In a biology experiment, the number of cells in a sample was counted. There were 50 cells at the beginning. After 3 hours, 20% of the cells died. How many cells are left? A. 30 B. 40 C. 45 D. 50 相关知识点: 试题来源: 解析 B。解析:开始有50个细胞,20%的细胞死亡,死亡的细胞...
they can both translate from an approximate sense of the number of items in a brief visual display to a discrete number word estimate (i.e., ANS-to-Word), and can generate an approximation, for example by rapidly tapping, when provided with an exact verbal number (i.e., Word-to-ANS)...

of the pen to wiggle up and down. With a typical pen, these constant changes in motion are relatively easy to accomplish. Now conduct the same experiment, with the same pen, however, hold the pen at one of the ends. The pen resists the changes in motion much greater under the second ...
In morphologically richer languages, including French, one must learn the specific properties of number agreement in order to understand the language, and this learning process continues into adolescence. This study examined similarities and differences

of topological materials, the nonlinear Chern number is expected to open up the research stream of nonlinear topological materials including their systematic classification. From the experiment point of view, one can realize nonlinear Chern insulators with theU(1)-gauge symmetry in, for example, ...
NGSEP is an integrated framework for analysis of high throughput sequencing (HTS) reads. The main functionality of NGSEP is the variants detector, which allows to make integrated discovery and genotyping of Single Nucleotide Variants (SNVs), insertions,
Because perceptual grouping organizes the visual scene into units, and because it can operate rapidly across the entire image, we focus here on the possibility that perceptual groups may be crucial higher-units for the rapid extraction of approximate number in random dot arrays. Before our ...
In Experiment 1, decades’ and units’ magnitudes influenced the spatial association of numbers separately. In contrast, in Experiment 2, only the units were spatially associated with magnitude. It was concluded that multiple number lines (one for units and one for decades) can be activated if ...
