49.【答案】B【解析】A选项意思为“广泛地”;B选项意思为“最新地”;C选项意思为“自然地”;D选项意思为“完美地”.根据后文discovered set of immune cells called T cells(发现了一组新的叫做T细胞的免疫细胞)可知本空意为一组最新发现的免疫细胞叫做T细胞,在当时生物学上还是一片空白。故本题答案为B。
They discovered that the lactase gene variants seen in East Asian people altered the activity of three genes in immune cells, causing them to expand in number. Based on this result, the study authors think it's possible that these variants were selected for because they somehow enhanced the ...
