1.
Geobiology studies the interaction between the earth and the
Correct Answer
C. BiospHere
Explanation
Geobiology is the scientific study of how the Earth and its living organisms interact with each other. It focuses on understanding the relationships between the Earth's physical environment and the biosphere, which includes all living organisms. This field of study explores how organisms have evolved and adapted to different environments, as well as how they influence and are influenced by geological processes. Therefore, the correct answer is biosphere, as it encompasses the study of life on Earth and its interactions with the planet.
2.
Earth material include
Correct Answer
B. Soil
Explanation
The given answer, "soil," is correct because soil is a type of earth material. Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that forms the upper layer of the Earth's crust. It is essential for plant growth and provides nutrients and support for plants. Soil is formed through the weathering of rocks and the decomposition of organic matter over time. Therefore, soil is a significant component of the Earth's material composition.
3.
The first laboratory of geobiology opened in
Correct Answer
C. 1965
Explanation
The correct answer is 1965. This suggests that the first laboratory of geobiology opened in 1965.
4.
The Archae domain was published in the year
Correct Answer
A. 1977
Explanation
The correct answer is 1977. This is the year in which the Archae domain was published.
5.
A technique used to characterize the lifestyle of an organism is
Correct Answer
C. Culturing
Explanation
Culturing is a technique used to characterize the lifestyle of an organism. It involves growing the organism in a controlled environment, such as a laboratory, to study its growth patterns, behavior, and interactions with other organisms. By culturing an organism, scientists can observe its growth requirements, reproductive strategies, and response to various environmental conditions. This technique helps in understanding the organism's physiology, ecology, and overall lifestyle.
6.
'The experiment used to determine the function of genes in living organisms is
Correct Answer
B. Mutagenesis
Explanation
Mutagenesis is the correct answer because it is a type of experiment used to determine the function of genes in living organisms. Mutagenesis involves inducing mutations in the genes of an organism and then studying the effects of these mutations on the organism's phenotype. By analyzing the changes in phenotype caused by the mutations, researchers can gain insights into the normal function of the genes and their role in various biological processes. Mapping, biology, and genology are not specific experiments used for determining gene function, making them incorrect choices.
7.
What can be used to track biochemical reactions?
Correct Answer
B. Isotope tracers
Explanation
Isotope tracers can be used to track biochemical reactions because they involve the use of isotopes, which are variants of elements with different numbers of neutrons. By labeling molecules with isotopes, scientists can track their movement and transformation within biological systems. This allows them to study the pathways and rates of biochemical reactions, providing valuable insights into various biological processes.
8.
The study of rocks is
Correct Answer
A. Sedimentology
Explanation
Sedimentology is the study of rocks, specifically the processes involved in their formation, transport, and deposition. It focuses on understanding the characteristics and properties of sedimentary rocks and the environments in which they are formed. This field of study helps geologists interpret Earth's history, reconstruct past environments, and identify valuable resources such as oil and gas. Therefore, sedimentology is the correct answer for the study of rocks.
9.
The study of the earth's ancient magnetic field is
Correct Answer
D. Paleomagnetics
Explanation
Paleomagnetics is the study of the earth's ancient magnetic field. It involves analyzing the magnetic properties of rocks and minerals to understand the behavior and changes in the earth's magnetic field over time. By studying the orientation and intensity of magnetic minerals in rocks, scientists can reconstruct the past movements of tectonic plates, determine the age of rocks, and gain insights into the earth's geological history. This field of study provides valuable information about the earth's past and helps in understanding processes such as plate tectonics and the formation of continents.
10.
The fossil remains of magnetic particles produced by magnetotactic bacteria are
Correct Answer
C. Magnetofossils
Explanation
The correct answer is magnetofossils. Magnetofossils refer to the fossil remains of magnetic particles produced by magnetotactic bacteria. These bacteria have the ability to orient themselves along the Earth's magnetic field, and they produce tiny magnetic crystals within their cells. When these bacteria die and their remains fossilize, the magnetic crystals are preserved as magnetofossils. These magnetofossils can provide valuable information about the Earth's magnetic field and the ancient environments in which these bacteria lived.
