Answer:
The correct answer is b) When a plant cell is placed in concentrated salt water, water moves out of the cell.
Explanation:
Osmosis is the movement of solvent molecules from an area of less concentration of solute to high concentration of solute to equalize the concentration of both the side of the cell.
So water will move outside the cell when any cell will be placed in a concentrated salt water because the concentration of solute is high in salt water and low inside the cell.
Therefore when a plant cell is placed in salt water the osmosis of water takes place from inside to outside the cell. So the right answer is b.
A small cell lived inside a larger cell to the benefit of both cells.
Hope this helps!
Answer:
The correct answer is - Noctural worms have the advantage over diurnal due to the fact that the nocturnal worms are burrowing during the feeding time of birds.
Explanation:
Natural selection is the process in which organisms adapt according to environmental changes to increase their survival rate. Natural selection leads to natural changes in different organisms.
In this case, diurnal worms are forced by the natural selection here to adapt to the change if they want to survive. Here, natural selection works for the nocturnal and against the diurnal.
Answer:
3) The correct answer would be the third option.
Enzymes are biocatalysts which increases the rate of a biochemical reaction is decreasing the activation energy required by the reaction.
The substrate binds to the active site of the enzyme to form an enzyme-substrate complex. It is then converted to enzyme-product complex. Lastly, the product is released and the enzyme is ready for a new cycle of reaction.
4) The correct answer would be cohesion.
Cohesion or cohesive force refers to the attractive force by which like-molecules are stick together.
For example, water molecules are stick together to form droplets.
