Answer:
C. Paleozoic
Explanation:
Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.
We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.
Answer:
The benefits to use tissue culture to study medication used for treating cancer cells is to observe to details effects of that medicine invitro.
Explanation:
There are various medicines develop by medical science, maximum of them are highly toxic to both normal cell and cancer cell.The most important think to be kept in mind during studying the effects of medications or drug used to treat cancer is that normal body cells should not be affected by that drug.
To avoid this risk the effect of medication or drugs on cancer cell is studied by using tissue culture technique because if the drug adversely effect the normal cells of the tissue culture system,the cell will die but new cell can be regenerated by using hematopoietic stem cells which is not possible invivo.
