Explanation:
Each part of your digestive system helps to move food and liquid through your GI track, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool.
The big bang theory states that the universe began approximately 10-20 billion years ago in an expansion of the universe emanating from an extremely compact point. The occurrence of super massive black holes contradict the big bang theory. Super massive black holes are found at the center of galaxies and is what keeps them together. Models do not explain how these would have formed if the big bang occurred the way it was proposed.
Erosion is brought about by the forces of nature or human activity: water, wind, earthquakes, mining, quarrying, etc. In the desert, there is very little water that can cause weathering or erosion, so the most probable answer is wind or maybe even animal activity.
Answer:
Nitrogen fixing bacteria is a type of beneficial bacteria (Cyanobacteria) which has the ability to fix the atmospheric nitrogen into ammonium and nitrates form. This atmospheric nitrogen cannot used by the plants so these bacteria fixes it. This is a symbiotic association between plants and bacteria in which both gets benefit. This nitrogen used by the plants and produces more vegetation cover which is a food source of herbivores such as rabbit.
Answer:
Option "B & C"
B: One structural difference between the two species is the reduced size of the island fox, a feature known as dwarfism.
C: The various island subspecies also differ from each other in size, number of tail vertebrae, and other characteristics.
Explanation:
One notable difference between gray foxes and island foxes is the small size of island foxes. This character (dwarfism) was exhibited by the common ancestor of all six island fox subspecies. Note that the northern Channel Island fox subspecies are more closely related to each other than to any of the southern subspecies, and that the southern subspecies are more closely related to each other than to the northern subspecies.
