Answer:
A) Devonian
Explanation:
Fourth division of the Paleozoic era, the Devonian (or Devonian) comprises the period between 416 and 354 million years ago, succeeding the Silurian and preceding the Carboniferous.
Although in this period the terrestrial environment is increasingly conducive to life, the Devonian is still known as the "age of fish". During this period, the first vertebrae, sharks, lobed-fin fish, ray-finned fish and placodermos (group of fish with armor that took the top of the food chain) emerged. Some freshwater fish developed lungs, which gave them the ability to breathe out of the water - soon the first amphibians would originate from fish with lobed fins. On the continents, however, animal life was still marked by the presence of arthropods, such as arachnids and insects.
Answer:
Path: Atmosphere -> Ocean -> Shells -> Limestone -> Cement Plant
Answer:
The correct answer is: <em>Zonosemata flies with housefly wings are attacked less frequently</em>
Explanation:
The Zonosemata experiment is a scientific experiment that was conducted to investigate how zonosemata flies are able to protect themselves from predation by jumping spiders. In this study, housefly wings were transplanted onto zonosemata flies. This made zonosemata flies protected from attack by jumping spiders. On the other hand, when zonosemata wings were transplanted onto houseflies, they were easy targets for jumping spiders. Therefore, if the sub-hypothesis that wing waving alone reduces predation by jumping spiders is proven, the logical result would be that: Zonosemata flies with housefly wings are attacked less frequently.
Louis Pasteur’s experiments has taken a leap on cell biology. He was able to contribute to the concept of cell theory which suggests that cells came from pre-existing cells, cells are the fundamental unit of life and that all life have cells.
Highlighting on pre-existing cells, early before the experiments of Pasteur, there was the theory of spontaneous generation. This theory claims that organisms came from nonliving objects which is now, truly misleading and wrong.
Answer:
I'm pretty sure the answer is the white pulp
Explanation:
The white pulp (WP) is the primary immunologic region of the spleen in both species; however, the WP makes up less than a quarter of splenic tissue. The red pulp (RP) makes up the majority of the tissue and has an immune function distinct from that of the WP.
