Muscles in a kangaroo's legs work because of the cells that make up the muscle which component of cell theory does this best illustrate

As the kangaroo is performing the action of moving, for which it needs a structure and coordination, the cell theory best described in such situation is the one that states that the cell is the basic unit of structure and organization in organisms.

i took the test and i guest the answer terns out letter C is wrong but im pretty sure the answer is B. Cells are the basic unit of structure and function of all living things.

Thanks for reading have a great day!!!

"choosing is refusing" means individuals face an opportunity cost with each decision they make. economists state that every decision involves trade-offs. opportunity cost is the least desirable alternative given up as a result of a decision.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
