The following that is a characteristic that could be applied to both living and nonliving things can contain mostly carbon, hydrogen, oxygen, and nitrogen.
Answer:
Fossil evidence shows that vertebrates made the transition from water to land during the <u>DEVONIAN</u> period.
<u>SALAMANDERS</u> are amphibians that most closely resemble early tetrapods in body form with a long tail and 4 limbs of similar length.
A distinctive characteristic of mammals that is not observed in other vertebrates is <u>ENDOTHERMY</u>.
By the end of the <u>CAMBRIAN </u>period, all major animal lineages were present in the seas due to a great adaptive radiation of animals.
The vertebrate lung first appeared in <u>AMPHIBIANS</u>
Explanation:
Vertebrates started to transition from water to land later in the Devonian period. The vertebrates had to adjust to living on land such as withstanding gravity, breathing in air, adjusting senses to living on land than on water, and significant water loss due to the new environment. This was a big step in the realm of evolution because vertebrates were now able to thrive because they are no longer limited to the resources and space of water.
Salamaders are said to have not evolved much and have some characteristics that resemble early tetrapods. Regeneration of limbs is one of the salamanders unique capability which early tetrapods possessed.
Amphibians are ectotherms, which means they get their energy outside their body or their source of heat would be the heat from the environment. Amphibians and reptiles are ectotherms, and mammals are endotherms. Endotherms can generate heat internally.
The Cambrian period marks the Cambrian Explosion. According to fossil records modern organisms evolved rapidly and soon after split into different phyla due to adaptive radiation as a result of the extinction of dinosaurs.
The evolution of lungs is one of the most important changes in vertebrates which allowed early amphibians of water to move to land. It enabled them to breath air.
Answer:
Predator foraging traits include;
- body size (mass or length),
- gape size,
- hunting or foraging mode (for example, ambush or active hunting), and
- feeding mode (for example, chewing or suctorial) .
Prey vulnerability traits include;
- body size (length and mass),
- body shape,
- defense (for example, physical or chemical protection),
- ability to avoid detection (crypsis or camouflage),
- mobility,
- ability to recognize and detect predators, and
- evasive or escape behavior (which can be elicited by physiological trait responses.
But whether or not predators engage with prey, or prey respond to predators in the first place, depends fundamentally on their relative body sizes (or predator gape and prey body shape). Pursuing prey that are too large or cumbersome can be harmful or energetically costly to predators, and pursuing prey that are too small may not be worth the energetic return.
As these populations continue to reproduce over time, the actions of natural selection can also change the species to make them better predators, or more defensive prey. Either way, this adaptation changes the entire predator prey dynamic. If one species cannot then adapt an appropriate defense, they may go extinct.

Hope it helps.
Not sure if you still need this answer but i am pretty sure its the third option.
