这种防御系统可以抵御特定的威胁，例如特定的细菌，病毒，朊病毒和霉菌。针对一种病原体起作用的特定防御通常不会对另一种病原体起作用。特定免疫力的一个例子是来自暴露或疫苗的抗性水痘。另一种分组免疫反应的方法是：先天免疫 - 一种遗传或基于遗传易感性的天然免疫。这种免疫力可以防止从出生到死亡。先天免疫包括外部防御（第一道防线）和内部防御（第二道防线）。内部防御包括发烧，补体系统，自然杀伤（NK）细胞，炎症，吞噬细胞和干扰素。先天免疫也被称为遗传免疫或家族免疫。获得性免疫 - 获得性或适应性免疫是身体的第三道防线。这是针对特定类型病原体的保护。获得性免疫可以是天然的或人为的。天然和人工免疫都具有被动和有源部件。主动免疫是由感染或免疫引起的，而被动免疫来自天然或人工获得抗体。让我们仔细看看主动和被动免疫以及它们之间的差异。 澳洲塔斯马尼亚大学 Assignment代写：主动免疫和被动免疫介绍 This line of defenses is active against particular threats, such as particular bacteria, viruses, prions, and mold. A specific defense that acts against one pathogen usually isn't active against a different one. An example of specific immunity is resistance chicken pox either from exposure or a vaccine. Another way to group immune responses is: Innate Immunity - A type of natural immunity that is inherited or based on genetic predisposition. This type of immunity confers protection from birth until death. Innate immunity consists of external defenses (the first line of defense) and internal defenses (second line of defense). Internal defenses include fever, the complement system, natural killer (NK) cells, inflammation, phagocytes, and interferon. Innate immunity is also known as genetic immunity or familial immunity. Acquired Immunity - Acquired or adaptive immunity is the body's third line of defense. This is protection against specific types of pathogens. Acquired immunity may be either natural or artificial in...

一个天生失明的人有梦想，但看不到形象。梦可以包括声音，触觉信息，气味，味道和感觉。另一方面，如果一个人有视力然后失去它，梦想可能包括图像。视力受损（法定盲人）的人在梦中看到了。梦中物体的外观取决于失明的类型和历史。大多数情况下，梦境中的视力与人一生中的视野范围相当。例如，有色盲的人在做梦时不会突然看到新的颜色。随着时间的推移视力退化的人可能会梦想早期的完美清晰或者可能在目前的敏锐度下做梦。戴矫正镜片的有视力的人有很多相同的经历。梦想可能完全是焦点或不是。这些都是基于随着时间的推移收集的经验。盲人但仍然感受到Charles Bonnet综合症的光线和颜色闪烁的人可能会将这些经验融入梦境。奇怪的是，快速的眼球运动，特点是快速眼动睡眠发生在一些盲人，即使他们没有看到梦中的图像。当一个人从出生以来一直失明或者在很小的时候就失明了，那么快速眼球运动不会发生的情况就更可能发生。 澳洲塔斯马尼亚大学 Assignment代写：盲人们看到了什么？ A person who is born blind has dreams, but doesn't see images. Dreams could include sounds, tactile information, odors, flavors, and feelings. On the other hand, if a person has sight and then loses it, dreams may include images. People who have impaired vision (legally blind) do see in their dreams. The appearance of objects in dreams depends on the type and history of blindness. Mostly, the vision in dreams is comparable to the range of vision the person has had throughout life. For example, someone who has color blindness won't suddenly see new colors while dreaming. A person whose vision degraded over time might dream with the perfect clarity of earlier days or might dream at present acuity. Sighted people who wear corrective lenses have much the same experience. A dream may be perfectly in focus or not. It's all based on experience gathered over time. Someone who is blind yet perceives flashes of light and color...
