Answer:
The fittest organism survive and produce.
<span>Only one sperm normally fuses
with an egg because if more than one sperm fuses, through a process
called polyspermy, development of the zygote usually stops.
</span>
<span>Fertilization of one egg by
two sperm is possible, but the resulting zygote is almost never viable
because such a zygote would have three sets of chromosomes instead of
the normal two. This condition, called triploidy, is usually
incompatible with life. Those rare triploid infants that do survive to
term have severe and multiple birth defects and rarely live more than a
few days. </span>

because it benefits the soil. the long alfalfa stand life also gives the soil a chance to rest from frequent field crop rotations, helps provide nitrogen for subsequent crops, and improves soil tilth. this helps prevent pesticide and sediment movement to natural waterways.
good luck :)
hopefully, this helps

Answer:
The adaptation in owl butterfly helps it to camouflage and also protects it from predators. Adaptations allow organisms to be better suited to their environment. So the answer is both 'A' and 'B' .
Explanation:
Owl butterfly use the concept of mimicry. It is a form of <em>adaptation</em> in which they fool the predator in thinking that they are owls and not butterflies. These butterflies have eyespots under their wings. By flashing them they look like the <em>eyes </em>of an owl.
Since owls feed on small animals, and small animals feed on butterflies, the owl butterflies protect themselves from predators. The small animals thinking that the butterfly is an owl, run away instead of coming closer. This way these small insects camouflage and protect themselves.
