What modification is necessary for a successful gas exchange, one example?Alveoli modifications:
Moisture-filled walls: Gases dissolve in the moisture, which makes it easier for them to cross the gas exchange surface. Gases can travel through permeable walls. large blood supply, ensuring that blood rich in carbon dioxide is transported to the lungs and blood rich in oxygen is removed from the lungs.
Compare the Australian Fitzroy River turtle's gas exchange system to that of fish.Gills are found in fish, while specialized excretory openings are seen in turtles. These gaseous exchange systems have a huge surface area, a plentiful blood supply, and are ventilated by water movement for a sharp gradient in concentration. The main distinction is where the gas exchange surface is located.

What is an example of an advantageous trait? (1 point)

O Black bears are not always black, but come in various shades including blonde, cinnamon, and brown
A large proportion of Ireland's population has red hair, more than anywhere else in the world.
Answers
Answer:
The correct answer is a) Elephants are being born without tusks, in response to pressures from poaching for ivory.
Explanation:
Individuals with advantageous traits are more likely than others of their species to survive and reproduce. This is why the elephants would be the answer, as opposed to the peacocks. The brightly colored peacock feathers make them more susceptible to predation, which would actually decrease their chance for survival.
An example of an advantageous trait is the Elephants are being born without tusks, in response to pressures from poaching for ivory.
What are adaptive characteristics of animals?All characteristics that suit their possessors to something are generally said to be adaptive and allow living beings to develop a certain harmony with the environment, thus adjusting themselves for their survival in a given place.

Which conditions suggest that a bond will be ionic?
Answers
Answer:
A and C
Explanation:
Ionic bond is between a metal and a nonmetal
The rule is that when the electronegativity difference is greater than 2.0, the bond is considered ionic.
Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.

Explanation:
describe in general terms the intermediate species that led to the modern panda
Answers
Answer:
The intermediate species that led to the modern panda were likely carnivorous mammals that gradually evolved to have a diet that was primarily herbivorous. This evolution likely occurred over a period of millions of years and involved the development of physical adaptations such as enlarged molars and a strong jaw to help with grinding and crushing plant material. The intermediate species may also have evolved to have a more specialized digestive system to better process plant matter, as well as physical features such as a rounder head and short limbs to help with climbing and foraging in trees.
It is not known exactly what the intermediate species looked like or how many there were, but it is likely that they were small, agile mammals that lived in forests and other wooded areas. They may have had some physical similarities to modern pandas, such as a black and white coloration, but they would have differed in other ways, such as in their size, shape, and behavior.
Overall, the intermediate species that led to the modern panda were likely a diverse group of animals that evolved over time to become specialized herbivores with a unique set of physical and behavioral adaptations.
