I found the full exercise on the internet. Attached is an image of the characteristics and the types of muscle fibres.
Fast twitch:
- few mitochondria (most of the energy comes from acid lactic fermentation)
- low myoglobin content (O2 is not used as the main source of energy)
- shorter twitches
- anaerobic (uses mainly glucose and no O2)
- easily fatigued (as soon as glucose storage finishes fatigue comes in)
- high glycogen content (glucose as the main source of energy and therefore more glucose storage in the form of glycogen)
Slow twitch:
- high myoglobin content (energy comes from O2 and therefore is needed much myoglobin)
- aerobic (uses O2)
- low glycogen content (as O2 is the main source of energy, glucose is not needed as much)
-longer twitches
Answer:
Grasslands and herbivores have a mutually beneficial symbiotic relationship. If larger herbivores such as Kangaroos and Elephants are removed from them, they may become extant.
Explanation:
Herbivores are always hungry and they are always looking for ways to replenish lost energy. Between tree shoots and grass, they often go for the former because they are tender, easier to reach, and less difficult to masticate than the young tree shrubs.
When baby trees become bigger, their shade prevents adequate sunlight from reaching the grass, then gradually they become scanty or subdued for as long as the shade remains.
When large herbivores are removed or leave a grassland, trees have the ability to flourish. Then the results indicated above happens.

The tick uses the dog for two reasons. 1.It uses the dog as a source of food. 2.It also uses a dog for means of transportation from one place too another. And so the dog gains nothing
Answer: The correct answer for the fill in the blank is B) RNA and Proteins.
Ribosome is a molecular machinery, which is located in all living cells. It is formed from proteins and complexes of rRNA ( ribosomal RNA). That is why, it is also called as ribonucleoprotein.
Ribosome serves as the site for protein synthesis. It is primarily divided into two subunits, a larger ribosomal subunit and a smaller ribososmal subunit, which together assist the process of protein formation ( translation).
Thus, the components of ribosomes are RNA and proteins.
