Answer:
Cardiovascular system
Explanation:
Cardiovascular means relating to the heart and blood vessels. Even though blood system sounds like an appropriate name, the circulatory system studies more than just blood, it studies the heat and blood vessels as well.
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: rock melting—>crystallisation
Explanation: I am going to assume that the process must be a formal word like sedimentation, metamorphism, or crystallisation. The formal word for it is crystallisation. Metamorphic rocks are rocks that doesn’t melt even when exposed to extreme heat. This can be found under the Earth’s crust (so basically underground) near/under mountains. It is really hard to melt, but when they do melt (I’m not sure what the formal word is for this process, so I’m going to call it rock melting) the metamorphic rock turns into magma. This magma comes to the surface whenever the volcano erupts and is called lava. Whenever the lava dries up (crystallisation), it forms igneous rocks.
Answer:
I would say that the best answer is A.
Explanation:
Both Bacteria and Archaea, lack a nucleus and are unicellular. Most Archaea have a Cell wall, however there are a few exceptions, all Bacteria have a cell wall. Maybe the biggest difference between the two however, is where they thrive. Archaea live in extreme conditions, while bacteria don't. Due to this, I would say that the best answer is A, because this is the only question with a major difference in answers.
The answer is 2 clast size
