For one, increasing the size of each fixation through “training” would be pretty tough, since you would literally have to grow more cones in your eyes.

首先，通过“训练”来增加每次定影范围是相当困难，因为这样你眼睛就要长出更多视锥细胞。

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

With oxygen's role in releasing energy, enabling the release of lots of energy through chemical reaction, it's more useful for animals, and probably led to the evolution of multicellular organisms.

由于氧气在释放能量方面作用，使其能够通过化学反应释放大量能量，所以它对动物更有用，可能还导致了多细胞生物化。

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

最终那些加工细胞工厂死亡，释放出更多来感染更多细胞。

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多癌细胞样品。

And even if we could trick the rest into producing it, then we'd have another problem, more replications means more chances for mutations that could turn a cell cancerous.

即便我们让其余细胞也具备再生能力，同样会产生别问题，更多细胞更新就意味着细胞基因突率也会增大，还可能导致细胞癌。

If blood flow isn't restored soon, more and more cells in the pituitary die, and the pituitary gland progressively shrinks, becomes scarred, and stops producing enough of one or more of hormones.

如果血供不能很快恢复，垂体中就会有更多细胞死亡，而垂体会逐渐萎缩，出现瘢痕，并停止产生足量一种或多种激素。

According to the findings, as hair ages, sheds, and then repeatedly grows back, increasing numbers of McSCs get stuck in the stem cell compartment called the hair follicle bulge, where they remain.

研究结果表明，随着头发老化、脱落，又长出过程，越来越多McSC细胞被困在称为毛囊凸起干细胞室中。

An increase in red blood cells can help a person or group living at high elevations to move and breathe more easily because more red cells can carry more oxygen.

对于生活在海拔较高地方某个人或某群人，增加红细胞可以使他们活动和呼吸顺畅，因为更多红细胞能够携带更多氧气。

A genome map showed that Thiomargarita magnifica has lost some genes needed for cell division and has more than the usual number of copies of genes responsible for cell lengthening.

基因图谱显示，华丽硫珠菌已经失去了一些细胞分裂所需基因，拥有了比通常数量更多负责细胞长基因副本。

The cytokines attract Inflammatory cells like macrophages which start releasing even more inflammatory substances like proteases, platelet activating factor, and free radicals, all which contribute to inflammation.

这些细胞因子可以募集更多炎症细胞如巨噬细胞；这些巨噬细胞而释放更多炎症介质，如蛋白酶、血小板活化因子和自由基，它们都可以一步促炎症反应。

And this isn't just the case for humans — it's true of every animal, plant, and fungus, and nearly every multicellular organism on Earth.

而且这不仅仅是人类情况——每种动物、植物和真菌，以及几乎所有地球上每个多细胞生物体都是如此。

This particular hormone sends a signal to bone marrow for the differentiation of stem cells into more red blood cells to fulfill our body's need.

这种特殊激素向骨髓发出信号，促使干细胞分化为更多红细胞，以满足我们身体需求。

This process, called photosynthesis, led the way for bacteria to multiply into one of Earth's earlier structures: cyanobacteria, formerly called “blue-green algae”.

这个过程-光合作用过程使得这些细菌聚集起来形成地球上最初多细胞结构：藻青菌就是所知“蓝藻”。

It's as if, at one instant in this time we call the Cambrian Era, complex multi-cellular life suddenly emerged almost intact on the planet.

在寒武纪一段很短时间里，各种复杂多细胞生物突然横空出世。

Even further down at 3,600 meters is the deepest point that a multicellular organism has been found alive — this freaky looking worm.

再往下3600米深处，是目前发现有多细胞生物生存最深处——这种看起来怪怪蠕虫。

But last summer, an underwater vehicle peeked beneath shelves of volcanic rock in the Pacific and found a bustling community of multicellular organisms.

但今年夏天，一辆水下探测器在太平洋火山岩层下窥探，发现了一个热闹多细胞生物群落。

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多细胞生物共有蛋白质，这可能有助于我们了解后者化方式。
