Biogeochemical cycle are cycles of materials through the biotic and abiotic components of earth.
A biogeochemical cycle refers to the processes through which an element or compound like water moves between its different living and nonliving forms and places in the biosphere.
- The biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfur are crucial to living things.
- Heat is produced as energy moves through an ecosystem, yet chemical components are recycled.
- Elements are carried through biogeochemical cycles in a number of ways, from the nonliving (abiotic) to the living (biotic) components of the biosphere, and back again.

Your answer would be C as a physical change is characterized as a change in physical appearance be it shape, phase, or size. A good example is an ice cube when it melts, it may look different but its chemical composition is the same and the change from is ice to water is reversible unlike a chemical change like baking a cake which cannot be reversed to its original state before it went into the oven. Hope this helps!
The anterior ventral rootlets carry MOTOR NEURONS impulses to the spinal nerves.
The anterior ventral rootlet is the one responsible for carrying motor neurons impulses from the spinal cord to the periphery. The cell bodies of the motor neurons are located in the gray matter of the spinal cord.
Answer:
Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).
Explanation:
Answer:
Explanation:
a)Organ transplantation requires that the donor organism and recipient be genetically close so that the graft or transplant will not be attacked by the immune system of the recipient leading to rejection and damage. Squeaky is likely to be made up of a different genetic configuration compared to laboratory inbred FG426 mouse
b) ips (induced pluripotent stem cell) on the other hand can benefit squeaky since the cells are somatic cells such as B cells, Keratinocytes, neuronal progenitors cells, kidney and muscles gotten from the donor that are reprogrammed by reactivating silent genes through fusing of another different cell such as ES (embryonic stem cell) and introduction of some transcriptional factors such oct4, sox2,kf4, and k-myc leading to transcriptional activity and DNA methylation. This induced pluripotent stem cells can be grown into organ that can be transplanted to the recipient who was initially the donor of the reprogrammed somatic cells. Because it is from the host, the transplanted organ is not likely to trigger immune response compare to those grown from ES from other bred.
