Proteins.
These four carbon-based molecules are necessary for building an organism.
Relationship:

Nucleic Acids - Proteins -- Blueprint - Building blocks
Amoeba acquires it food by endocytosis, that is, a small region in the plasma membrane which ultimately forms a intra-cellular membrane-bound vescicle. It engulfs it food using its pseudopodia (temporary protrusion of the surface of the amoeboid cell used for feeding and movement) and forms a vacuole around it. When the food is already trapped inside, it releases a digestive enzyme to digest it. Intake of liquid particles is pinocytosis (cell drinking) while intake of solid particles is phagocytosis (cell eating).
The forest would be cooler because the trees are thick and no sunlight is allowed through. things are much cooler when there’s no sunlight allowed near them- think about the difference on a hot summers day sitting in unshaded grass vs sitting in shady grass under a big tree.
The given blank can be filled with a feature resulting from hot volcanic rock.
The geysers refer to the rare characteristics on Earth, only about 1000 of them prevail, and more than half of those are situated in Yellowstone. For a geyser to develop, there must be a source of volcanic heat, enough groundwater, and a geologic plumbing system via which the heated water can escape.
The absconding of water takes place when the groundwater is heated by the hot volcanic rocks. The intensifying steam bubbles push the water above via the fissures in the rock until they overflow from the geyser.
With the absconding of the top layers of the water, the pressure on the hotter waters below diminishes, leading to a violent chain reaction of explosions, which expand the volume of the rising boiling water by up to 1500 times or more.
Answer:
a vestigial structure
Explanation:
Vestigial structures are a rudimentary (or even functionless) version of a body part, but they have important functions in a closely correlated or evolutionarily close species, an example of which is the presence of eyes in fish of the genus Astyanax. The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.
