生物个体

Cellular Senescence is the end of cell proliferation into irreversible G1 growth arrest after certain population doublings, but still maintaining the basic physiological and biochemical activities. It is a kind of cancer-protection mechanism originated from evolution.

细胞衰老是细胞经过一定增殖代数后进入特定G1期生长阻滞，但保持生理生化活性的现象；它是生物进化的结果，也是个体抗癌变的自我保护机制之一。

Increments structure and chemical composition of the statoliths are quite stable and record information about biological, physical and chemical environmental characteristics of different stages of life history.

耳石的轮纹结构与化学组成相当稳定，记录了个体生活过程中丰富的生物-物理-化学环境信息，是一种很好的信息载体。

To provide basic parameters of evaluating the biological safety of xenotransplantation from pig to human, ear tissues from 31 individuals were randomly collected from a Shazi Ling pig population. PCR and RT-PCR were performed to detect porcine endogenous retrovirus proviral DNA and mRNA respectively. The sensitivity of the PCR was evaluated using a positive control.

为评价从猪到人异种移植的生物安全性提供依据，从湖南沙子岭猪的保种群内随机采集31头个体的耳样组织，应用PCR和RT-PCR技术分别检测这些组织中内源性逆转录病毒（porcine endogenous retrovirus，PERV）的前病毒DNA和mRNA，并对PCR扩增的灵敏性进行评估。

All these indicate that the number of individual plants in FS is higher than that in CS; thus, low-intensity surface fire may increase the biodiversity and promote the renewing of Pinus massoniana forest.

火干扰样地中的灌木层马尾松个体数量增加，说明低强度地表火可以增加马尾松林生物多样性和促进马尾松林的更新。

This process is described as 'self-thinning'.

自疏 固着生长的生物，包括植物，不能通过运动逃避竞争，因此竞争中的失败者死去在同样年龄大小的植物群中，这种竞争结果使较少量的较大个体存活下来。

Sessile organisms, including plants, cannot escape competition by movement, and therefore the losers in the competitive battle die. In a group of plants of the same age, this results in fewer individuals of larger size surviving. This process is described as 'self-thinning'.

自疏 固着生长的生物，包括植物，不能通过运动逃避竞争，因此竞争中的失败者死去在同样年龄大小的植物群中，这种竞争结果使较少量的较大个体存活下来。

The biological characteristics are the inherent attributes of human beings, which have strong self-stability and individual independency.

生物特征是人的内在属性，具有很强的自身稳定性和个体差异性，因此是身份验证的理想依据。

Biological characteristic is part of human s intrinsic attribute which has a good self-stability and individual difference, has been enormously valued and developed in the domain of scientific research.

生物特征由于是人的内在属性，具有很强的自身稳定性和个体差异性，在科研领域内得到了极大的重视和发展。

A considerable amount of information is already available, although much of it has been collected by biochemists using a specific food component as a model system

当某些摄入的蛋白质使防御机制产生明显的变化时，便发生人体的生物过敏。这就导致某些个体身上出现各种各样的疾病，且有时是急剧的病情。

More than 90% of Permiangenera of sponges, corals and brachiopods vanished in the extinction.

由于个体种化石的的数量统计随着时间的推移而变化，研究生物灭绝的古生物学家们更倾向于对称为类的有相互联系的整个物种种群进行统计研究。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
