Bigeochemical cycles are variety of biological, geological, and chemical processes.
Many elements cycle through ecosystems,
organisms, air, water, and soil. Many of these are trace elements. Other elements, including carbon, nitrogen, oxygen, hydrogen, sulfur, and phosphorus are critical components of all biological life.
Because these elements are key components of life, they must be available for biological processes. The biogeochemical cycles transport and store these important elements so that they can be used by living organisms.

the number of oxygen atoms in each oxygen molecule
Explanation:
The subscript in O₂ signifies the number of oxygen atoms in each oxygen molecule.
An atom is the smallest indestructible particle that takes part in chemical reactions.
Molecules are combinations of atoms. They are usually formed when two atoms combines and shares their valence electrons to form covalent bonds.
- An oxygen molecule O₂ is made up of two oxygen atoms.
- The oxygen atoms are held by covalent bonds.
- The 6 coefficient denotes the volume or number of molecules.

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.
Homologous chromosomes are made up of chromosome pairs of approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci. ... The alleles on the homologous chromosomes may be different, resulting in different phenotypes of the same genes.
Answer:
connective tissue, epithelial tissue, muscle tissue, nervous tissue
Explanation:
epithelial tissues act as coverings controlling the movement of materials across the surface
connective tissues integrates the various parts of the body and provides support and protection to organs
muscle tissues allows the body to move
nervous tissues propagate information
