Answer:
The given statement is true.
The biogeochemical cycle refers to the cycling of chemical substances or nutrients through the biotic (biosphere) and abiotic (atmosphere, hydrosphere, and lithosphere) regions of the earth.
For example, in the water cycle, water travels or cycle between plants, animals, atmosphere, hydrosphere, and lithosphere.
Other cycles may include a carbon cycle, nitrogen cycle, phosphorus cycle et cetera.
Biogeochemical cycles encompass both living (biotic) and non-living (abiotic) aspects of the environment. These cycles include those of water, carbon, nitrogen, phosphorus, sulfur, and rocks. Hence, it is accurate to state that biogeochemical cycles move through both biotic and abiotic regions.
Biogeochemical cycles do indeed move through both biotic (living) and abiotic (non-living) regions of the earth. This is a fundamental characteristic of these cycles which include the water, carbon, nitrogen, phosphorus, sulfur, and biogeochemical rock cycles. For instance, the water cycle involves water evaporating (abiotic), forming clouds and falling as precipitation, then being taken up by plants (biotic) and returned to the atmosphere through transpiration. Similarly, the carbon cycle includes the process of photosynthesis in plants (biotic), respiration in animals (biotic), rock weathering (abiotic), and the combustion of fossil fuels (abiotic). Therefore, the statement in the question is true.
#SPJ6
You're question is unclear, but I'd go with C.
If a plant has no Casparian strips, it will not be able to control the amount of water it absorbs and solutes. Casparian strips regulate the amount of water that gets to the xylem. Without it, a plant won’t be able to control the amount of water going to the xylem.
Answer:
I, II, and IV only
Explanation:
B) convection
C) insulation
Eliminate
D) radiation
The answer is
Convection currents raise the less dense hot material from the center to the cool crust and material from the cool (dense) crust settles down to the core to be heated again.
b. animal cells contain mitochondria. plant cells do not.
c. animal cells contain chloroplasts. plant cells do not.
d. plant cells are surrounded by a cell wall. animal cells are not.
The statement that correctly describes a difference between plant and animal cell is ; ( D )
Eukaryotic cells which includes plants and animals cells have similar characteristics and slight differences. The main difference between a plant cell and an animal cell is the presence of cell wall in plant cells ( for the purpose of rigidity and protection ) and the absence of cell wall in animal cells and this is because animal cells are not rigid in nature and the cell membrane provides protection and shape for the animal cell.
Hence we can conclude that the the difference between the plant cell and animal cell is, Plant cells are surrounded by a cell wall and animal cells are not.

Answer:
D) Plant cells are surrounded by a cell wall. Animal cells are not.
Explanation:
Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out, thus animal cells do not have cell walls. So therefore, D is the correct answer.
