In an Immune disorder, our own defensive cells, get affected. In that situation, they harm us instead of protect us from any other foreign substance (pathogen), that's why it is so dangerous.
Hope this helps!

Answer:
The K-selection reproductive strategy maximizes the survival of offspring by producing <u>few offspring with high levels of parental care.</u>
<u></u>
Explanation:
Depending on how many offsprings members of a species produce and how much care they invest in them, we can divide species into two categories:
- r-organisms. These organisms produce many offspring, sometimes even thousands of them. They live in unpredictable, dangerous environments with a lot of predators. This is why most of their young die. It's important for at least some of them to survive so that they can continue reproducing and keep the species alive. The parents don't invest much care into their young. Some examples of these species are mice, rabbits, weeds, and bacteria.
- K-organisms. These organisms are the opposite of r-organisms. They live in more stable environments, which guarantees that their lifespan will be longer. This is why it's not necessary for them to produce many offspring. Parents invest a lot more care into their young. Some examples of these species are humans, elephants, horses, and primates.
Based on this information, we can conclude that the K-selection reproductive strategy maximizes the survival of offspring by producing few offspring with high levels of parental care.
Cellular Respiration
Explanation:
For something to be living it doesn't need to be a cell or do photosynthesis. Cellular Respiration is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities
