer is B, it is the only answer that talks about electric signals.
I found the exercise on the internet and bellow are the options:
"A. Seed cones contain ovules.
B. Germinated seeds are haploid.
C. A pollen tube is used to prevent the fertilization process.
<span>D. Pollen grains undergo meiosis to form egg cells."
The correct answer is D.
There are no seed cones, but pollen cones, where the ovules can be found. Germinated seeds are diploid, not haploid. The pollen tube role is to promote the fertilization process by leading the sperm to the egg, once the sperm in this type of plants do not have flagella and therefore no movement.
The correct answer is D because pollen grains are really the diploid germinative cells that </span><span>produce sperm cells.</span>
The change in position from beginning to end and the direction taken is referred to as displacement.
<h3>What is Distance?</h3>
This used to measure how far or close objects are in relation to one another.
Displacement on the other hand has the direction being taken into consideration which is the major difference.

Adaptation
Adaption is the biological process by nature of fitting an organism to its environment.
The finches on the different islands share the same ancestral population that migrated to the Galapagos Islands. However, due to the different environmental conditions on the different islands, the population adapted variably to enable them survive on their respective islands.
Explanation:
Adaptation occurs by natural selection pressures on a population. The individuals with desired traits are more likely to reach maturity and pass down their genes the next generation (due to competition for resources). Therefore, over generation, there will be more and more individuals with these desired traits and fewer and fewer with undesirable traits. The population, therefore, evolves with time. In the case of the Finches this is called divergent evolution/radiation.

I am not 100% sure but I believe that because of increased manufacturing, the air got very polluted and this made many trees darker, like birch. So moths are usually lighter in color so many couldn’t really hide among trees and they were eaten. After some time, many moths mutated and also became darker to blend in when they were on trees to prevent being eaten by predators. In conclusion, the population decreased.
Was this the answer you were looking for?
