Natural selection would probably favor different varieties in the different islands. In other words, beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti (due to lack of food resources). Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits.
Hope This Helps!
One disadvantage of having a large surface area to volume ratio is the heat loss. An organism that has larger surface area has high rate heat gain and heat loss. Therefore they need to eat or acquire nutrients faster in order to sustain life.
The correct answer is: A) pontine respiratory centers
The respiratory centre in the pons is responsible for generating and maintaining the rhythm of respiration. Besides this elementary function, it also has the ability to adjust respiration rhythm in c response to physiological changes. Respiratory centre consists of three major respiratory groups of neurons:
• The dorsal respiratory group (DRG)- initiates inspiration (inhalation)
• the ventral respiratory group (VRG)-responsible for exhalation
• Pontine respiratory group- includes the pneumotaxic (controls both the rate and the pattern of breathing) and apneustic centers (promotes inhalation by sending signals to dorsal group).
The correct answer is - C. genus and species.
The final scientific name of an animal represents two things, its genus, and its species.
The first name is the genus of the animal, in this case we have Canus. The second name is the species of the animal, in this case nipponicus.
All living organisms are classified in a same manner: kingdom, phylum, class, order, family, genus, species.
Since the name Canus reminds me a lot of Canis, I will take the wolf as an example:
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Canidae
Genus: Canis
Species: C. Lupus
