Answer:
If the percent concentration is greater in the fluid outside a cell than inside a cell, water will flow out of the cell. If the percent concentration is equal both inside and outside a cell, water does not move into or out of the cell.

Answer:
- If it were true, all organisms would be complex and simple organisms would disappear
- It does not account for genetic mutations known to affect physical traits
Explanation:
Lamark's theory of evolution is that changes in the organism's physical form during its lifetime can be passed on to its offspring. In other words, he believed that children can inherit acquired characteristics from their parents.
The classic example is that he believed giraffes evolved long necks because they would stretch upwords to eat leaves from tall trees, elongating their necks, and then would pass on a longer neck to its children. Or in humans, that a body builder would make a muscular child because of their intense training!
There are a few problems with this theory:
- If we believe this theory, organisms would always be getting more and more complex and 'improved', so simple organisms would disappear.
- We know that changes to the DNA influence inherited physical characteristics, not simply continued use

Answer:
It depends on the type of microscope that you have
Explanation:
For example, in the case that you have a fluorescence microscope, it is possible to create a fusion construct of the domain fused to the Green Fluorescence Protein (GFP) and then introduce it into the cell. The observation of fluorescence from this construct enables to confirm the existence of the signal sequence (i.e., the C-terminal domain) in the organelle
