The skin is an example of a non-specific defense.
For example, bacteria or diseases have trouble entering a healthy person's skin because it is formed by closely packed cells with multiple layers and a substance called keratin that protects is.
On the other hand, the immune system is a specific defense mechanism.
When bacteria is able to enter the body in cases of fever for example, the immune system is activate and sends out protector cells such as the white blood cells to combat infection.
Continuous cell lines can be maintained through an indefinite number of generation :)
"How does carbon enter water?" : Carbon<span> dioxide from the atmosphere dissolves in the surface waters of the ocean. Some of the </span>carbon<span> dioxide stays as dissolved gas, but much of it gets turned into other things. Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the </span>carbon<span> into organic matter.
"How does aquatic plants get carbon" : </span><span>The only difference between photosynthesis in </span>aquatic<span> and land </span>plants<span> is where in their environments they </span>get<span> these nutrients. Land </span>plants get<span> water from the ground through their extensive root system, </span>carbon<span> dioxide from the air through their stomata (tiny holes in a </span>plant's<span> leaves), and energy from the sun.</span>
Answer:
As the beetles have a uniform distribution, at a carrying capacity of 14,600 beetles, there are about 128 beetles per hectare. Because 55 hectares are now unlivable, the carrying capacity would decrease by about 7,040 individuals (55 × 128).
Therefore, the carrying capacity of the ecosystem will be (old carrying capacity – decrease in carrying capacity) = (14,600 – 7,040) = 7,560 beetles.
