Concept explainers
Introduction:
Scientists gather information from various experiments. This informationis called data. Most scientists use metric system when they collect data and perform experiments. The metric system uses powers of ten as units with divisions. The general Conference of Weights and Measures established the unit standards of the metric system in 1960. This system was called International System of Units, commonly called SI.

Answer to Problem 9STP
Correct answer :
The correct answer is option C. kilogram
Explanation of Solution
Explanation/justification for the correct answer:
OptionC. kilogram− Kilogram is the S.I unit of mass. Hence, this is the correct option.
Explanation for incorrect answer:
Option A. candela − Candela is the S.I unit of intensity of light and not mass. Hence, this is not the correct option.
Option B. kelvin- Kelvin is the S.I unit of temperature and not mass. Hence, this is not the correct option.
Option D. meter- Meter is the S.I unit of length and not mass. Hence, this is not the correct option.

(mark all that apply) A. A myosin I motor B. A dynein motor C. A myosin VI motor D. A kinesin motorarrow_forwardYou isolate the plasma membrane of cells and find that . . . A. it contains regions with different lipid compositions B. it has different lipid types on the outer and cytosolic leaflets of the membrane C. neither are possible D. A and B both occurarrow_forwardYou are studying the mobility of a transmembrane protein that contains extracellular domains, one transmembrane domain, and a large cytosolic domain. Under normal conditions, this protein is confined to a particular region of the membrane due to the cortical actin cytoskeletal network. Which of the following changes is most likely to increase mobility of this protein beyond the normal restricted region of the membrane? A. Increased temperature B. Protease cleavage of the extracellular domain of the protein C. Binding to a free-floating extracellular ligand, such as a hormone D. Protease cleavage of the cytosolic domain of the protein E. Aggregation of the protein with other transmembrane proteinsarrow_forward
- Topic: Benthic invertebrates as an indicator species for climate change, mapping changes in ecosystems (Historical Analysis & GIS) What objects or events has the team chosen to analyze? How does your team wish to delineate the domain or scale in which these objects or events operate? How does that limited domain facilitate a more feasible research project? What is your understanding of their relationships to other objects and events? Are you excluding other things from consideration which may influence the phenomena you seek to understand? Examples of such exclusions might include certain air-born pollutants; a general class of water bodies near Ottawa, or measurements recorded at other months of the year; interview participants from other organizations that are involved in the development of your central topic or issue. In what ways do your research questions follow as the most appropriate and/or most practical questions (given the circumstances) to pursue to better understand…arrow_forwardThe Esp gene encodes a protein that alters the structure of the insulin receptor on osteoblasts and interferes with the binding of insulin to the receptor. A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant). The researcher then exposed the mutant strain and a normal strain that expresses Esp to glucose and compared the levels of insulin in the blood near the osteoblasts (Figure 2). Which of the following claims is most consistent with the data shown in Figure 2 ? A Esp expression is necessary to prevent the overproduction of insulin. B Esp protein does not regulate blood-sarrow_forwardPredict the per capita rate of change (r) for a population of ruil trees in the presence of the novel symbiont when the soil moisture is 29%.
