Tissues is just below organs in complexity.
A tissue is a collection of cells and extracellular matrix from the same origin that work together to perform a defined function. Multiple tissues are then functionally grouped together to form organs.
The hierarchy is the following (from the most simple to most complex):
1. Cell
2. Tissue
3. Organ
4. Organ system
5. Organism

Answer: Stem cell research has the potential to treat diseases that are currently burdened with high health care costs—especially chronic conditions such as heart disease, Alzheimer's disease or diabetes, the costs of which threaten to cripple the healthcare system.
Answer: The work done by the ramp against the force of gravity is -343 J
Explanation:
Work is defined as the force that is causing the movement or displacement of an object.
Mathematically,
We know that:
where,
W = work done by the ramp = ?
m = mass of the box = 7 kg
g = acceleration due to gravity = (Negative sign appears because it is acting against the gravity)
d = displacement = 5 m
Putting values in above equation, we get:
Hence, the work done by the ramp against the force of gravity is -343 J
