第二个是给他们在时间上有一些变量,就给他们一些flexibility in time,让他们更好去做time schedule,因为新职员向来无法去很好的balance work time and their own time。所以给他们这样一个flexibility,能让他们在工作的同时去找其他工作,...
Biology is a broad field of science that deals with the study of the living world and all of the organisms in it. There are many subfields in biology including ecology, botany, mycology, vertebrate biology, marine biology, cytology, and microbiology to name a few.Answer and Explanation: B...
The mixing-corrected stoichiometric ratio NO:Ofor the North Atlantic Basin of 0.06 nmol/渭mol is in agreement with ratios of NO:Ofor local NO anomalies, suggesting than up to 28% of NO production occurs in the temperate and subpolar Atlantic, an overlooked region for NO cycling. Overall, ...

Narrator: Listen to part of a lecture in a biology class. 旁白:请听一段生物学讲座。 Processor: Ok. 教授:好的。 There are two major types of classifiers in the world, people we call lumpers and people we call splitters. 在世界上有两种分类者,一种被我们称为统合派的人,一种被我们称为分...
Without the ice, species like polar bears cannot successfully hunt seals, which are their only reliable source of food. Sea ice coverage has been decreasing since observations began in the mid-twentieth century, and the rate of decline observed in recent years is far greater than previously ...
The origin and maintenance of social group structure is a topic of central concern in vertebrate biology [1–4]. Whereas one approach is to understand the processes that can account for sociality over an evolutionary scale [5–8], a proximal point of view aims to decipher the mechanisms by ...
There are a number of such regions, ranging from the tropical climate at the equator to the polar climate in the northern and southern extremes. Weather is also influenced by the seasons, which result from the Earth's axis being tilted relative to its orbital plane. Thus, at any given ...
