Archaea<span> and </span>bacteria<span> have generally similar </span>cell<span> structure, but </span>cell<span> composition and organization set the </span>archaea<span> apart. Like </span>bacteria<span>, </span>archaea<span> lack interior membranes and organelles. Like </span>bacteria<span>, </span>archaea cell<span> membranes are usually bounded by a </span>cell<span> wall and they swim using one or more flagella.</span>
Answer is labyrinthodont
About 110 million years ago, labyrinthodonts ( maze-toothed), a group of extinct amphibians. They were evolved from lobed-finned fish in the Devonian period. They were dominant animals in the rift valley was present at that time between Antarctica and Australia.
Answer:
True
Explanation:
When we talk about fossils, we are referring to the remains of organisms that had once lived. These are traces of the organisms that existed in the distant past.
These fossil records help us to reconstruct plant and animal life in the past as well as their evolutionary processes, which can be either slow or rapid.
Fossil records reveal extinct species and help us to make sense of the evolutionary processes on earth.
The examples of positive feedback loops are as follows:
- contractions during the process of giving birth
- Blood clotting
<h3>WHAT IS POSITIVE FEEDBACK LOOP:</h3>
- Positive feedback loop is that in which a change in a given direction causes additional change in that same direction.
- The contractions during the process of giving birth is an example of positive feedback loop because the contractions further stretch the walls and continues until birthing occurs.
- Also, the clotting of blood causes the stoppage of blood flow.
Therefore, the examples of positive feedback loops are as follows:
- contractions during the process of giving birth
- Blood clotting
