The way that does not successfully classify protists is their size. Thus, the correct option is C. 
<h3>What are Protists?</h3>
Protists may be defined as one of the diverse taxonomic groups and particularly a kingdom of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that generally include the protozoans, most algae, and often some fungi. 
On the basis of the way that Protists reproduce, they can be subdivided into three types: Sexually reproducing protists, asexually reproducing protists, and conjugation-based. 
On the basis of how protists get energy and food, they are again subdivided into three categories. 
- Animal-like protists: Heterotrophs that have the ability to move.
 - Plant-like protists: Autotrophs that have the ability of photosynthesis. 
 - Fungi-like protists: Heterotrophs have cells with cell walls. 
 
On the basis of the way that they move, they are subdivided into two types: Motile protists and non-motile protists. They generally move with the help of cilia, flagella, and pseudopodia. 
Therefore, the size is not one of the following ways that protists are grouped. Thus, the correct option for this question is C.

A convincing explanation of why some lineages survived while others vanished is still lacking in the hypothesis of an asteroid impact as the cause of the end-cretaceous mass extinction.
<h3>What is an 
asteroid?</h3>
One of the smaller planets in the inner Solar System is an asteroid. Asteroids are metallic or rocky bodies without an atmosphere, ranging in size from 1-meter pebbles to a dwarf planet with a diameter of over 1000 km.
The majority of the one million or more known asteroids are concentrated in the main asteroid belt, which is 2 to 4 AU from the Sun and between the orbits of Mars and Jupiter. The three categories of asteroids that are typically recognized are C-type, M-type, and S-type. 
These were given their names and are frequently associated with, respectively, carbonaceous, metallic, and silicaceous compositions. The largest asteroid, Ceres, has a diameter of over 1,000 km (600 mi), making it a dwarf planet.

The answer is respiration.
The burning of fossil fuels is known as combustion. It is often compared with cellular respiration. 
The general equation of cellular respiration is:
glucose + oxygen → <span>water + carbon dioxide
</span>
The general equation of combustion is:
fuel + oxygen → <span>water + carbon dioxide
Both reactions involve breaking down of large molecules (glucose and fuel) using oxygen into water and carbon dioxide. In both reactions, chemical energy is transformed into more useful form.</span>
