Both a and b. Protists can be heterotrophic (organisms that get their nutrition from complex substances) or autotrophic (organisms that make their own nutritional substances).
Speciation, the formation of new and distinct species in the course of evolution.
Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge.
The first one this is because the mutation on the frogs front legs could cause it to be harder to swim and even harder to obtain food.
Cells need to be small in order to make exchanging materials faster. This is because, as the size of the cell increases (if we were to increase the size), then the volume increases faster than the surface area. We want more surface area, so this isn't effective if we increase the size. The larger the size also means that it takes more energy for them to move, so there will need to be more cytoplasm, and that's too much effort to generate. Imagine being in math class when you use those cubes, the one huge cube assembles 100 small cubes, that one huge cube has less surface area than those 100 small cubes combined. That's why we need small cells. A larger surface area allows for more exchanges to occur and a larger volume allows for more materials to be brought in or released from the cell at a given time. (The rate of exchange would increase for larger surface areas and volumes of cells.)
<span>The most important assessment the nurse needs to perform before beginning the pump</span> is Checking for residual stomach contents
It's important to make sure that the stomach is relatively empty before feeding with the pump. Try to withdraw the current stomach content and count it, below 100ml volume should be acceptable.
