More cells equals more cell divisions.

更胞等于更胞分裂。

And they can do it because they're multicellular, which is a rarity in the microbial world.

它们之所以能够做到这一点，是因为它们是胞，这在微生物世界中很少见。

This is the central problem that all multicellular creatures have to solve.

这是所有胞生物必须解决核心问题。

A younger organism would naturally release more cytokines than and elderly one.

年轻有机体自然会比年老有机体释放更胞因子。

And more cell divisions means more chances of mutations that could let a cell become cancerous.

更胞分裂意味着更可能导致胞癌突。

Eventually those cells-turned-virus-making-factories die, which actually ends up releasing more viruses to infect more cells.

最终那些加工病毒胞工厂死亡，释放出更病毒来感染更胞。

So loose connective tissues have fewer fibers, and more cells and more ground substance.

所以疏松结缔组织有更少纤维，更胞和更基质。

These then leave the host cell and mature, ultimately seeking more T-cells.

病毒接着离开宿主并且发育成熟，最终寻找更T胞。

It’s teacher Rishi Rawat is feeding the computer more samples of cancer cells.

Rishi Rawat老师正在给计算机提供更癌胞样品。

But if you, say, get tossed off a moving motorcycle, you'll lose a lot more layers.

但是如果你从摩托车来，你会脱落更胞层。

Without these elements, plants can't make more cells or even function with the cells they have.

离开了这些元素，植物便无法产生更胞，甚至无法发挥现有胞功能。

They're very old, evolutionarily speaking, and likely resemble some of our first multicellular ancestors.

从进化角度来看，它们非常古老，很可能与我们最早胞祖先相似。

It’s the word for how, as multicellular organisms age, they die more, and reproduce less.

这个词是指随着胞生物衰老，它们死亡得更，繁殖得更少。

Early multicellular life depended on the water in which it lived to support their skeleton-less bodies.

早期胞生命依赖于它生活水来支撑它们无骨架身体。

More cells survived, so the brain decayed less.

更胞存活来，所以大脑腐烂得更少。

The dying cell sacrifices its life so that the group can reproduce--a hallmark of multicellularity.

垂死胞牺牲了自己生命，这样群体就可以繁殖——这是胞生物标志。

As more and more skin cells are made in the matrix, the older cells are pushed out.

随着基质中产生越来越皮肤胞，旧胞被排出来。

IL-5, on the other hand, activates eosinophils which promote an immune response by releasing more cytokines and leukotrienes.

另一方面，IL-5激活嗜酸性粒胞，通过释放更胞因子和白三烯来促进免疫反应。

The tentacled Archaean uses proteins common to multicellular organisms and might lend insight into how the latter evolved.

这种有触角太古代微生物使用胞生物共有蛋白质，这可能有助于我们了解后者进化方式。

First, they're all multi-cellular organisms that don't have any organs.

首先，它们都是没有任何器官胞生物。
