Why doesn't our hands swell up due to osmosis , when we keep it in water for a long time ??
DerKrebs [107]
A cell wall is a permeable layer found in plant cells which acts as a membrane through which water molecules can pass through while animal cells do not have cell walls.. they just have a cell membrane which is selectively permeable to some chemicals or substances.. water does not move from the region of higher to lower concentration in animal cells

In short, plant cells have cell walls that allow osmosis while animal cells do not have cell walls for osmosis to take place

hope it helps you :)

Instead in our hands... something else happens rills or groove shaped lines are formed in our fingers.. it is an adaptation for our body to provide for some friction in water...

If a plant cell contains more solutes than its surrounding environment, what will happen?
larisa [96]
The cell will incorporate solvent - water. When a plant cell contains more solutes than its surrounding environment it means that it is in a hypertonic state, the osmotic gradient will increase and the water will tend to enter the cell augmenting the t<span>urgor pressure inside the cell wall. Ultimately, it will cause water to enter the plant and reach the cell.</span>

Shawn will conduct a study by rolling a toy car down a ramp. He plans to set the
GalinKa [24]

Answer:

  • Independent variable: Car weight (car + block with a mass of 10 grams)
  • Dependent variable: Speed (the time the car takes to descend the ramp)

Explanation:

As you can see in the question above, Shawn wants to check the speed that a car takes when going down a ramp, related to the weight of this case, that is, he wants to know the influence of the weight that the car presents, in its speed in going down a ramp.

In this type of experiment, we can consider the weight that the car presents as the independent variable. This is because independent variables are those that influence a result within the experiment. They happen without the influence of another variable and are factors that impose changes in the analyzed system.

The dependent variable, however, is the car's speed down the ramp. This is because the dependent variables are those that need and are influenced by the independent variable, to achieve a result that can be measured and analyzed.
