Water boils at 212 degrees farenhiet
Answer:
C.
Explanation:
Absolute dating is defined as the method used to determine the age of biotic or abiotic things on a specified chronology in geology and archaeology.
Layers of the soil are used to determine the age of a geologic event is not a form of absolute dating because the deepest river deposits in the specific basin is used to determine the geological event.
So, the deposits of soil are used to tell the the age of a geologic event and not the layers of soil.
Hence, the correct option is C.
Biologist
study life to the extent to which they can uncover, unearth and investigate unseen,
latent and concealed life forms that are still many in number, these crawling
and under the water creatures. And in experimental sense, many biologists are
guided by the ethics in researching life forms. This is to protect and inhibit
other biologist in killing thousands of these living organisms and prevent them
from becoming extinct. Remember that biologists or any other scientists study
because of knowledge and to contribute to the scientific world of making the
ecosystem including us into a much better and cultured place and not the
opposite.
Hence, there are non-experimental and experimental approaches which
are all subject to ethics. In exploring life forms, it is quite unlimited but
studying life forms in experimental sense, it is somehow depends on the number
of species that the biologists’ study.
The correct answer is B. Ordovician period
Explanation:
Plants are mainly multicellular organism that depends mainly on photosynthesis to obtain energy, this includes a wide variety of species such as grass, flowering plants, trees, shrubs, etc. Additionally, plants are considered as one f the two major divisions or kingdoms along with animals. In terms of history, it has been determined first land plants appear during the mid-Ordovician period around 470 million ago, although organisms that were the origin of land plants developed in water in previous periods, also by the Devonian period a wide variety of plants have emerged with features that are still part of plants nowadays. Therefore, plant life first appeared on land during the Ordovician period.
