The Lithosphere contains all of the cold, hard, solid rock of the planet's crust, the hot semi-solid rock below the crust, the hot liquid rock near the center of the planet, and the solid iron core. The biosphere is the sphere that contains all of the Earth's living organisms. The organisms and crust interact through events between spheres, such as natural events like floods, shifts in the Earth's crust. Some event as such could create soil erosion resulting in decreased vegetation and increase death of organisms. <span>

Unsaturated fatty acids are a component of the phospholipids in cell membranes and help maintain membrane fluidity. The Phospholipids contain a variety of unsaturated fatty acids, when compressed, the “kinks” in their tails push adjacent phospholipid molecules away, that helps in maintain fluidity in the membrane. Unsaturated fatty acids have at least one double bond, creating a "kink" in the chain, the absence of double bonds decreases fluidity, making the membrane very strong and stacked tightly.
The ratio of saturated and unsaturated fatty acids determines the fluidity in the membrane at a temperature, at appropriate temperatures the phospholipids have enough kinetic energy to overcome the intermolecular forces holding the membrane together, which increases membrane fluidity.

I'm assuming a carnivore as they are animals that only eat meat
Answer:
Answer B.
Explanation:
Biological Fitness, also called darwinian fitness, means the ability to survive to reproductive age, find a mate, and produce offspring. basically, the more offspring an organism produces during its lifetime, the greater its biological fitness.
They are multicellular, heterotrophic, they have no respiratory organs, and their digestion is intracellular!
