Some giraffes have long necks and some have shorter necks. The ones with longer necks can reach food sources like tall trees as
well as eat grasses on the ground. How will this difference MOST LIKELY help the giraffe population? A) Their number will remain unchanged.
B) Over time, more will have longer necks.
C) Giraffes will move from place to place for food.
D) There will be great differences among the giraffe population.
<u>Answer</u>: Over time, more will have longer necks.
<u>Explanation</u> :
Among the two types of giraffes, the ones with longer necks have an advantage of obtaining food from tall trees as well as the grasses on the ground.
Due to this advantage, the tall necked giraffes are much better adapted to survive in case of calamities involving food shortage as they can obtain food from varied source.
Thus, the trait of the long neck will be selected by naturalselection and the population of long neck giraffe will increase.
Flying foxes disperse the Cycad seeds if the seed sometimes get swallowed whole.
Explanation:
Cycads are gymnosperms they do not have seeds enclosed in fruit. Therefore the bats are not attracted to cycad fruit.
If the bats were susceptible to neurotoxin then they must not have been the frequent feeders of cycad seeds. Biomagnification of neurotoxin in flying fox is a widely researched topic.
Beetles do not have an association with these bats thus the bats must not be assisting them as important pollinating agents.
